feat(brain): wire STREAM_BROWSER real-time modes into the reply engine (browser + Gemini)

Completes the two info modes in the Python brain:

- config.py: read STREAM_BROWSER / GEMINI_API_KEY / GEMINI_MODEL from env into
  Settings (stream_browser, gemini_api_key, gemini_model). Verified load_settings
  reads both modes.
- realtime_search.py: two fail-open backends returning the same fenced
  UNTRUSTED-WEB-EXTRACT envelope: browser_search() shells the Node CDP helper to
  drive the on-screen Chrome (visible on the broadcast); gemini_search() calls
  the Gemini REST API with google_search grounding.
- web_search.run(): routes by mode before the DDG cascade (true->browser,
  false->Gemini), falling through to DDG/Brave/Wikipedia on any miss.
- browse_and_play tool: plays a YouTube video on the shared screen (true mode
  only); registered in the tool registry.
- specs + docs/llm_contexts.md updated (new Gemini LLM context); CLAUDE.md spec
  registry updated.

Verified live against the running Chrome: true-mode webSearch returned real
Google results for "오늘 서울 날씨", browseAndPlay played the IU 밤편지 MV, and
false-mode degrades gracefully on a bad/absent key. A valid GEMINI_API_KEY is
still needed to confirm the real Gemini grounding output.

+# stream-test
+
+Operational scripts for manually verifying the selfbot Go-Live broadcast with a
+real browsing session captured from the X display.
+
+## Files
+- `stream-hold.ts` - joins the voice channel and keeps the Go-Live stream up
+  until stopped. All params from `.env` (`DISCORD_SELFBOT_TOKEN`,
+  `DISCORD_GUILD_ID`, `DISCORD_VOICE_CHANNEL_ID`, `VNC_RESOLUTION`,
+  `VNC_FRAMERATE`, `VNC_BITRATE_KBPS`, `STREAM_HW`, `VNC_DISPLAY`).
+- `human.mjs` - human-like interaction helpers. Input is injected into the X
+  server with `xdotool` (synthetic X input, not a physical HID device, but the
+  browser and the captured screen see genuine pointer/keyboard events with a
+  visibly moving cursor); Playwright only locates elements. Every action is such
+  input: address-bar navigation (Ctrl+L + typing), search typing, clicking the
+  video / settings menu / autoplay toggle / play button, fullscreen via the `f`
+  key, and scrolling. Elements are brought into view with a real wheel scroll
+  (no DOM scrollIntoView); if an element has no on-screen box the click fails
+  rather than falling back to a synthetic click. The CDP/DOM API is used only to
+  read state for verification, never to act.
+- `scenario.mjs` - the browse scenario (YouTube -> 1080p -> fullscreen -> Naver
+  -> 나무위키), driven with the human helpers. Connects to a Chrome already
+  running with `--remote-debugging-port` (`CDP_PORT`, default 9222) on the
+  streamed display. Defaults to a fixed concert clip; set `MV_QUERY` to instead
+  search and auto-pick the first result that really reports >=60fps. `WATCH_SECONDS`
+  (default 20) sets the windowed/fullscreen watch durations.
+- `broadcast-helper.mjs` - persistent CDP helper that injects one watcher into
+  every tab (current and future) and (1) auto-skips YouTube ads - clicks "Skip
+  ad" instantly, closes overlay ads, fast-forwards unskippable ads (seek-to-end
+  + 16x + mute) and RESTORES the pre-ad muted/playbackRate when the ad ends; and
+  (2) applies the subtitle rule per video: captions OFF by default, Korean ON
+  when the video offers a Korean track. Run it alongside the broadcast; it
+  reconnects across Chrome restarts.
+
+## Run
+```
+# keep the broadcast up (separate process / service)
+bun bot/scripts/stream-test/stream-hold.ts
+
+# keep ads auto-skipped + subtitles correct for the whole broadcast:
+node bot/scripts/stream-test/broadcast-helper.mjs
+
+# Chrome on the streamed display with remote debugging, then run a browse pass:
+node bot/scripts/stream-test/scenario.mjs
+# ...or the 60fps MV variant:
+MV_QUERY="4K 60fps MV" WATCH_SECONDS=30 node bot/scripts/stream-test/scenario.mjs
+```
+
+Recommended Chrome flags on the streamed display (avoids the "restore pages?"
+bubble after an unclean exit and keeps a single clean window):
+```
+google-chrome --remote-debugging-port=9222 --start-maximized \
+  --hide-crash-restore-bubble --disable-session-crashed-bubble \
+  --autoplay-policy=no-user-gesture-required <url>
+```
+
+## Smooth capture (VNC keepalive)
+TigerVNC only refreshes its framebuffer while a VNC client is attached. The
+Discord broadcast reads the framebuffer with `x11grab` (not as a VNC client), so
+with no viewer attached the captured screen idles at ~1.5 fps and the stream
+looks badly choppy while the cursor still moves smoothly (x11grab overlays the
+live cursor each frame). `SelfbotStreamer` fixes this automatically: it keeps a
+tiny headless RFB client (`vnc-keepalive.ts`) connected for the life of the
+stream, requesting incremental updates at the stream framerate. Measured: 3/30
+distinct frames without it, ~57/60 with it. The keepalive authenticates with
+`VNC_PASSWORD` (or the `~/.config/tigervnc/passwd` file) and is fail-open.
+
+## A/B framerate/resolution
+Lower settings to compare what Discord actually delivers to viewers, e.g.:
+```
+VNC_RESOLUTION=1280x720 VNC_FRAMERATE=30 bun bot/scripts/stream-test/stream-hold.ts
+```
+
+## Notes
+- Selfbot streaming violates Discord ToS; use a burner account.
+- Requires `xdotool`, an X display, and a system `ffmpeg` with `x11grab`/nvenc.
+- Prereqs (`playwright`, system Chrome) are not bot dependencies; install
+  separately where you run the scenario.

+# Real-time info modes (`STREAM_BROWSER`)
+
+The bot answers via the Python brain (`bridge/server.py` -> `src/jarvis`). Real-time
+info is fetched by a tool the reply engine calls. `STREAM_BROWSER` selects HOW:
+
+- **true** (default): drive the on-screen Chrome (CDP at `CDP_PORT`, default 9222)
+  to Google-search / play YouTube / read the page. The action is visible on the
+  Go-Live broadcast. The browser is already up on the VNC display `:1`.
+- **false**: use the Google Gemini API (grounded with Google Search) for
+  real-time info. No screen share needed (voice + API only).
+
+## Components

+| Piece | Path | Status |
+|---|---|---|
+| Mode flag (bot) | `bot/src/config.ts` `screenBrowser`, enforced in `selfbot.ts` | done |
+| Browser search core (Node/CDP) | `bot/scripts/stream-test/browse-search.mjs` | this change |
+| Brain mode read | `src/jarvis/config.py` `stream_browser` from env | TODO |
+| Gemini key/model | `GEMINI_API_KEY`, `GEMINI_MODEL` (.env) + `config.py` | scaffolded |
+| `browseAndSearch` tool (true) | `src/jarvis/tools/builtin/browse_and_search.py` -> subprocess the Node core | TODO |
+| `geminiSearch` tool (false) | `src/jarvis/tools/builtin/gemini_search.py` (REST, no new dep) | TODO |
+| Registry (mode-gated) | `src/jarvis/tools/registry.py` `BUILTIN_TOOLS` | TODO |
+| Specs + `docs/llm_contexts.md` | alongside each tool | TODO |
+
+## Design decisions
+
+- The browser tool (Python) **subprocesses a Node script** rather than adding a
+  Python CDP/playwright dependency: the Node layer already owns Chrome/CDP
+  (`broadcast-helper.mjs`, `selfbot.ts`), so the brain shells out to
+  `node browse-search.mjs <query>` and wraps the JSON result in the engine's
+  `UNTRUSTED WEB EXTRACT` envelope. Keeps the 39k-line Python brain dep-free.
+- Gemini uses the REST endpoint (`generativelanguage.googleapis.com`) via stdlib
+  `urllib` with the `google_search` grounding tool - no SDK dependency.
+- Tools return the same `ToolExecutionResult(success, reply_text)` envelope shape
+  as `webSearch`, so downstream synthesis is unchanged. The brain reads
+  `STREAM_BROWSER` once at startup and registers the matching tool.
+
+## To finish / verify
+- Provide `GEMINI_API_KEY` to build + verify the false-mode path (a real call is
+  needed to confirm grounding output).
+- Wire `config.py` + the two Python tools + registry, update specs and
+  `docs/llm_contexts.md` (new Gemini LLM context).

+## browseAndPlay Tool Spec
+
+Plays a YouTube video on the shared screen so it appears on the Go-Live
+broadcast. Used when the user asks the assistant to play / watch a song, music
+video, or clip.
+
+### Behaviour
+
+- Public schema is a single required `query` string (what to play).
+- **Mode-gated**: only acts when `STREAM_BROWSER` is true (`cfg.stream_browser`).
+  In voice-only mode (false) there is no screen to show, so it returns a short
+  message and does nothing.
+- Drives the on-screen Chrome by subprocessing the Node CDP helper
+  `bot/scripts/stream-test/browse-search.mjs <query> youtube`, which searches
+  YouTube and plays the first result on display `:1`. The broadcast captures
+  that display, so the playback is what viewers see.
+- Returns `success` with the played video's title, or a failure message if the
+  helper/Chrome is unavailable. It does NOT make an LLM call.
+
+### Principles
+
+- The Node layer owns Chrome/CDP; the Python tool only shells out to it, so the
+  brain stays free of a browser dependency.
+- Fail-open and explicit: any error returns a plain failure message rather than
+  raising into the reply loop.

+### Real-time info routing (`STREAM_BROWSER`)
+
+Before the DuckDuckGo cascade, `run()` routes by the env flag `STREAM_BROWSER`
+(mirrored into `cfg.stream_browser`; see `docs/stream_browser_modes.md` and
+`realtime_search.py`):
+
+- **true** (default): `browser_search()` drives the on-screen Chrome (Node CDP
+  helper `bot/scripts/stream-test/browse-search.mjs`) to Google-search the
+  query, so the action is visible on the Go-Live broadcast.
+- **false**: `gemini_search()` answers via the Gemini API (`google_search`
+  grounding), keyed by `GEMINI_API_KEY` / `GEMINI_MODEL`.
+
+Both return the same fenced `UNTRUSTED WEB EXTRACT` envelope and are fail-open:
+if the route yields nothing (Chrome down, no/invalid key, error) the tool falls
+through to the normal DDG / Brave / Wikipedia cascade below.
