feat: paired review system overhaul — unified service, configurable agents, silent output removal

- Remove UNIFIED_MODE legacy: single service manages all 3 Discord bots
- Add OWNER_AGENT_TYPE / REVIEWER_AGENT_TYPE env vars for configurable agent selection
- Fix Discord channel routing: reviewer output goes through correct bot (discord/discord-review)
- Fix channel name assignment: explicit names prevent agentTypeFilter collision
- Remove silent output suppression system: harness-level protections replace prompt workarounds
- Add reviewer approval detection: DONE marker on first line stops ping-pong
- Include user's original message in reviewer prompt for context
- Fix round_trip_count auto-reset on new user message
- Fix session ID conflict: reviewer doesn't reuse owner's session
- Fix pending progress text flush in runner on close sentinel
- Promote buffered intermediate text to final result when result event has no text
- Remove legacy files: .env.codex.example, .env.codex-review.example, migrate-unify.cjs
- Update CLAUDE.md: server-side build deployment, unified architecture docs

 ## Quick Context
 
-Two systemd services (`ejclaw`, `ejclaw-codex`) share the same codebase but run with separate stores, data, and groups (will be unified — DB supports shared access via WAL mode + service partitioning). Agents run as direct host processes (no containers). Claude Code uses the Agent SDK; Codex uses the Codex SDK (`codex exec`). Auth via `CLAUDE_CODE_OAUTH_TOKEN` in `.env` (1-year token from `claude setup-token`).
+Single unified service (`ejclaw`) manages three Discord bots (Claude, Codex-main, Codex-review) in one process. Owner/reviewer agent types are configurable via `OWNER_AGENT_TYPE` and `REVIEWER_AGENT_TYPE` in `.env`. Claude Code uses the Agent SDK; Codex uses the Codex SDK (`codex exec`). Auth via `CLAUDE_CODE_OAUTH_TOKEN` in `.env` (1-year token from `claude setup-token`).

-- `ejclaw.service` — Claude Code bot (`@claude`), `SERVICE_ID=claude`, `SERVICE_AGENT_TYPE=claude-code`
+Single unified service manages all three Discord bots in one process:
-- `ejclaw-codex.service` — Codex bot (`@codex`), `SERVICE_ID=codex-main`, `SERVICE_AGENT_TYPE=codex`
+- `ejclaw.service` — Unified process, `UNIFIED_MODE=true` (default)
-- `ejclaw-review.service` — Codex reviewer bot (`@codex-review`), `SERVICE_ID=codex-review`, `SERVICE_AGENT_TYPE=codex`
+- Discord bots: `DISCORD_BOT_TOKEN` (Claude), `DISCORD_CODEX_BOT_TOKEN` (Codex-main), `DISCORD_REVIEW_BOT_TOKEN` (Codex-review)
-- All services share the same codebase (`dist/index.js`), differentiated by env vars
+- Paired review: owner (`OWNER_AGENT_TYPE`, default: codex) ↔ reviewer (`REVIEWER_AGENT_TYPE`, default: claude-code)
-- Unified dirs (`store/`, `groups/`, `data/` shared by all services):
+- Reviewer fallback: Claude 429/한도초과 시 codex-review로 자동 핸드오프
-  - `router_state`: keys prefixed with `{SERVICE_ID}:` (e.g., `claude:last_timestamp`)
+- Shared dirs: `store/`, `groups/`, `data/`
-  - `sessions`: composite PK `(group_folder, agent_type)`
-  - `registered_groups`: filtered by `agent_type` on load
 - SQLite WAL mode + `busy_timeout=5000` for concurrent access
