Resolve pack_format from the pack's mcVersion

The previous hardcoded pack_format 34 + supported_formats 34..75
covered 1.21 through 1.21.11 only, so a pack generated for the
current latest (26.1.2 → format 84) was rejected as outdated.

Add src/installer-rp/packFormat.ts with a 1.21 → 26.2 lookup table
from the Minecraft wiki and resolveResourcePackFormat() that returns
{matched, format}. Unknown mcVersion falls back to the table's most
recent entry, with a log line warning the user.

Plumb mcVersion through the load → install flow:
- rp:packs:load now also fetches /manifest/<key>.json alongside
  /file/list/<key>.json and runs it through the existing
  normalizePackDefinition so the editor and the installer agree on
  the mcVersion shape. Pack manifest load failures fall back to an
  empty mcVersion (which then triggers the latest-format fallback).
- RpFetchedPack carries mcVersion; the install handler hands it to
  buildResourcepackZip.
- buildResourcepackZip drops the constant pack_format / supported_
  formats and uses the resolved format both as pack_format and as
  the {min,max} of supported_formats. Each pack is thus pinned to
  exactly the MC version it was authored for.
- The renderer's pack card now shows "마인크래프트 <version>" in
  the small line so the user can confirm before installing.

Verified locally: pack.mcmeta generated for mcVersion "1.21",
"1.21.6", "26.1.2", and the bogus "99.9.9" produce pack_format
34 / 63 / 84 / 86 (last falls back to the table tail) respectively.
