feat(editor): add --catalog-pluck cross-format entry lookup

New utility extracts a single entry by id from any
registered catalog format without dumping the whole file.
Useful when a catalog has hundreds of entries and you
only want to inspect one — e.g. "show me WBOS encounter
102" or "what's in WHRT bind 204".

Auto-detects format from the file's 4-byte magic, looks
up the registered --info-* flag in the format table,
spawns that handler as a subprocess with --json, then
filters the entries[] array to just the matching id. The
primary-key field is auto-discovered: prefers the first
*Id field that ISN'T a known foreign-key reference (mapId,
areaId, spellId, npcId, factionId, etc. — 25 known
external-ref names filtered out). Falls back to first
remaining *Id, then first numeric field.

Without the foreign-key filter, alphabetical key
iteration in nlohmann::json picks the wrong field — for
WHRT entries with both areaId and bindId, naive code
would identify by areaId and miss obvious lookups.
Caught during smoke-test and fixed before commit.

Output formats: terminal table (default) or --json.
Accepts file path with or without the .wXXX extension.
CLI flag count 1111 -> 1112.
