feat(discovery): version-aware cache filtering + --exclude-cache flag (v5.9 B3a) [skip-docs]

Browse source 
Stale ~/.claude/plugins/cache versions polluted token-hotspots ranking and
inflated CNF duplicate-hook findings with config that loads on zero turns.
installPaths point INTO the cache, so a blunt "skip all of plugins/cache"
would drop ACTIVE plugins — the filter is therefore version-aware: it reads
the adjacent installed_plugins.json, keeps active version dirs, drops only
stale ones (and exposes them via discovery.staleCacheVersions for B3b).

- file-discovery: cacheVersionKey() + applyCacheFilter() (active vs stale via
  installed_plugins.json; HOME-independent, derives the manifest from the cache
  path); discoverConfigFiles/Multi gain { excludeCache } + staleCacheVersions.
  Absent/unparseable manifest -> no filtering (never silently drop live config).
- token-hotspots-cli + scan-orchestrator: --exclude-cache (default ON for these
  live-cost scans) / --no-exclude-cache restores the full walk.
- Tests: cacheVersionKey unit cases; stale-dropped/active-kept/no-manifest
  discovery cases; CNF-drop proof (soft-spot verified, not assumed:
  include=1 -> exclude=0 duplicate-hook findings).
