feat(tokens): stale plugin-cache disk-cleanup finding, honestly labelled Dead config (v5.9 B3b)

Browse source 
The B3a cache filter already exposes discovery.staleCacheVersions; surface them
as a finding so the user knows the superseded plugin versions are safe to delete.

Honesty (Verifiseringsplikt): the finding loads on ZERO turns, so it must NOT
read as a per-turn token cost. TOK normally humanizes to "Wasted tokens"; a new
per-finding category override ('plugin-cache-hygiene' -> "Dead config") plus a
dedicated humanizer translation ("Old plugin versions are sitting on disk (safe
to delete) ... cost zero tokens per turn ... housekeeping, not a performance
problem") keep the prose accurate instead of the generic "using more space"
default. evidence carries the explicit "zero live-context impact" note.

- token-hotspots: Pattern H emits CA-TOK (low) from discovery.staleCacheVersions
  when stale versions exist (`--global`); silent otherwise.
- humanizer: CATEGORY_TO_IMPACT lets a finding's category override the
  scanner-default impact label (raw `category` field unchanged -> --json/--raw
  byte-stable). humanizer-data: honest static translation for the finding.
- Tests: finding fires/severity/category, lists stale keys + zero-impact note,
  silent when none; humanizer override -> Dead config; honest translation locked.
- Docs: tokens command render note (disk-cleanup, not a token problem) +
  --no-exclude-cache flag; README + CLAUDE.md rows (7 patterns, cache-aware).

|---------|-------------|
| `/config-audit` | Full audit with auto-scope detection (no setup needed) |
| `/config-audit posture` | Quick health scorecard (A-F grades, 10 quality areas incl. Token Efficiency, Plugin Hygiene) |
| `/config-audit tokens` | prompt-cache-aware token hotspots (6 patterns: cache-breaking, redundant perms, deep imports, oversized cascade, bloated SKILL.md desc, MCP tool-schema budget), each ranked hotspot tagged with its load pattern (always / on-demand / external) — optional `--accurate-tokens` API calibration, `--with-telemetry-recipe` cache-hit recipe pointer |
| `/config-audit tokens` | prompt-cache-aware token hotspots (7 patterns: cache-breaking, redundant perms, deep imports, oversized cascade, bloated SKILL.md desc, MCP tool-schema budget, stale plugin-cache disk-cleanup), each ranked hotspot tagged with its load pattern (always / on-demand / external) — **cache-aware** (stale `~/.claude/plugins/cache` versions excluded by default; only each plugin's active version counts; `--no-exclude-cache` for the full walk), optional `--accurate-tokens` API calibration, `--with-telemetry-recipe` cache-hit recipe pointer |
| `/config-audit manifest` | Ranked table of every token source (CLAUDE.md, rules, agents, skills, output styles, MCP, hooks) sorted by estimated tokens, each tagged with its load pattern (always-loaded / on-demand / external) + an always-loaded subtotal ("tokens that enter context every turn") |
| `/config-audit feature-gap` | Context-aware feature recommendations grouped by impact (incl. a conditional `disableBundledSkills` lever when the active skill listing is over budget — remediation companion to SKL `CA-SKL-002`) |
| `/config-audit optimize` | Optimization lens (mechanism-fit) — config that works but fits a better mechanism: procedure→skill (CA-OPT-001, deterministic), lifecycle→hook / unscoped path→rule / "never"→permission (prose-judgment via opus `optimization-lens-agent`). Hybrid motor; every finding cites a best-practices-register rule. Agent-driven, **not byte-stable** |
