fix(classifier,gate): G parser-quirks + H unknown-not-blocking + A1/A2/B3/C1

Brain-retro #6 follow-up #2 (consolidated). Eight independent fixes:

A1 — task_cost wiring (cost tracking)
  - router-prehook.mjs: capture classifier LLM usage via onUsage callback,
    persist to state.task_cost.classifier_input_tokens / output_tokens.
  - observer-transcript-parser.mjs: merge router-state.task_cost on top of
    extractTokenUsage(turn). State-file values win for classifier/
    self_assessment/reviewer fields.
  - New buildCostFromClassifierUsage() exported from router-prehook.
  - Verified live: state file now shows real input_tokens=190 /
    output_tokens=598 / cache_read=10075 (was 0 before).

A2 — self-assessment coverage
  - observer-self-assessment-api.mjs: DEFAULT_TIMEOUT_MS 10s -> 30s.
  - .claude/settings.json: Stop-hook timeout 15s -> 60s.
  - Same Windows TLS handshake issue. Was 85% no_self_assessment in retro #6.

B3 — brain-retro SKILL.md reconciliation
  - Step 5b: batch=default for N>=20, subagent for N<20.

C1 — dead-code cleanup
  - Removed recommendNode import + getClassificationMap + getDormancy from
    observer-transcript-parser.mjs.

G — parseClassifierResponse Pass 3 (fixLLMJsonQuirks)
  - Root cause: real Sonnet output sometimes contains raw newlines inside
    string values (multi-line reason_for_choice) and trailing commas, which
    strict JSON.parse rejects. Result was llm_error_type=parse_null on
    every other call, falling back to regex with task_type=unknown.
  - Fix: after Pass 1 (clean) and Pass 2 (brace-extract) fail, try Pass 3
    that escapes raw newline/tab inside string values and strips trailing
    commas before final JSON.parse attempt. Pure char-walk, no JSON5 dep.

H — 'unknown' added to NON_BLOCKING_TASK_TYPES in router-tool-gate.mjs
  - Until G fully proves itself, blocking Bash/Edit on unknown is too strict.
    With G in place, parse_null should be rare; H gives a safety net.

Tests added: +9 across 5 test files. Regression: 913 vitest tests in tools/.

4. **Update read-counter**: run `node tools/observer-of-observer.mjs record`. This atomically bumps `docs/observer/.read-counter.json` `last_read_at` to now and increments `read_count_last_period`. (Side-effect — used by C3 observer-of-observer for 54-week self-prune detection.)
5. **Run the deterministic analyzer**: `node tools/brain-retro-analyzer.mjs docs/observer/episodes-YYYY-MM.jsonl` (pass every monthly file in the period). It returns JSON with `episodeCount`, `observerErrorCount`, `tasks` (episodes grouped into tasks), `causalChains` (error→fix candidates) and `factorMatrix` (outcome distribution per factor). The analyzer deduplicates the routing-gate double-write and infers the true `outcome` of each episode from the next episode's `prompt_signal` — never trust the stored `outcome` (it is `unknown` at write time).
5a. **[Phase 3] Sanity questions (spec §4.7)** — `node tools/brain-retro-sanity-generator.mjs` (called as a module from analyzer-driven flow, OR direct via `import { generateCandidateQuestions } from '../../../tools/brain-retro-sanity-generator.mjs'`) returns up to 5 candidate questions. Pick 3-4, ask via AskUserQuestion (multiple-choice + free comment). **Вопросы заказчику — простым языком**, не «rework / wrong_skill / TDD pattern / self_assessment», а «переделки / выбор не того инструмента / самопроверка» (memory `feedback_plain_language.md`). Если первый раунд содержит жаргон — переформулировать и переспросить. **Before persist:** sanitize free comments with `tools/observer-pii-filter.mjs` (`sanitize` export, RU_PHONE / EMAIL / TOKEN strip). Write answers to `docs/observer/sanity-checks/YYYY-MM-DD.json` `{schema_version: 1, questions: [...]}`.
5b. **[Phase 3] Reviewer subagent pickup (spec §4.6)** — for each unreviewed episode in the period: `Task(subagent_type='reviewer-agent', prompt=<episode JSON + sanity-answers context>)`. Parse the returned JSON, write `review.*` + `outcome_reviewed` + `outcome_reviewed_source` into the episode. Per-episode try/catch — on subagent crash/timeout, fall back to `tools/brain-retro-opus-reviewer.mjs` `reviewViaDirectApi(episode)` (direct Opus API). If both fail, leave `review.reviewer_error: <msg>` for the next retro.
5b. **Reviewer pass**pragmatic two-mode policy (added 2026-05-26 after brain-retro #6, replacing original spec §4.6 «subagent only» which was unrealistic at retro scale):
- **Batch mode (default, fast)** — `node tools/brain-retro-batch-reviewer.mjs docs/observer/episodes-YYYY-MM.jsonl <cutoff-iso> [limit=30] [conc=5]`. Direct Opus API via `reviewViaDirectApi` from `tools/brain-retro-opus-reviewer.mjs` with concurrency 5. Use for **N ≥ 20 unreviewed episodes** — typical retro workload (retro #6 processed 132 episodes in 293s = ~2.2s/episode, well under per-subagent overhead).
- **Subagent mode (per spec §4.6, deeper context)** — `Task(subagent_type='reviewer-agent', prompt=<episode JSON + sanity-answers context>)`. Use for **N < 20 episodes** OR when the reviewer needs access to other tools (read related files, grep history). Per-episode try/catch — on subagent crash/timeout, fall back to `reviewViaDirectApi`.
Both modes write the same payload back: `review.*` + `outcome_reviewed` + `outcome_reviewed_source` (`direct_api_batch` for batch, `subagent` for Task(), `direct_api_fallback` when subagent fails). If both fail, leave `review.reviewer_error: <msg>` for the next retro.
6. **Aggregate** per `references/aggregation-template.md` — fill the Factor analysis matrix from the analyzer's `factorMatrix`, the task groups from `tasks`, the causal-chain candidates from `causalChains`, plus the new sections: sanity-check results, reviewer-agent outcomes distribution, self-retrospect trigger status.
7. **Propose candidates** — clearly separated section «Candidates for owner review». Each candidate has rationale + suggested edit + rejection-option.
8. **Save retro note**: `docs/observer/notes/YYYY-MM-DD-brain-retro.md` with full aggregation.
