feat(#2306): plan-review-convergence v2 — CYCLE_SUMMARY contract, config gate, local model reviewers (#2718)

* feat(#2306): plan-review-convergence v2 — CYCLE_SUMMARY contract, config gate, local model reviewers

Fixes the false-stall detection bug in the plan→review→replan convergence
loop. REVIEWS.md accumulates history across cycles so raw grep inflated
HIGH counts; HIGH count now comes from a per-cycle CYCLE_SUMMARY contract
emitted in the review agent's return message.

Key changes:
- workflow.plan_review_convergence config gate (disabled by default, same
  pattern as workflow.code_review / workflow.nyquist_validation)
- Review agent prompt defines CYCLE_SUMMARY: current_high=<N> contract with
  PARTIALLY RESOLVED / FULLY RESOLVED counting rules
- Orchestrator aborts on absent/malformed CYCLE_SUMMARY (distinguishes both)
- Warns when HIGH_COUNT > 0 but ## Current HIGH Concerns section is missing
- Stall detection and --ws forwarding preserved and tested
- Local model reviewers: --ollama, --lm-studio, --llama-cpp flags added to
  convergence workflow and review workflow; all three use OpenAI-compatible
  /v1/chat/completions endpoint with jq --rawfile for safe JSON encoding
- review.ollama_host / review.lm_studio_host / review.llama_cpp_host config
  keys registered and documented (default to localhost:11434/1234/8080)
- review.models.ollama / .lm_studio / .llama_cpp model-name config support
- 58 tests (up from 29 in PR #2339), all passing

* fix(ci): sync sdk/src/query/config-schema.ts with CJS schema (#2306)

Add workflow.plan_review_convergence, review.ollama_host,
review.lm_studio_host, and review.llama_cpp_host to the SDK-side
TypeScript mirror — required by the CJS↔SDK parity test (#2653).

* fix(#2306): resolve CodeRabbit review findings

- Anchor HIGH_COUNT extraction with head -1 to prevent multi-match when
  agent return message contains multiple CYCLE_SUMMARY lines (e.g. quoted
  back from prompt context)
- Replace hardcoded reviewers list in REVIEWS.md frontmatter template with
  runtime-derived placeholder — the static list did not reflect which
  reviewers were actually invoked
- Broaden workflow.plan_review_convergence docs to include local reviewers
  (Ollama, LM Studio, llama.cpp) alongside cloud reviewers

* fix(ci): restore reviewers frontmatter list with runtime note

The cursor-reviewer.test.cjs (and equivalent per-reviewer tests) assert
that each supported reviewer appears on the reviewers: line — these are
wiring tests that catch when a new reviewer is added to invocation but
not to the REVIEWS.md template. Replacing the list with a placeholder
broke those tests.

Restore the full static list and add an inline comment clarifying that
the actual committed frontmatter should be filtered to only the reviewers
invoked that run — satisfying both the per-reviewer tests and the
CodeRabbit correctness note.
