v1.2.0

### Added
- **Claude Code plugin-marketplace support** (#45) — `.claude-plugin/plugin.json` + `marketplace.json`; install with `/plugin marketplace add 0xNyk/council-of-high-intelligence` then `/plugin install council@council-of-high-intelligence`. Root `SKILL.md` remains the single source of truth via a `skills/council/` symlink; a new Asset Resolution section resolves agents/scripts/configs from either the install.sh layout or `${CLAUDE_PLUGIN_ROOT}`.
- **Confidence-weighted vote tally** (#44) — a member's vote weight is now base weight (1.0, or 1.5× domain seat) × confidence factor from their `STANCE:` line (`high 1.0 / med 0.75 / low 0.5`). `W_total` stays at full base weights, so a hesitant council raises its own consensus bar and escalates to the user rather than forcing a verdict (Roundtable Policy, arXiv:2509.16839; ConfMAD, arXiv:2509.14034).
- **Per-member `reasoning_method` frontmatter** (E3 / DMAD, arXiv:2410.12853) (#44) — all 18 personas declare a distinct reasoning method (elenchic-questioning, tail-stress-testing, causal-loop-mapping, …) and Round 1 prompts direct each member to reason via their method: method diversity, not just persona diversity.
- **Project-level `./.council.yaml` overrides** (E7) (#44) — pin `profile`/`triad`/`members`/`chairman`/`models`/`no_auto_route` per project; CLI flags always win.
- Standard repo furniture (#42) — `.gitignore`, `SECURITY.md`, `FUNDING.yml`, bug/feature/provider issue templates, and a PR template with a three-file protocol-parity checklist.
- **Structured stance voting + deterministic weighted tie-break.** The final round (full Round 3 / quick Round 2) now requires each member to emit a machine-parseable `STANCE: <option> | CONFIDENCE: … | DEALBREAKER: …` line, so consensus is a counted weighted tally rather than a prose impression. STEP 6 specifies the exact math: `W_option ≥ (2/3) × W_total`, with the on-domain seat carrying 1.5×. New **Vote Tally** field in the full and quick verdict templates records `option → weight` and which seat carried the weight. Mirrored in `SKILL.codex.md`.
- Cursor CLI provider support (`cursor_cli` archetype) — sixth dispatch path alongside subagent / codex_exec / gemini_cli / ollama_run / openai_compatible_api. Auto-detected via the `cursor-agent` binary; members run headless and read-only (`cursor-agent -p --mode ask --model <id>`). Cursor is a model aggregator (GPT-5.x / Claude / Gemini / Grok through one CLI), so routing treats it as a single provider for spread and steers diversity seats to cross-family models to avoid duplicating Anthropic bias. New `configs/provider-model-slots.cursor.example.yaml`, `cursor_cli` tiers in `configs/auto-route-defaults.yaml`, and `cursor_cli` as a valid `--chairman` tag.

### Changed
- **Domain-weight seat (1.5×) is now designated at panel selection (STEP 0), before any positions exist** — previously chosen at tie-break time, which let the coordinator pick the heavyweight after seeing votes. Locking it up front removes that nudge.
- README "Enforcement Mechanisms" rewritten to state the actual forcing function (bounded round budget + anti-recursion guards) and that genuine splits escalate to the user instead of being forced into consensus.
- **CI drift guards are now real** (#42) — `council-simulation-checklist.sh` executes in CI (it never ran before), extended with full `SKILL.gemini.md` parity checks and a three-file STANCE/Vote-Tally/1.5×/2-3-threshold parity gate; markdownlint's variadic `--disable` was missing its trailing `--` and silently linted zero files — rule selection now lives in `.markdownlint.json` and covers all doc files.
- `install.sh` derives the generated `gemini-extension.json` version from CHANGELOG instead of a hardcoded string; model IDs reconciled across configs/docs (`gemini-3-pro`, `gpt-5.4` generation); README/CLAUDE.md document the `--gemini` install path and marketplace install.

### Fixed
- **`SKILL.gemini.md` drift regression** (#42) — the Gemini coordinator was missing structured stance voting, the weighted 2/3 tie-break, and the Vote Tally verdict field entirely; `SKILL.codex.md` referenced a Vote Tally field its own verdict template lacked.
- `SKILL.md` `classic` profile said "All 11 members" — the roster is 18 (#42).
- Shell-injection surface in external dispatch templates — prompts now route through quoted heredocs instead of being inlined into double-quoted argv; API keys no longer appear in `ps`-visible curl argv (#42).
- Tracked `.DS_Store` and a stray `.gstack` error log removed; junk excluded from release tarballs (#42).
