feat(miner-config): parse a feasibilityGate policy block from .gittensory-miner.yml (#4275)

[davion-knight]

Adds a feasibilityGate field to MinerGoalSpec so a maintainer can tune the miner feasibility gate per repo, extending the existing tolerant .gittensory-miner.yml parser (packages/gittensory-engine/src/miner-goal-spec.ts).

Design

• A policy block, not a scalar — feasibilityGate is an object (so it can grow), today carrying a single field: suppressReasons, the feasibility-verdict avoid/raise reason codes the gate should ignore for this repo. Default: an empty block (suppress nothing). This implements the "suppress specific avoid/raise reasons per-repo" option the issue names.
• Wired exactly like the existing six fields: a normalizeFeasibilityGate helper (reusing normalizeStringList for suppressReasons, degrading a non-object/list value to the empty block with a warning, never throwing), the DEFAULT_MINER_GOAL_SPEC entry + deep clone, and hasConfiguredGoalFields (so a spec that sets only feasibilityGate is still detected as present).
• Deliberately does not touch the non-exported miner-goal-spec-parse.ts sibling (no real caller — per the issue's caution).
• Updates the JSON Schema mirror + docs/miner-goal-spec.md to match (kept in sync with the drift test), and re-exports the new MinerFeasibilityGatePolicy type from the package barrel.
• The gate's actual consumer is separate, maintainer-owned wiring (feat(miner-plan): wire the feasibility gate into a new MCP tool + miner CLI command #4270); this defines the config surface only.

Tests

New test/unit/miner-goal-spec-feasibility-gate.test.ts covers absent (default, bare spec stays not-present), a set block (marks present), suppressReasons de-dup/non-string skipping, and non-object + list degradation with targeted warnings — 100% branch coverage on the new code. Updated the engine's node:test contract/parser suites (exact field-surface + full-spec assertions) and the docs/schema drift test's field list; the whole engine suite (311 tests) and typecheck are green.

Closes #4275
