v0.1.0

Added

• Change-coupling indexer over git history: non-merge commits touching ≤ 30 files,
  Wilson lower bound scoring, alert floor 0.6, minimum support 10, incremental
  updates keyed by HEAD (.conventionsense/index.json).
• MCP server (conventionsense mcp) with five tools: check_holes,
  expected_companions, explain_rule, stats, reindex — every alert carries
  counts, confidence, and example commits as evidence.
• Pre-commit CLI: conventionsense check --staged (exit 1 at ≥ 0.7, configurable
  via --fail-at), plus stats and reindex subcommands.
• Per-repo configuration in .conventionsense/config.json; CLI flags override
  config, config overrides defaults.
• Content-aware exception layer for JSON triggers: learns which top-level keys
  ("facets") predict each rule and suppresses alerts for non-predictive edits
  (e.g. pure version bumps). Suppressed holes are excluded from the exit code;
  --strict re-includes them. Fail-open everywhere.
• Opt-in C# member-level detection ("memberLevel": true): members as entities
  (Namespace.Type.Member/arity, survives file renames), Roslyn syntax-only
  diffing, member holes in check_holes and the CLI, cosmetic-edit suppression
  (whitespace/comment-only C# edits), 5,000-commit training window.
• Packaged as a dotnet tool (ConventionSense, command conventionsense).

Notes

• Renamed from the working title "Lacuna"; the original spec document
  (lacuna-claude-code-prompt.md) keeps the old name as a historical record.
