ovecc 0.1.0

Initial public release.

Added

• ovecc init to scaffold .ovecc/config.toml, and ovecc index to build the
  model: tree-sitter + oxc parsing, import/call resolution, DuckDB persistence,
  incremental re-index (unchanged files are never re-parsed).
• ovecc capabilities: machine-readable contract listing every command, metric,
  rule, severity, exit code, and output format.
• Analysis commands: summary, impact, query, violations, security,
  audit (offline OSV), hotspots, dupes, health, deadcode, fix,
  diagnose, advise, metrics, conventions, diff, drift, history,
  gate, review, report, explain, export context, export graph.
• Code-smell detectors over the resolved call graph: feature envy, large
  class, and data clumps; counted by gate and named by review.
• ovecc mcp: Model Context Protocol server over stdio exposing every command
  as an agent tool.
• Drop-in GitHub Action (action.yml): indexes base and head of a PR, comments
  the named new defects, and gates on severity.
• Output formats: text, json, ndjson, markdown, plus sarif and
  codeclimate; stable exit codes for CI.
• Governance rules in .ovecc/config.toml: module boundaries, banned imports,
  severities, baselines, inline ovecc-ignore suppressions.
• Languages: JavaScript/TypeScript (tree-sitter + oxc resolution, complexity,
  exports); Python, Go, Rust, and C++ through a specification-driven adapter.
