v0.3.0

0.3.0 — Native pre-tool-use for Copilot CLI and VS Code

• agent-hooks enforcement surface: chock sync now writes .github/hooks/chock.json,
  the native pre-tool-use hook read by Copilot CLI and VS Code agent mode. Both honour
  exit 2 as deny (witnessed blocking on both). The hook resolves its interpreter at run time
  — skipping the Windows Store python3 alias stub that made hooks error — and finds the
  repo root with git rev-parse, so the committed file is portable with no baked path. One
  adapter now parses all three payload shapes (Claude, Cursor, Copilot/VS Code). Coverage is
  credited enforced for copilot/vscode only when the file is verifiably installed. Guards
  are bash-oriented, so on Windows PowerShell they catch bash-syntax commands but not
  PowerShell-native destructive syntax until a PowerShell guard ships (documented caveat).
