Add a new exporter

Follow this recipe to add an agent exporter without guesswork.

Steps

1. Create the module
   • Copy the smallest existing exporter as a starting point (e.g., packages/exporters/src/cline).
   • Add manifest.json and index.ts under packages/exporters/src/<agent>/.
   • Register it in packages/exporters/src/registry.ts.
2. Wire outputs
   • Decide output paths and filenames; keep them deterministic.
   • Include fidelity notes if the format is lossy compared to IR.
3. Add tests
   • Golden determinism: IR fixture → expected files in packages/exporters/tests/__fixtures__/<agent>/.
   • Contract coverage: validate manifest and hash stability if applicable.
   • Run: pnpm --filter @aligntrue/exporters test.
4. Docs
   • Add the agent to apps/docs/content/04-reference/agent-support.md with any fidelity notes.
   • Update CHANGELOG.md under “Added”.
5. init detection (optional)
   • If the exporter should auto-detect on aligntrue init, hook it into the detection logic in packages/cli/src/commands/init.ts.

Checks before opening a PR

• Golden fixtures pass for the new exporter.
• Manifest fields and outputs are documented.
• pnpm check and pnpm --filter @aligntrue/exporters test are green.
• Docs updated for user-facing behavior.
