docs(parser): restore runParser documentation

[ClaudiuCeia]

Depends on #34.

• Moves the parser execution JSDoc back onto the exported runParser function.
• Leaves the private session helper undocumented so generated declarations expose the guidance at the public API.

Validation: bun run check, deno task check, bun run build, and bun run package:check.
