Local Build Check

Catch and fix docs build errors before Netlify does using the Snooty RST parser.

When NOT to use

• Changes are entirely in code-example-tests/ → use Grove skills instead.
• Changes are entirely in platform/ → stop immediately and tell the user verbatim: "The local build check covers content/ only. For platform/ changes, run pnpm typecheck and/or pnpm lint in the platform/ directory instead." Do not invoke the skill.
• The user just wants a content review, not a build check.

Example interaction
