## Summary by cubic
Adds reference documentation for the `onToolsAdded` and `onToolsRemoved`
hooks for TypeScript, Python, and Go, and removes the docs test
exception that previously skipped coverage for these hooks.
- Documents the subscription lifecycle, tool identity rules, and
callback signatures for `page.onToolsAdded()` and
`page.onToolsRemoved()`.
- Updates the WebMCP reference page to link to the new `onToolsAdded()`
docs.
- Removes `page/on-tools-added` and `page/on-tools-removed` from the
unreleased reference methods set so the SDK surface test now requires
these headings on every language page.
