fix: wire up Cursor integration in installer (#1605)

* fix: wire up Cursor integration in installer — was incorrectly marked "coming soon"

CursorHooksInstaller.ts was fully built but never connected to the
installer. Set supported: true in IDE detection and call installCursorHooks
in the setup flow, matching the pattern used by other integrations.

* fix: wire up Cursor MCP configuration during install

PR review flagged that the hint says "hooks + MCP integration" but
configureCursorMcp() was never called during install. Now invoked
after hooks install with graceful fallback if MCP setup fails.
