Per-family capability gates now use a name-to-flag table instead of matching skill and tool name strings.

The helper for checking per-family capability gates no longer relies on heuristic string matching against skill/tool names. It now looks up a table mapping local names like per_turn_effort to remote flag names like tengu_per_turn_effort and queries featureGateLookup directly.
