chore(fable-mcp): bump version to 0.2.6 for briefing introspection tools

Manual bump because the pre-commit hook that normally handles this
didn't run — its scripts had lost their executable bits earlier in
the session. Permissions have been restored in this commit's tree,
so subsequent commits touching fable-mcp will auto-bump again.
