feat(omo-claude): port ultragoal to per-session file-based goals

Goal content under ./.omo/ultragoal/sessions/claude-<id>/ keyed by Claude Code
session_id (claude: prefix); UltragoalScope struct threaded; plan version 2 +
index.json registry with read-only v1 forward-migration (never deletes v1);
create_goal/get_goal/update_goal dependency dropped (file/steering-based); the
PreToolUse create_goal budget guard kept compiled+unit-tested but its hooks.json
registration removed (inert in CC). 26 tests pass. ultragoal removed from
sync-components HANDLED set — it is a hand-fork, not patch-synced.
