feat(goal): 4 new subcommands for issue #140 fusion (status/complete/subtask/report)

[Delqhi]

Implements 4 of the 8 tools from the external SIN-Code-Goal-Mode-Skill Python MCP server. The remaining 2 (goal_checkpoint + goal_rollback) are deferred to v1 because the Queue has no Checkpoint table yet.

What ships

• cmd/sin-code/goal_cmd.go — 4 new subcommands:
  • goal status <id> — show one goal with subtasks
  • goal complete <id> — mark a goal as verified/done
  • goal subtask <parent-id> <prompt> — add a subtask
  • goal report [--format md|json] — progress report
• cmd/sin-code/goal_fusion_test.go — 11 unit tests for parseGoalID
• CHANGELOG entry

Mapping to the 8 external tools

External tool	Native equivalent
goal_start	goal add (existing)
goal_status	goal status (NEW)
goal_list	goal list (existing)
goal_complete	goal complete (NEW)
goal_subtask	goal subtask (NEW)
goal_report	goal report (NEW)
goal_checkpoint	Deferred to v1 (no storage yet)
goal_rollback	Deferred to v1 (no storage yet)

6 of 8 tools are now native. The 2 deferred are documented in the CHANGELOG with a clear v1 migration path.

Hard mandates honored

• M2 (single binary): no new deps
• M3 (verify gate sacred): goal complete is the entry-point the stop-gate uses
• M7 (race-clean): 11/11 tests pass under go test -race -count=1
