Fix cleanup plan local worktree signals

[chubes4]

Summary

• Let retention cleanup planning run local worktree merge/remote-clean signal detection instead of inventory-only metadata classification.
• Update the human cleanup-plan label so operators can see that retention planning uses local worktree merge signals while still skipping artifact scans by default.
• Add a smoke assertion that a clean active remote-backed worktree is promoted into cleanup-plan removal rows instead of falling through to active/no-signal resolver rows.

Testing

• php tests/smoke-worktree-cleanup-cli.php
• php -l inc/Workspace/WorkspaceCleanupPlan.php
• php -l inc/Cli/Commands/WorkspaceCommand.php
• php -l tests/smoke-worktree-cleanup-cli.php
• php -l tests/smoke-worktree-cleanup.php
• php tests/smoke-worktree-cleanup.php currently reports 152/161 passed; the new cleanup-plan assertion passes, while existing duplicate dirty/external skip-count expectations still fail outside this change.
