Revert package source rescue primitive

[kentcdodds]

Summary

• Remove the package source rescue primitive that was merged/deployed in Add package source rescue workflow #530.
• Delete the MCP capability, repo-session RPC/DO recovery path, source rescue types/tests/audit writer, and publish-note extension.
• Remove the source-rescue table creation migration from the branch and add 0040-drop-source-rescue-events.sql so deployed environments drop source_rescue_events safely.

Testing

• npm run validate — passed on the same final tree.
• Note: the first full validate run hit an MCP E2E timeout while checks were running concurrently; npm run test:mcp passed standalone, then a subsequent full npm run validate passed.

📝 Walkthrough

Walkthrough

This PR removes the source-rescue feature entirely: the database table and indexes, the recoverSourceFromSessionCheckpoint RPC/durable-object method, the MCP package_source_rescue capability, the insertSourceRescueEvent module, related type definitions, and all supporting tests.

Changes

Source Rescue Feature Removal

Layer / File(s)	Summary
Database Table Removal packages/worker/migrations/0040-drop-source-rescue-events.sql	New migration adds DROP TABLE IF EXISTS source_rescue_events to remove the persisted events table.
RPC and Durable Object Method Removal packages/worker/src/repo/repo-session-do.ts, packages/worker/src/repo/repo-session-rpc.ts	Remove the recoverSourceFromSessionCheckpoint(...) method from both RepoSessionBase durable object and RepoSessionRpc type; clean up type imports for SourceRescueResult and inline publishedBy as a string literal union instead of imported type.
MCP Capability Exposure Removal packages/worker/src/mcp/capabilities/packages/domain.ts	Remove sourceRescueCapability import and reference from the packagesDomain capabilities array.
Type Contracts and Validation Updates packages/worker/src/repo/publish-git-notes.ts, packages/worker/src/repo/types.ts	Narrow KodyPublishGitNotePublishedBy union to remove 'source_rescue' option and update schema validation accordingly; remove SourceRescueValidationResult and SourceRescueResult type definitions; add repairHint: 'repo_rebase_session' field to RepoSessionPublishResult rebase outcome variant.
Test and Reference Cleanup packages/worker/src/repo/repo-session-do.node.test.ts, packages/worker/src/repo/source-safety-policy.node.test.ts	Remove insertSourceRescueEvent from shared mock module, baseline fixture initialization, and module-level vi.mock wiring; delete test case asserting recovery restores missing source HEAD; remove test verifying overwrites stay blocked without verified backup.

Poem

🐰 The source rescue sailed away today,
Its table dropped, its methods gone astray,
No RPC calls, no MCP to play—
Clean code hops forward, a brighter way! 🌿
