fix(release): add missing mandrel-mcp-th to publishing workflow

- Add Phase 7 to publish mandrel-mcp-th crate
- Fix mismatch between published crates (10) and validated crates (11)
- Ensures mandrel-mcp-th v0.4.3 is actually published to crates.io
- Resolves: 'mandrel-mcp-th version 0.4.3 NOT found' validation error

Root cause: mandrel-mcp-th was expected in validation but never included in publishing phases
