fix: sync claude-code-config with renamed/removed skills and clean broken symlinks

The skills config in core/claude-code-config.json was never updated after
commit 151c4fe renamed and removed several skills. This caused
`smartem-workspace check --fix` to report missing skills and fail to create
symlinks for targets that no longer exist.

- Rename database-admin -> database
- Rename technical-writer -> tech-writer
- Rename playwright-skill -> playwright
- Remove github (merged into git)
- Remove ascii-art (deleted)
- Sync bundled copy in packages/smartem-workspace/

Also enhance check.py to detect and remove stale broken symlinks under
.claude/skills/ during --fix. The cleanup is constrained to entries that
are (1) symlinks, (2) whose target does not exist, and (3) whose name is
not in the expected skills list -- so user-created skills and valid
symlinks are never touched.

Bump smartem-workspace version 0.6.0 -> 0.6.1.
