Subject: [PATCH] fix(link-project): preserve project-specific .claude content
 when linking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously the script would backup and replace the entire .claude directory
with a symlink. This broke projects with their own .claude content (like
visa-ai with 76 immigration-specific config files).

Now the script:
- If project has existing .claude/ → only symlinks commands/ subdirectory
- If project has no .claude/ → symlinks entire directory
- Backs up existing commands/ to commands-local/
