fix(mcp): use wrapper scripts instead of venv symlinks

Replace direct python path in .mcp.json with run.sh wrapper scripts
that automatically locate the venv in cache or local directory.

Problem: .venv symlinks are gitignored, causing them to be wiped on
every git operation. The SessionStart hook should recreate them but
this was unreliable, leading to repeated MCP server failures.

Solution: run.sh scripts that:
- First check ~/.cache/claude-mcp-venvs/leo-claude-mktplace/{server}/.venv
- Fallback to local .venv if exists
- Exit with helpful error if neither found

This eliminates dependency on symlinks entirely - the scripts are
tracked in git and will always be present after clone/pull/update.
