fix(build): remove zlob default feature to eliminate Zig compiler dependency

The zlob feature in fff-search requires Zig compiler at build time,
which is not available in CI/CD environments (Docker, cross-compilation,
crates.io publish). This caused build failures across:
- Docker multi-arch builds (Ubuntu 20.04)
- aarch64 cross-compilation
- crates.io publish verification

Remove zlob from default features in:
- terraphim_file_search (default = [])
- terraphim_middleware (remove explicit zlob feature)
- terraphim_mcp_server (default = [])

The non-Zig fallback provides identical functionality with slightly
reduced glob matching performance - acceptable tradeoff for CI reliability.
