fix: skip macOS framework lookup in dev mode via build.rs

Use CARGO_MANIFEST_DIR to detect whether CI-copied dylibs exist.
When absent (local dev), override frameworks to empty array so
tauri dev doesn't require libodbc/libltdl installed locally.

Also gitignore *.dylib in src-tauri/ to prevent accidental commits.
