chore: ignore Task cache directory

Task (used by wails3 via Taskfile.yml) stores incremental-build fingerprints under .task/checksum/. Purely local cache — hashes of sources/deps, machine-generated, recreated on next wails3 dev/build. Keep it out of git like node_modules/frontend/dist/build/bin (already ignored). No files were tracked; this just stops it showing as untracked on branches that have run wails3.
fix(ci): track frontend lockfile for reproducible installs
