ci: only run what a change affects, consolidate jobs (#3674)

* ci: only run what a change affects, consolidate jobs

- detect affected plugins from changed files and Cargo.lock dependency trees
- test/lint Rust per platform in shards instead of one job per plugin
- fold check-generated-files into lint-javascript, fmt into a single job
- skip fat LTO in integration test builds, single ABI in test-android

* ci: run e2e on bumps, use published tauri CLI, PR-safe pnpm cache

- trigger e2e on Cargo/pnpm lockfile and manifest changes
- install the latest 2.x tauri-cli with cargo-binstall in integration tests
- add setup-pnpm action: restore the store everywhere, save only on v2/v3

* fix clippy, ios build

* fix bumps [skip ci]
