Add validation checks before releasing:
- Ensure we're on the main branch to prevent accidental releases from feature branches
- Verify npm authentication to prevent failed publish attempts
This prevents common release mistakes and improves release workflow reliability.
Consolidate version bumping, building, npm publishing, and git operations into a single release script that handles platform packages first. This solves the issue where optionalDependencies needed platform packages published before bun install could generate complete lockfile hashes.
Changes:
- Created cli/scripts/release-all.ts with support for --dry-run, --publish-npm, and --skip-build flags
- Removed release-it dependency and old release/publish-npm scripts
- Simplified GitHub Actions release workflow to always use --generate-notes
- Deleted obsolete release configuration files (.release-it.json, .release-it.notes.js, publish-npm.ts)
