fix(ci): use bun for wrangler deploy and drop stale package-lock.json

The wrangler-action auto-detected the committed package-lock.json and
ran npm, which failed on an eslint peer-dep conflict. Remove the stale
lockfile, gitignore non-bun lockfiles, add wrangler as a dev dependency
so the action reuses the local install, and pin packageManager: bun.
