Replace the legacy webpack + tsc + shelljs build pipeline with Bun-native
equivalents throughout the monorepo.
- Add `packages/scripts/src/commands/build.backend.ts`: new backend build
script using `Bun.build({ target: "bun" })` — bundles app.ts to a single
`build/backend/app.js`, copies the env file, and installs only the two
native-module externals (saslprep, @ngrok/ngrok)
- Fix `packages/backend/src/app.ts`: replace `require.main === module` with
`import.meta.main` so the server starts correctly from the bundled ESM output
- Replace shelljs with `Bun.$` in build.util.ts; make file-check async via
`Bun.file().exists()`
- Remove the `build` CLI subcommand entirely — web uses `bun run build:web`,
backend uses `bun run build:backend`; strip the dead build.ts, build.util.ts,
webpack.config.mjs, and tsconfig.build.json
- Collapse cli.validator, cli.types, cli.utils, cli.constants to remove all
build-specific option parsing and package list constants
- Drop `shelljs`/`@types/shelljs` from scripts package.json and `concurrently`
from root package.json
- Update deploy.md and cli-and-maintenance-commands.md to reflect new commands
and output paths (build/backend instead of build/node)

Bun loads .env from the working directory, not the script's location. The runtime tip and deploy docs now reflect the correct invocation. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
