chore(build): decommission embed-tfstate.mjs predev/prebuild hooks (#241)

Closes #164

## Summary

- Deletes `app/scripts/embed-tfstate.mjs` and removes the
`predev`/`prebuild` npm hooks that invoked it — the desktop app reads
tfstate directly at runtime via the AWS SDK, making the embed step
unnecessary
- Removes the `EMBEDDED_TFSTATE` fallback path from `ConfigService`
(including the generated `src/generated/tfstate.ts` artifact and
`.gitignore` entry for it) and updates the associated unit tests
- Cleans up stale references in `CLAUDE.md`, `package.json`,
`.github/workflows/package.yml`, `docs/`, and `scripts/init-parent.ts`

## Test plan

- [ ] `npm run app:test` — all unit tests pass (`ConfigService` tests no
longer exercise the embedded-tfstate path)
- [ ] `npm run app:lint` — 0 errors
- [ ] `app/scripts/embed-tfstate.mjs` no longer exists in the repository
- [ ] `app/package.json` contains no `predev` or `prebuild` scripts
referencing `embed-tfstate`
- [ ] `ConfigService` contains no reference to `EMBEDDED_TFSTATE` or
`src/generated/tfstate.ts`
- [ ] `npm run desktop:dev` starts without the embed step (no
`embed-tfstate.mjs` execution)
- [ ] `npm run desktop:build` completes without the embed step

 `ConfigService.getTfOutputs()` (in `app/packages/desktop-main/src/services/ConfigService.ts`) parses `terraform.tfstate` as JSON and caches it in-memory. `invalidateCache()` is called on `/api/games` and `/api/status` to pick up new deploys. The app's container mounts `./terraform:/app/terraform:ro` — this path coupling matters if directory structure changes. The parsed `TfOutputs` shape now also exposes `discord_table_name`, `discord_bot_token_secret_arn`, `discord_public_key_secret_arn`, and `interactions_invoke_url` so `DiscordConfigService` can reach the Discord stores without extra env-var plumbing.
 
-**Build-time state embedding**: `app/scripts/embed-tfstate.mjs` (runs via `predev`/`prebuild` hooks) writes `app/packages/desktop-main/src/generated/tfstate.ts`; `ConfigService` uses it as a fallback when the runtime `terraform.tfstate` is absent (Docker/CI). The file is committed as `null` and overwritten at dev/build time.
-
 ### API authentication
 
 Every `/api/*` route is gated behind a bearer token via `ApiTokenGuard` in `app/packages/desktop-main/src/guards/api-token.guard.ts`, registered globally in `AppModule` as an `APP_GUARD` provider so it applies to every controller automatically. The token comes from env `API_TOKEN` (wins, even when set to empty to deliberately disable) or `api_token` in `server_config.json`. In production (`NODE_ENV=production`), boot aborts in `main.ts` if no token is configured. In dev, a warning is logged and unauthenticated requests are allowed for convenience. The web client stores the token in `localStorage` under key `apiToken` and sends it as `Authorization: Bearer`. Don't remove the guard or bypass it on individual controllers — Copilot flagged the unauthenticated surface as a security issue and this is the fix.
