drop eight package.json scripts that point at nothing

Same origin as the phantom docs in the last commit — this architecture was based on another
project and some of its scripts came along without their targets.

- `build:editor` and its three variants run `scripts/build/editor.ts`, which has never
  existed here. CLAUDE.md carried a note saying exactly that, which the note now outlives.
- `start:sidecar` / `stop:sidecar` / `restart:sidecar` / `logs:sidecar` drive
  `systemctl … officer-pty-sidecar`, a systemd unit replaced by PM2. That unit still exists
  on this host, enabled, pointing at a `monorepo/` directory that is gone, and has been
  failing to start ever since — these scripts are how it stayed reachable.

CLAUDE.md's "Sidecar control" line pointed at the four systemd wrappers; it now says PM2 and
points at working-on-officer.md for which process a change needs restarted.

Verified afterwards that every remaining script's target exists. The rest of package.json is
untouched — the edit is nine lines out, no reformatting.

-Sidecar control: `bun run start:sidecar` / `stop:sidecar` / `restart:sidecar` / `logs:sidecar`.
+Sidecar control is PM2, not npm scripts: `pm2 restart officer-<name>`, `pm2 logs officer-<name>`.
+See `docs/working-on-officer.md` for which process a given change needs restarted.
 
 **Format your own files, not the whole dirty tree.** `bun format` globs `git diff --name-only HEAD`,
 so it rewrites every uncommitted file — including work in progress that isn't yours, which then shows
 up as unexplained whitespace churn in someone else's diff. Run `bunx prettier --write <paths>` on the
 files you actually touched. `bun format` is only safe when the tree is otherwise clean.
 
-Note: `build:editor*` in `package.json` points at `scripts/build/editor.ts`, which does not exist.
