Partial fix for the lockfile drift caught in the audit. The previous
session ran `npm install` inside web/ as a workaround for a Vite vendor-
resolution issue, which left three lockfiles in the wrong places:
- web/package-lock.json (npm artifact in a pnpm monorepo)
- web/pnpm-lock.yaml (per-package pnpm lockfile, also wrong)
- backend/pnpm-lock.yaml (same issue)
This commit:
- Deletes those three files from the working tree.
- Adds .gitignore entries so they can't be re-committed by accident.
- Also gitignores .claude/ (Claude Code session metadata).
What's still missing: the root pnpm-lock.yaml needs `react-router-dom`,
`@monaco-editor/react`, `@dnd-kit/{core,sortable,utilities}` added to
its resolution graph. That requires `pnpm install -r --no-frozen-lockfile`
from the repo root on a workstation with GITEA_NPM_TOKEN exported (the
mobile workspace pulls @bytelyst/* private packages from the org's
private registry; this session has no token so the install errors out
on the mobile resolve). It's a one-line follow-up — tracked in
AUDIT_REDESIGN.md item E2.
