fix: resolve stash conflict markers in AGENTS.md, zopu.ts, package.json, bun.lock

All four files had unresolved git stash-pop conflict markers baked in.
- AGENTS.md: keep ours (docs/ canonical reference)
- zopu.ts: keep ours (authenticatedAgentRoute)
- package.json: keep ours (catalog: convention)
- bun.lock: restore clean version from pre-damage commit
