docs(bf-9d8a5): update CLAUDE.md - bf close --reason now works

Remove stale workaround about bf close being broken. Updated:
- CRITICAL: how to close a bead - restore standard bf close workflow
- Doing the work step 6 - use bf close instead of bf batch
- What NOT to do (anti-loops) - removed obsolete section about bf close bug

The bf close command now works correctly as of 2026-05-26 verification.

 ## CRITICAL: how to close a bead
 
-**`bf close <id> --reason "..."` is BROKEN** in the current `bf` binary — it returns `Error: Query returned no rows` for every bead, including freshly-created ones. This is a bf bug, not a workspace problem.
+Close beads with `bf close <id> --reason "..."`:
 
-**Use `bf batch` instead:**
 ```bash
-bf batch --json '[{"op":"close","id":"pdftract-XXX","reason":"<one-line summary referencing commits/notes/test results>"}]'
-# Expected output: [op 0] ok
+bf close pdftract-XXX --reason "Implemented feature X. Closes pdftract-XXX. Verification: notes/pdftract-XXX.md, commit abc123. Tests: PASS (criteria A, B), WARN (infra issue C)."
 ```
 
 The `--reason` should be substantive: cite the git commits you made, the path to the verification note you wrote, the test fixtures you exercised, and any WARN/PASS items in the acceptance criteria. The reason is the only durable record of *why* you closed; treat it as the close commit message.

 5. **Commit** with a Conventional Commits message: `<type>(<bead-id-tag>): <summary>` — body cites the bead, lists the artifacts produced

 7. **Flush** via `bf sync --flush-only`
 
 If acceptance criteria contain WARN items due to environmental issues (missing CLI tools, transient infra, etc.), document them clearly in the close reason and the verification note. The bead may still close if the WARNs are infra-related and out of scope. PASS the substantive criteria; WARN the infra ones; FAIL only true blockers.

-## What NOT to do (anti-loops)
-
-The worker that ran before YOU did this loop and wasted hours:
-- Claimed `pdftract-1wqec` → did real verification work → tried `bf close --reason` (FAILED with Query returned no rows) → bead reverted to open via mend strand → re-claimed → repeat × 20
-
-If `bf close` fails on you, DO NOT just retry the same way. Try `bf batch --json` instead. If that ALSO fails, surface the failure and stop — don't burn cycles in a futile loop.
