docs: add Mar 20-21 session learnings and expand token refresh finding

Reviewed 5 JSONL sessions from March 20-21:
- 455cf1db: Mar 19 learnings extraction (already captured)
- 44ae2b94: Nightly report #15 generation (already captured)
- 678ad961: PRD creation for fix_common_patterns.py (tasks/prd-compound-2026-03-20.md, 15 stories)
- 91e87a20: Ralph conversion to prd.json (branchName ralph/fix-common-patterns-2026-03-20)

New CLAUDE.md finding: daytona_runner.py:220 and daytona_poc_runner.py:197
also only catch HTTPError in token refresh (same bug as claude_baseline_agent.py:1523).

Also notes nightly #15's recommended feature (CI test gate + abc_audit fix)
has no PRD yet — distinct from the fix_common_patterns.py PRD created this batch.

 - **Runner cleanup**: No `trap` for temp dirs. `mktemp` failure (line 648) silently copies to CWD.
