[plan] Add cache-memory baseline pattern documentation for stateful analysis workflows #29786

Objective

Document the cache-memory baseline pattern for stateful analysis workflows (e.g., coverage tracking, metrics comparison across runs).

Context

From discussion #29782 — Agent Persona Exploration found that cache-memory is used well for stateful baseline comparison but this pattern isn't clearly documented for users building similar workflows.

Approach

1. Locate the appropriate documentation file (likely .github/aw/create-agentic-workflow.md or docs)
2. Add a Stateful Analysis with cache-memory section covering:
   • When to use cache-memory (tracking metrics across runs, comparing current vs. baseline)
   • How to store a baseline value (e.g., coverage percentage, metric score)
   • How to read it on the next run and compare
   • Worked example showing a coverage delta workflow:
     • Run 1: store baseline coverage to cache-memory
     • Run 2+: load baseline, compute delta, post comment if regression
3. Include a note on filesystem-safe filenames (no colons in timestamps — use YYYY-MM-DD-HH-MM-SS format)

Files to Modify

• .github/aw/create-agentic-workflow.md (or relevant docs file)

Acceptance Criteria

• cache-memory baseline pattern is documented
• Worked example shows store-then-compare across workflow runs
• Filename safety note included (no colons in artifact names)
• Example uses filesystem-safe timestamp format
