docs(devlog): close out unpriced-model overlay unit after PR #4444

[lidge-jun]

Summary

• Records the terminal outcome of the unpriced-model overlay sweep (PR feat(usage): register verified Z.AI GLM list prices as expected-cost overlays #4444, merged as 2bd8edf) in the devlog unit and moves the completed unit from devlog/_plan/ to devlog/_fin/ per the repository's devlog convention.
• Docs-only bookkeeping; no runtime, test, or workflow changes.

Verification

• Local suite NOT RUN (docs-only change; per session constraint all verification is hosted CI on the exact head).
• Rename-only diff: 6 files moved, plus the new 021_wp3_outcome.md (11 lines).
• Hosted CI on this PR's head is the verification gate.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

• Documentation
  • Added a roadmap and inventory covering 77 models with missing or zero pricing metadata.
  • Documented provider-specific pricing evidence, verification statuses, overlay registration decisions, and cases where pricing was unavailable or models were deprecated.
  • Added research records describing pricing-source findings and registration classifications.
  • Recorded the pull request workflow, hosted CI results, review feedback, and merge outcome.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use the correct Git commit term.

020_wp3_pr_merge.md records --squash. That operation creates a single squashed commit on dev, not a Git merge commit. Rename merge commit to squash commit or resulting commit so this terminal record matches the recorded merge mode.
