docs(plan): record #102 as closed by #203, and the run that exercised it

[quantecon-services]

Fixes a stale row in docs/dev/PLAN.md (a loose end listed in #212).

The #102 row in the disposition table still said to review #203 and to validate it with a maintainer dispatch after merge, and it called #144 open. Now:

• ci(lecture-validation): retry a failed HTML build once with --all; restore lecture-python-programming to the matrix #203 merged on 2026-09-28 and closed test-containers-lectures: absorb transient raw-GitHub 429s when building lecture repos #102, and Retry transient lecture HTML build failures #144 was closed unmerged.
• The weekly matrix run the same day, 36370003884, did the validation the row asked for:
  • Six of eight legs passed, lecture-python-programming on both images among them.
  • Both lecture-python.myst legs failed the retry on bayes_nonconj alone (numpyro 0.22). That is the retry working as intended: a persistent failure still fails the leg.
  • The fix belongs in lecture-python.myst (lecture-python.myst#1065). 🔴 CI failure: Test Container Builds #159 tracks the red matrix.

The row now says that, and its disposition becomes "—", like the other closed rows. The Last updated header gains an entry.

Only PLAN.md changes, so there is no changelog entry, as with #200. generate-docs.py --check passes and the table's cell counts are unchanged.

Copilot review overview

🟡 Changes recommended

The new row's (#159) reference points to this repo's CI-failure alert issue rather than the lecture-python.myst fix it claims "belongs in that repo," which is an accuracy nit in an accuracy-focused doc.

What changed in this PR

This PR updates a single stale row (and the running changelog header) in docs/dev/PLAN.md to reflect that issue #102 was closed by PR #203 on 2026-09-28, and that the weekly matrix run the same day validated the retry the row previously asked a maintainer to run. It is one of a series of documentation-accuracy PLAN.md updates (e.g. #200) and carries no code or CHANGELOG changes.

Changes:

• Rewrites the #102 disposition row from "Body superseded / Review #203 / validate after merge" to "Closed — fixed by #203", records the validating run 36370003884 (6/8 legs passed, lecture-python-programming on both images), notes both lecture-python.myst legs failed persistently on bayes_nonconj, and marks #144 closed-unmerged; disposition becomes "—" like other closed rows.
• Adds a new "Last updated" header entry noting the #102 row now records #203's closure and the matrix run.

File	Description
docs/​dev/​PLAN.md	Updates the #102 disposition-table row and the "Last updated" header to record #203 closing #102 and the 2026-09-28 matrix run that exercised the retry.
