release: update LiteParse to 2.13.1

[Advait Paliwal (advaitpaliwal)]

Why

LiteParse 2.13.1 fixes table extraction that dropped in-table cells between established columns in multi-line headers. This directly improves paper and document reading.

Upstream evidence:

• LiteParse PR #420 merged as 2856997c018c04cfde568e306d40de0fa0ca9f61.
• Node release run 31996133977 published the wrapper and seven native packages.
• The synthetic fixture loses Detail, X, Y, and Z on 2.13.0 and preserves all four on 2.13.1.

What changed

• Pin LiteParse 2.13.1 across the wrapper, all seven native packages, runtime lock, and artifact verifier.
• Add source and installed-runtime regressions for the table-header cell-loss path.
• Update release notes and public release docs for Feynman 0.3.26.
• Load the native fixture through createRequire for Node 22 compatibility.
• Preserve es-module-lexer@2.3.1; no unrelated runtime dependency drift remains.
• Preserve the archived runtime package manifest and overrides during cross-Node reinstall.
• Reinstall all 13 archived exact packages plus new configured packages with --save-exact.

Node 22 repair

The first candidate run, 32007231665, failed its Node 22.22.0 consumer because the installed runtime silently resolved LiteParse 2.10.1.

The packaged archive had been built on Node 24. Node 22 rejected its ABI manifest, so patch-embedded-pi.mjs restored the archive. The installer then replaced feynman-runtime with only six fallback packages. That dropped the archive overrides and let pi-docparser install its old transitive LiteParse.

Commit 45bab8f fixes the owning installer instead of adding a consumer fallback.
