docs: sync after #466 (E2E catalogue Teile count)

[Sev7eNup]

What & why

Daily documentation-drift sweep over the PRs active between 2026-10-03T01:03Z and
2026-10-04T03:03Z. One clear, objective drift was found and is fixed here.

Doc surface	Change	Caused by
src/nodepilot-ui/e2e/README.md	The catalogue is introduced as 86 Teile instead of 85	#466

#466 appended Teil 86 ("Geführte Aufgaben der Browser-Demo") to
docs/testing/E2ETests.md, which now carries 86 contiguous Teile (1–86). The coverage
map's intro sentence still named 85. DocumentationCountsTests pins the MCP tool,
activity, skin, vitest, e2e-spec and doc-site-page counts, but not this one, so CI had
nothing to catch it with.

No row was added to the coverage table: Teil 86 covers e2e-demo/ specs, which the
README deliberately keeps out of the table ("The browser demo has its own suite, in
e2e-demo/ rather than here") — the same way Teil 85 is handled.

How

A one-word count correction. Nothing else in the window required a doc edit:

• Migrate to Quartz 4.2.1 #467 (Quartz 4.2.1) — the removal of summary from GET /api/triggers/schedule/next-fires,
  np cron next and the MCP validate_cron tool is documented nowhere, so no surface went
  stale; the PR updated the maintenance-window line in docs/claude-reference.md itself. The
  docs-site gap for the new DST and cron-parsing semantics is already tracked in PR-Review #467: Quartz 4 changed when schedules fire, and the documentation website does not say so #473 and is
  deliberately not duplicated here.
• Update the desktop shell to Electron 44.4.5 #470 (Electron 44.4.5) — no doc surface names an Electron version; the pin lives in
  package.json and package-contract.test.ts.
• Fix the runspace cancellation grace period so it actually fires #465 (runspace cancellation grace period) — the constant is internal and undocumented.
• Bump the npm-minor-patch group across 1 directory with 5 updates #464 / Bump the npm-minor-patch group across 1 directory with 13 updates #459 / Bump the actions-all group with 2 updates #457 — minor/patch dependency bumps, no documented version claims affected.
• Bump electron from 43.7.6 to 44.4.5 in /src/nodepilot-desktop #441 / Bump Quartz and Quartz.Extensions.Hosting #445 / Bump the npm-minor-patch group across 1 directory with 4 updates #442 / Fix the remaining CI flakes: redactor fail-open and tight test budgets #468 — closed unmerged (superseded).
• Release 1.4.4 #471 — open; its own CHANGELOG entries are its work, not drift.

Two findings were deliberately not auto-applied and are filed as issues instead.

Testing

Documentation only — no code, no test behaviour changed. The guarded counts were
re-derived by hand against the guard formulas and all match
(e2e specs 77, vitest files 242, docs-site EN pages 45).

• Guard/parity tests run for whatever this change touches — DocumentationCountsTests
  does not cover the N Teile claim; the figures it does cover were verified unchanged
• CI covers the rest (DocumentationCountsTests runs on every PR — Markdown is a
  backend input, so the backend job is never skipped)

Checklist

• Branched off main; no direct commits to main
• Docs updated
