v4.1.7

"Docs for a Studio": the plan's sixth release, the last before 4.2; the documentation a studio reads
first, after the code it describes. What this release does not do is in the LOG and the passes sheet.

Changes

• Docs for a studio (4.1.7, the plan's sixth release). The READMEs rewritten in both languages: one pitch,
  three commands, what each role gets, the screenshots taken again from the current build, one table of numbers,
  the current release in one paragraph (the release-by-release stack is the CHANGELOG's), a non-affiliation note
  (also in CREDITS.md). docs/en/TUTORIAL.md and its French twin: a first room in fifteen minutes. API.md carries
  the public API's signatures, generated from the sources (tools/api-doc.ts, held by tests/api-doc.test.ts).
  SUPPORT.md says the 4.1.x policy once and has a support matrix (what CI checks, what only people check). STUDIO.md
  in French has the three sections it summarised (Assets, Demo, Assistant); a test keeps every French page within a
  third of its English twin, section by section; another checks every relative link in the docs. AGENTS.md loses
  the rules of the pair work that ended with v3; CLAUDE.md points at the right pages. The release notes drop the
  work log's entry and decision numbers. CODE_OF_CONDUCT.md, a pull request template and a feature issue template;
  the wiki is off. Fixed: a warm-up of the assets in progress ended with App.destroy() neither its idle waits
  nor its fetches (CI's node-24 saw window is not defined from a test's torn-down page); the bank now carries the
  player's abort signal and stops at it. The first visit's JavaScript goes from 122 to 123 KB gzipped for it (the
  baseline moved on purpose; the budget, initialJsKB 140, is untouched).

Manual passes (D12: reported, not blocking)

10 of 14 done.

Pass	Status	Who, when	Device, OS, browser, versions	What failed

4	SUPPORT.md has one "exception" per release and no matrix	the 4.1.x policy said once; a support matrix of what CI checks and what only people check
5	a French page summarises what the English one explains	STUDIO.md complete; every French page within a third of its English twin, section by section (tests/docs-truth.test.ts)
