chore: sync upstream pingdotgg/t3code

[wizzoapp]

Nightly sync of new commits from pingdotgg/t3code (3513fa04f..ecb35f758, 6 commits), cherry-picked because this fork squash-merges to main.

Synced commits

upstream	title
2fdc704bb	perf(web): duty-cycle status animations and remove fixed noise overlay (pingdotgg#3978)
7b928d548	fix(docs): correct CI task-runner commands in ci.md (pingdotgg#3990)

d359789ed	docs: Add T3 Code Legal Docs (pingdotgg#3972)
ecb35f758	Fix Legal modal header crash (pingdotgg#4000)

Conflict resolution

Exactly one file conflicted — docs/operations/ci.md (docs only; the rest of the range applied cleanly).

Upstream pingdotgg#3990 only rewrote the first bullet (bun run lint/typecheck/test → the Vite+ task-runner commands). The fork had independently diverged on the other bullets, so the hunk collided.

Resolution keeps the fork's description of the fork's real CI, and adopts upstream's corrected command names:

• Took upstream's command names — verified against .github/workflows/ci.yml: it really does run vp check (lint + typecheck), vpr typecheck, and vp run test. The fork's old text said vp run typecheck, which was stale.
• Kept fork-local reality for the remaining bullets. Taking upstream verbatim would have made these docs wrong for this fork: upstream claims macOS/Linux/Windows release artifacts, but release.yml here builds Windows x64 only (windows_signing: true, mobile builds deprecated). The mobile-deprecated and Windows-signing bullets are fork-local and were preserved.
• Also retained the fork's extra CI stages (desktop build verification, desktop launch smoke, release smoke).

Verification

• vp run typecheck — pass
• vp check — 0 errors (1 pre-existing lint warning in ConnectionsSettings.tsx, untouched by this sync)
• vp test run — 657 files / 5737 tests passed, 7 skipped

No prod-code changes were needed; the fork's model routing is registry-driven.
