fix(ci): scope LOC check to studio, split useTimelinePlayer + hyperframes-player under 500 LOC (#750)

* refactor: split useTimelinePlayer.ts and hyperframes-player.ts into focused modules (<500 LOC each)

* fix(ci): scope 500 LOC check to packages/studio, add allowlist for grandfathered files

* feat(cli): Linux ARM64 support — auto-install Chromium on DGX Spark / GB10 / Jetson

Chrome Headless Shell has no Linux ARM64 binary. On arm64 Linux:
- Detects the platform automatically
- Tries to auto-install system Chromium via apt-get (works on Ubuntu/Debian ARM)
- Falls back to clear manual instructions with exact commands
- 'hyperframes browser ensure' guides through the setup interactively
- After setup, all render commands work without any flags

* fix(ci): disable Windows Defender real-time monitoring to prevent EPERM builds

Path exclusions are insufficient — Defender re-scans new files created
during bun install before the exclusion takes effect. Disable real-time
monitoring for the entire job duration instead (standard CI practice).

* refactor(studio): split all files >500 LOC + extract useToast, delete allowlist

All 11 large files split into focused modules under 500 LOC.
App.tsx extracted toast logic into useToast hook (493 LOC now).
.filesize-allowlist deleted — no longer needed.

* fix: remove unused imports from split files, extract useToast from App.tsx

App.tsx: 504 → 493 lines (toast logic extracted to useToast hook)
timelineDOM.ts: remove unused imports from re-export pattern
MotionPanel.tsx: remove unused clampStudioCustomEasePoints import
studioMotionOps.ts: remove unused StudioGsapMotionDirection import

* fix(ci): use Set-MpPreference to fully disable Windows Defender (both jobs)

* fix(producer): use node --experimental-strip-types instead of tsx for build:fonts

Eliminates the tsx binary dependency that Windows Defender locks during
bun install, causing EPERM errors. Node 22.6+ strips TypeScript types
natively with no external binary.

* chore: remove .filesize-allowlist — App.tsx is now 493 lines (<500)

* fix(ci): disable Windows Defender before checkout to prevent all EPERM races

* fix(producer): skip build:fonts if fontData.generated.ts already exists

The generated file is tracked in git, so CI doesn't need to regenerate
it. This avoids @fontsource/inter node_modules access on Windows which
triggers EPERM from Defender scanning during bun install.
