chore(sync): merge upstream product through v0.0.36

[aaditagrawal]

What changed

Merge the upstream release train through v0.0.36 on top of #247. This layer integrates the newer product and provider behavior, including Grok/ACP reliability work, while preserving the fork's richer shared ACP runtime.

The adapted shared ACP layer retains runtime modes, model metadata, approval memory, liveness monitoring, plan events, and the fork's complete built-in provider set.

Verification

• node_modules/.bin/vp check
• node_modules/.bin/vp run typecheck
• Full repository test suite on the integrated stack: 933 files passed, 3 skipped; 9,698 tests passed, 26 skipped
• Focused Grok and shared ACP tests
• Integrated provider-settings QA on the completed stack

Mobile native verification is delegated to hosted CI because this machine has neither a usable Xcode installation nor an Android emulator.
