httpx2 migration revived, workflow payloads encrypted in vercel-py

vercel-py is porting to httpx2 and encrypting workflow payload writes, while chat fixes its stalled release pipeline and a CSS sourcemap bug lands in Turbopack.
vercel-py revived its migration to httpx2 [1], which stalled because respx does not support httpx2 yet. The fix vendors respx 0.23.1 and search-and-replaces it to httpx2, avoiding runtime monkeypatching or typing stubs. Separately, workflow payload writes are now encrypted and external hook resumes are sealed to the run's public key [2]; streamed data is not encrypted yet. The change also publishes a synthetic workflowCoreVersion, which the JS SDK uses (improperly) for capability detection.
The chat release pipeline has failed on every run since Sep 3 [3], so no package version has been published since then. The cause is a dependency mismatch from a Dependabot bump: the Changesets GitHub Action went from v1.9.0 to v2.1.1 but @changesets/cli stayed on v2. The fix restores releasing. chat also added button tooltips and a card width hint [4]; Teams renders them, and every other adapter leaves the card unchanged.
In next.js, Turbopack CSS sourcemaps always used index 0 for all source file references [5], producing misleading mappings when CSS comes from multiple sources. The fix corrects the source field. On the runtime side, dynamic access tracking was incomplete in final runtime prerenders [6]; the fix from #95665 only fired dynamicAccessAbortSignal during the prospective prerender, not the final one, so cache-key encoding missed dynamic accesses. The new change tracks them in both phases.
Action items
- → Upgrade vercel-py to a build containing the httpx2 port and encrypted payload writes if you depend on either feature vercel/vercel-py [monitor]
- → Check chat's release pipeline once the fix ships to confirm package versions resume vercel/chat [immediate]
- → Re-test CSS sourcemaps in Turbopack after the fix lands vercel/next.js [plan]
