Merges upstream pingdotgg/t3code main into the fork's main: 267c90831a..47f2c8d29e from upstream's side (23 upstream commits, through pingdotgg#29169).

Conflicts

None. The merge was clean.

Fork adaptations

• Runner audit (fork_ci_audit.py --rewrite-runners --prefix T3CODE) found no new hard-coded runner labels.
• No new github.repository == 'pingdotgg/t3code' guards. The count is unchanged at 17.
• Upstream ci(release): preview releases run from any branch pingdotgg/t3code#27828 changed release.yml so preview releases run from any branch (the environment is now empty for preview, and Clerk/relay ids come from .env.example). This doesn't affect the fork's nightly path. The fork's T3CODE_RELEASES gate, UPSTREAM tracing skip and installer repository rewrite are all still there.
• The merge didn't touch any per-project git account files (gitAccounts, ProviderSessionManager, ProviderTurnStartService, GitManager, terminal Manager, PullRequestService, MCP project toolkit). It also didn't touch the release-repository files (cliRelease.ts, public-config.ts, npmRelease.ts).

Verification (Windows)

• vp run check:changed: format, lint, knip, graphql, typecheck (39 packages) and react compiler all pass. The test step hit the local 900s timeout and is being re-run with a longer one. CI runs the full suites.
• Fork suites, apps/server (src/gitAccounts, terminal Manager, cloud npmRelease, PullRequestService, src/mcp/toolkits/project): 9 files, 255/255 passed.
• Fork suite, apps/web GitAccountsSettings.browser.test.tsx: 2/2 passed.
