chore(turbo): ingest upstream through v0.0.34-nightly.20260812.1072

[gfsaaser24]

Repairs nightly sync run 31552658971 using the merge-ingest pattern (#53, #66): merges pingdotgg/t3code main 560d4a456, which contains all 8 nightlies we were missing through v0.0.34-nightly.20260812.1072.

Seven conflicts, all resolved in the fork's favor with upstream as base

• themePalette: fork region roles now compose with upstream's new OKLCH pipeline — decodeThemeColors(withRegionThemeRoles(...)); the managed generator keeps its derived-region wrapper
• SidebarChrome: upstream's compact footer + PR/usage back buttons, with the fork's environment switcher above the menu
• ComposerPrimaryActions (+test): upstream's stage-artwork send button inside the fork's fixed PrimaryActionSlot (size-full — the slot owns the box, preserving the no-jump invariant); both test suites kept (16 pass)
• Mobile ThreadComposer: upstream's iOS settings menu and the fork's usage meters coexist
• BranchToolbar ×2: upstream's data markers and overflow classes

Also: pull-requests page now renders under chat panes

ChatPaneWorkspace painted panes over every child route; full-page children like /pull-requests changed the URL and nothing else. It now routes non-pane child routes through the outlet (isChatPaneTargetRouteId, unit-tested) — panes return when you navigate back to a thread.

Verification

• node scripts/turbo-customization-manifest.ts verify: 26 seams, 172 file checks pass
• Web suite: 2334 passed (255 files); reaper + settled suites pass; typecheck clean on web/t3/client-runtime/contracts/mobile
• Version line → 0.0.42
