Merge upstream: server self-update, thread branch drift fixes, sidebar refresh

[jetblk]

Brings in 5 new commits from pingdotgg/t3code main (main..upstream/main), evaluated per the fork's upstream-merge workflow. Full merge (no cherry-pick) to keep the RPC contract in sync between fork servers and upstream desktop/mobile clients.

Commits merged

Commit	Summary
2d31cb022 (pingdotgg#2284)	Prevent silent thread branch drift + better PR fetching
ab4a88386 (pingdotgg#4286)	Remote server updates + standalone service management (adds serverUpdateServer RPC, selfUpdate, service CLI)
593289c3c (pingdotgg#4268)	Refine light-mode sidebar surfaces (web + mobile)
78a0ea55c (pingdotgg#4275)	Copy branch name via right-click in the branch selector
bc9428a06 (pingdotgg#3949)	Mobile: don't mark Android VPN/Tailscale as offline when connected

Conflict resolution

One mechanical conflict in apps/server/src/ws.ts: upstream's new serverUpdateServer handler and the fork's serverGetProviderUsage handler were inserted at the same slot in the WS method map. Both handlers kept. Imports and yield* service bindings had already auto-merged; contracts (rpc.ts) carry both method definitions. No fork-identity files (nightly-fork.yml, app.config.ts) collided.

Verification

• Typecheck clean: @t3tools/contracts, t3 (server), @t3tools/web
• Provider-usage tests green: server 44, contracts 191, client-runtime 453

Note: pingdotgg#4286 adds a server self-update feature; it merged without touching the fork's nightly-fork.yml release pipeline.

Note

Add server self-update RPC, branch drift detection, and sidebar v2 refresh

• Introduces a server.updateServer WebSocket RPC with a ServerUpdateAction UI component that triggers server self-update, manages a 12-minute pending timeout, and offers a copy-to-clipboard fallback for manual updates via npx t3@<version>.
• Adds resolveServerSelfUpdateCapability to detect update paths (boot-service, respawn, desktop-managed) from environment capabilities; surfaces actionable guidance and the update action in the composer version-mismatch banner and connections settings.
• Adds resolveLocalCheckoutBranchMismatch to detect when a server thread's branch diverges from the local git checkout, and adds handlers in ChatView to reconcile the mismatch or switch checkout.
• Fixes resolveThreadPr to accept a structured { threadBranch, gitStatus, hasDedicatedWorktree } object, returning the PR for dedicated worktree threads regardless of stale/missing branch metadata.
• Replaces the horizontally-scrolling project chip UI in SidebarV2 with a dropdown menu, adds a rich per-row hover tooltip (SidebarV2ThreadTooltip) showing branch, environment, model, and mismatch warnings, and updates sidebar color tokens to zinc-based design tokens.
• Extracts t3 service CLI subcommands (install, update, uninstall, status) from connect.ts into a dedicated service.ts module and exposes them in the CLI.
• Adds ensurePinnedRuntimeInstalled to serialize concurrent pinned runtime installs with a sentinel-based validity check and a 10-minute npm timeout.
• Behavioral Change: networkStatus on mobile no longer classifies devices as offline when isInternetReachable is false but isConnected is true.
