Restore project thread trees and align desktop update versions

[Saint-14-research]

Summary

• make expandable per-project thread trees the default sidebar while retaining the flat view as an opt-out
• prefer a matching packaged desktop CLI for SSH-hosted sessions to prevent client/server schema skew
• give local desktop artifacts the canonical update feed and keep packaged version producers aligned at 0.0.33

Verification

• 86 focused tests passed across settings, SSH runner, desktop artifact, and release-version synchronization
• contracts, SSH, desktop, and web typechecks passed
• packaged macOS artifact reports 0.0.33 in Info.plist, rendered Settings, and bundled t3 --version
• identical app.asar verified on MacBook Air and Mac mini

Note

Medium Risk
Changes a user-facing default for all clients and alters SSH remote CLI resolution, which can affect remote session startup and version compatibility. Packaging/update-feed tweaks are lower risk but touch release paths.

Overview
Makes expandable per-project thread trees the default sidebar again (legacySidebarEnabled defaults to true), with the flat list kept as an explicit opt-out. Settings copy and tests are updated to match.

For packaged macOS apps, SSH remote sessions now prefer a version-matched installed desktop CLI (via ELECTRON_RUN_AS_NODE) before falling back to npx/npm, reducing client/server schema skew.

Also bumps packages to 0.0.33, defaults local desktop builds to the canonical GitHub update feed, and reuses the prebuilt production icon.icns when staging Mac icons.

Note

Restore project thread trees as default sidebar and add desktop CLI path for remote SSH runner

• Changes legacySidebarEnabled default from false to true in ClientSettingsSchema, making the expandable per-project thread tree the default sidebar for all clients without an explicit setting.
• Extends the SSH remote runner script to prefer an installed desktop CLI (matched by version) before falling back to a global t3 install or package-based execution, using ELECTRON_RUN_AS_NODE to invoke the Electron binary as a Node process.
• On macOS packaged builds, resolveDesktopSshCliRunner now includes a desktopCli descriptor in the runner options, pointing at the installed app's Electron executable and server entry.
• Production mac desktop builds now use a pre-built icon.icns from apps/desktop/resources/icon.icns instead of generating one from a PNG; local builds without repo env vars default to the pingdotgg/t3code GitHub repository for update config.
• Behavioral Change: the sidebar now defaults to the project tree view; users who preferred the flat list must explicitly opt out.

Sidebar flashes wrong default

Medium Severity

Flipping legacySidebarEnabled to default true leaves useLegacySidebarEnabled gating with settingsHydrated && legacySidebarEnabled, which still forces false until hydration. Most users briefly mount the flat sidebar, then remount the project-tree sidebar once settings load.

Approvability

Verdict: Needs human review

This PR changes the default sidebar UI for all users and adds new desktop CLI detection logic. An unresolved review comment identifies a potential sidebar flash bug during hydration that should be addressed before merging.
