fix(desktop): mac start:desktop crash from rewritten framework symlinks

[TheIcarusWings]

pnpm start:desktop crashed at launch on macOS with repeated "icudtl.dat not found in bundle" and a fatal unusable GPU process.

Root cause: buildMacLauncher copies Electron.app into .electron-runtime/ with cpSync, which by default rewrites the framework's relative symlinks (such as Resources -> Versions/Current/Resources) into absolute paths pointing back into node_modules. Electron's sandboxed helper processes cannot follow symlinks that escape the app bundle, so ICU data lookup fails and every helper crashes. Dev mode is unaffected because it execs the original bundle; only the production start path runs the copy.

Fix: pass verbatimSymlinks: true so the staged bundle stays self-contained, and bump LAUNCHER_VERSION so previously staged bundles with rewritten symlinks are invalidated and re-copied instead of being reused by the metadata check.

Verified by reproducing the crash with a minimal Electron app against the broken copied bundle, then confirming pnpm build && pnpm start:desktop launches cleanly after the fix (window up, GPU and network helpers alive, no ICU errors). Also verified the version bump re-stages an existing stale bundle without manual deletion.

Approvability

Verdict: Approved

This is a targeted bug fix that adds verbatimSymlinks: true to preserve Electron framework symlinks during Mac app bundle copying, preventing a crash in sandboxed helper processes. The change is self-contained with clear intent and minimal risk.
