chore(desktop): upgrade Electron to 44.4.3 - #50327

Electron 42.10.1 → 44.4.3 (Chromium 148 → 152, Node 24.19 → 24.21). 42 leaves the supported window when 45 ships.

Breaking changes that applied

// before
const image = clipboard.readImage()
clipboard.writeText(text)

// after
const items = yield* Effect.promise(() => clipboard.read())
const found = ["image/png", "image/jpeg"]
  .flatMap((mime) => items.filter((item) => item.types.includes(mime)).map((item) => ({ item, mime })))
  .at(0)
const payload = yield* Effect.promise(async () => found.item.getType(found.mime)) // Blob
const image = nativeImage.createFromBuffer(Buffer.from(yield* Effect.promise(() => payload.arrayBuffer())))
yield* Effect.promise(() => clipboard.writeText(text))

Benchmarks

bench:devex — cold bun dev:desktop to Home, fresh profile (Windows x64). Running it surfaced a dormant fresh-database bootstrap race in core, split out as #50344; the 42 baseline completed 3 runs before that race killed run 4, and the 44 column was measured with #50344 applied (5/5). The dominant phase is the source CLI booting under Bun and drifts between sessions; electronStartup is the Electron-attributable phase.

The bench itself was stale (loading task finished, awaiting server ready, server ready no longer log); milestones now track layers ready and the current window-before-service order.

bench:startup — packaged builds, same bundled CLI, alternating launches, warm service, 5 runs.

Notes

• [email protected] still uses positional console-message args in spyRendererConsole (upstream); args are deprecated, not removed.
• test/browser-native.test.ts fails on v2 independently: browser.preview (feat(app): open agent-referenced files as rich artifact tabs #49882) is not exercised by the operation-coverage assertion.
• Electron 45 heads-up: sandboxed preload loses Buffer/setImmediate/require("events"); sync safeStorage deprecated; display-capture permission split from media.
