fix: restore live Electron daemon bridge boot

[parsakhaz]

Summary

• restore Electron preload startup after the daemon bridge split by keeping the renderer-side channel classifier runtime-safe under sandboxed preload constraints
• register window:is-focused before the renderer loads so focus-state IPC no longer races app startup
• keep the shared daemon channel ownership map authoritative for main/runtime code and add a regression check that preload's inline classifier stays aligned

Testing

• pnpm typecheck
• pnpm lint
• CI=1 pnpm --filter main test -- --run
• pnpm run build:main
• PANE_DIR=/tmp/pane-phase2-final-ci xvfb-run -a pnpm test:ci
• PANE_USE_PTY_HOST=1 PANE_DIR=/tmp/pane-phase2-live-smoke-ptyhost xvfb-run -a pnpm test:ci
• PANE_DIR=/tmp/pane-phase2-review-smoke xvfb-run -a pnpm test:ci
• live Electron smoke via direct launch and Playwright-attached renderer probes covering preload boot, getPlatform, getVersionInfo, project create/list, folder create/list, session create/list, and resource monitor snapshot
