fix: resolve Windows startup crash from Node entry path (#105)

[Talljack]

Summary

Fixes #105.

Use relative server.js when launching the bundled Node sidecar to avoid Windows verbatim-path resolution failures. Executable, working directory and environment remain unchanged.

Add automated startup checks on pull requests and main pushes for Windows, macOS, Linux, production Web and native iOS simulator.

Issues found and fixed by verification

• iOS eagerly preloaded four hidden WebViews while the visible tab initialized the same IndexedDB; fresh simulator comparison reproduced a blank dashboard. Load tabs on first selection instead, preserving loaded tab state.
• Releasing an unvisited iOS tab constructed its lazy WebView during deinitialization and crashed. Pair observer cleanup with an explicit registration flag.
• Regression tests observed both original iOS failures before the fixes. No relaxed rendering assertions or timeout increases.

Final validation: 560168c

All startup checks passed on the current head:

• Windows: bundled Node regression tests, NSIS build/install into a Unicode/space path, installed process and local server alive for 60 seconds, dashboard/library rendered in Chromium.
• macOS: bundled app launched from a Unicode/space path; same process/server/browser checks.
• Linux: deb installed, executable launched under Xvfb; same checks.
• Web: production server and actual dashboard/library headings, no uncaught page errors, 60-second health observation.
• iOS simulator: native unit and UI checks including three cold launches, real WKWebView dashboard content, 65-second survival, first Library load and return to Today.
• Standard lint, typecheck and build checks passed.

iOS: https://github.com/Talljack/echo-type/actions/runs/34490025466

Artifacts include screenshots, Windows/Linux test installers and iOS XCTest results/logs. Local smoke-harness tests also pass.

Scope and limits

Desktop page checks use separate Chromium against the bundled sidecar, not full embedded-window interaction. iOS uses an actual simulator WKWebView. These checks do not certify every OS/version/architecture, physical hardware, production signing, SmartScreen/Gatekeeper or external AI services. See docs/design/startup-verification.md.

No data migration, version bump, release publishing or merge performed.
