Feat: update complete onboarding helper (#299)

* fix(e2e): make completeOnboardingIfVisible resilient by delegating to walkOnboarding

The previous implementation did a single onboardingOverlayLikelyVisible()
check before calling walkOnboarding. This created a timing race: if onboarding
had not yet rendered at call time the helper returned early, leaving the
overlay blocking subsequent steps.

walkOnboarding already handles both cases correctly — it polls up to
8 × 400 ms for the overlay before giving up, then no-ops gracefully if not
visible. completeOnboardingIfVisible now delegates to it unconditionally,
eliminating the race without changing observable behaviour.

Also updates the section comment to accurately describe the current 5-step
onboarding sequence (Welcome → Local AI → Screen & Accessibility → Tools →
Skills) following the removal of MnemonicStep in #279.

Closes part of #201

* fix(e2e): use completeOnboardingIfVisible in conversations spec

conversations-web-channel-flow.spec.ts was the only spec that called
walkOnboarding directly instead of the shared completeOnboardingIfVisible
helper. Align it with all other specs so the single resilient code path
is used consistently.

Closes #201

* fix(e2e): add clang and cmake to Dockerfile dependencies

Updated the e2e Dockerfile to include clang and cmake as additional dependencies, enhancing the build environment for end-to-end testing.
