fix(linux): reafirmar alwaysOnTop no blur (overlay caía pro fundo ao clicar fora)

[gabrielscordeiro]

Problema

No Mutter/XWayland, o estado _NET_WM_STATE_ABOVE do overlay oscila ao perder o foco: ao clicar em qualquer outra janela ou no desktop, o overlay caía para trás de tudo e só voltava via toggle (tray/atalho) ou revealIfHidden.

A causa raiz é que o always-on-top só era afirmado uma vez na criação da janela (main.js setAlwaysOnTop(true, 'screen-saver')). Os únicos pontos que reafirmavam o estado (toggleWin/revealIfHidden) só disparam em ações do próprio app — nunca no blur involuntário (clicar fora). O CHANGELOG da v0.6.7 já reconhece que o alwaysOnTop oscila em X11 e adicionou moveTop() no toggle/reveal, mas o caminho do blur ficou sem cobertura.

Correção

Adiciona um listener de blur que reafirma o estado, seguindo o mesmo padrão já usado no toggle/reveal:

win.on('blur', () => {
  try { win.setAlwaysOnTop(true, 'screen-saver'); } catch {}
  try { win.moveTop(); } catch {}
});

Mudança mínima (+8 linhas, sem remoção nem refactor).

Verificação

Testado com npm start (XWayland) no cenário do bug:

Passo	Antes	Depois
Estado inicial	_NET_WM_STATE_ABOVE presente	idem
Ativar outra janela (dispara blur)	overlay cai pro fundo	—
Estado do overlay após o blur	perde _NET_WM_STATE_ABOVE	mantém _NET_WM_STATE_ABOVE, permanece no topo ✅

Fluxos de toggle/tray/reveal seguem inalterados (já chamavam os mesmos dois métodos).

Summary by CodeRabbit

• Correções
  • Corrigido o comportamento de janelas configuradas para permanecerem sempre no topo em ambientes Linux com Mutter/XWayland.
  • A janela agora recupera automaticamente sua posição de destaque ao perder o foco, evitando oscilações ao alternar entre janelas ou áreas de trabalho.

Warning

Review limit reached

@gabrielscordeiro, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 52 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Sou coelho, salto no topo ligeiro,
A janela não perde seu paradeiro.
Se o foco escapar pelo ar,
blur a fará retornar.
Sempre no alto, sem tropeçar!
