feat: commit message.

[knightedcodemonkey]

• closes Allow custom commit message in Open PR / Push Commit drawer flows #43

[Copilot]

Pull request overview

Adds a user-configurable commit message to the GitHub PR drawer so Open PR and Push Commit flows can use a non-hardcoded commit message (Issue #43), along with UI styling, e2e coverage, and CI workflow updates.

Changes:

• Adds a “Commit message” input to the PR drawer UI and wires its value into GitHub upsert commit calls for both Open PR and Push Commit flows.
• Updates PR drawer mode behavior (Open vs Push) by disabling/hiding certain fields and adjusting default branch naming.
• Expands Playwright coverage for commit message behavior and active PR context recovery; updates Playwright workflow triggers/concurrency.

• -webkit-appearance: none; was removed from this select style while other select rules still include it (e.g. src/styles/panels-editor.css). This can lead to inconsistent native select UI in Safari/WebKit; consider standardizing the appearance reset across all select styles.

.ai-chat-model-picker select {
  appearance: none;
  width: 100%;
  min-width: 0;
  box-sizing: border-box;
  border: 1px solid var(--border-control);
  border-radius: 9px;
  background: var(--surface-select);

The new tests cover passing a custom commit message for both Open PR and Push Commit flows, but they don't verify the repository-scoped persistence requirement (commit message restored after closing/reopening the drawer and after a reload). Add a Playwright assertion that sets a commit message, reloads (or reopens the drawer), and confirms the value is prefilled as expected.
