feat(web): settle and restore threads with a keyboard shortcut - #8089

💭 This diff is really about keybindings, not Effect services—the changed files just add a command literal and default binding, with the ChatView.tsx change using a React hook and Atom-style result handling unrelated to Effect service creation. I'll do a quick sanity check that useThreadActions exists and glance at the ChatView diff context to confirm nothing else needs attention.

1. browse_code — In apps/web/src/hooks/useThreadActions.ts (or .tsx), what does the hook return — does it expose a settleThread function, and what is its return type (does it return a promise of an Atom command Exit/Result with a _tag)? Also confirm helpers isAtomCommandInterrupted and squashAtomCommandFailure exist and their signatures.

2. git_tools — supportsSettlement|handleUnsettleActiveThread|activeThreadSettled

💭 This PR doesn't create, move, or refactor Effect services in a way that violates conventions, so there are no findings. Since the response must fit the JSON schema despite the instruction to say "All clear" verbatim, I'll set the status to success with title and summary both reading "All clear."
