Add Claude bridge Space focus seed

Context

Child of #10658. The Claude Desktop Shape C bridge path regressed after the wake/recovery work exposed a bad implicit invariant: Cmd+3 reliably selects the Claude Code tab, but it does not reliably focus the Claude Code prompt field.

Operator observations during the #10658 forensic thread:

• Cmd+3 is stable for selecting the Claude Code tab.
• Starting the bridge prep sequence with Cmd+A can select chat-history/session text when the prompt is not already focused.
• Typing a normal key inside the Code tab moves focus into the input field.
• Space is the safest focus seed observed so far: when the prompt is not focused, Space focuses the input without writing a visible character.
• Read-only System Events / Accessibility probes could detect AXFocusedWindow, but not prompt focus. AXFocusedUIElement returned missing value both before and after the operator manually focused the prompt.

Duplicate sweep notes:

• ask_knowledge_base(type: 'ticket', query='existing ticket Claude Desktop Space focus seed bridge daemon prompt focus Cmd+A transcript history') returned no relevant ticket.
• Local resource sweep across resources/content/issues, resources/content/issue-archive, and resources/content/discussions found adjacent tickets but no equivalent Space focus-seed ticket.
• Live latest-20 open GitHub issue sweep was read with title/author/labels. Adjacent entries included #10658 (broad Claude prompt-focus parent), #10647 (wake-stability epic), #10643 (Gemini parallel checkSunsetted originSessionId work), #10517 (HarnessPresence/wakePolicy), and #10422 (older AppleScript focus-steal bleed). None owns this minimal Claude Space focus seed.

The Problem

ai/scripts/bridge-daemon.mjs currently prepares the target prompt after tab selection by starting with destructive selection/cut chords:

activate Claude -> Cmd+3 -> Cmd+A -> Cmd+X -> paste wake -> Enter

When Claude Code tab owns focus but the prompt composer does not, Cmd+A can select transcript/history text instead of prompt text. This matches the hard-stop observation in #10658: the bridge selected active session text content rather than the input field.

The bridge therefore needs a non-destructive prompt-focus seed between Cmd+3 and Cmd+A for Claude Desktop.

The Architectural Reality

This is a Shape C bridge-daemon issue, not a fresh-session recovery issue and not a generic Claude API search.

Relevant current code:

• ai/scripts/bridge-daemon.mjs:575-583 resolves tabShortcut, with Claude defaulting to 3.
• ai/scripts/bridge-daemon.mjs:613-620 emits the tab-selection shortcut.
• ai/scripts/bridge-daemon.mjs:623-628 immediately runs Cmd+A / Cmd+X.
• ai/docs/wake-prompt-landing-matrix.md:5-7 states that adapter success is not enough; prompt landing is the observable success criterion.
• learn/agentos/tooling/WakeSubstrateIncidentProtocol.md:110-123 requires loop-level evidence before reactivation.

The known-good route before the regression was still osascript; the mistake was treating tab selection as prompt focus. tabShortcut: '3' remains correct as a tab selector. It is not a prompt-focus primitive.

The Fix

For Claude Desktop only, insert a Space focus seed after Cmd+3 and before any Cmd+A / Cmd+X sequence.

Target sequence:

activate Claude -> Cmd+3 -> Space -> Cmd+A -> Cmd+X -> paste wake -> Enter

Implementation expectations:

• Add the Space seed only for appName === 'Claude' or an explicit Claude-specific metadata primitive.
• Keep Antigravity's Cmd+Shift+I path untouched.
• Prefer key code 49 or an equivalent unambiguous AppleScript representation for Space.
• Add adapter-intent regression coverage in test/playwright/unit/ai/scripts/bridge-daemon.spec.mjs proving the Space seed is emitted after Claude Cmd+3 and before Cmd+A.
• Preserve the existing clipboard/user-draft restoration behavior.

Acceptance Criteria

• Claude bridge osascript sequence emits Cmd+3, then Space focus seed, then Cmd+A / Cmd+X.
• Antigravity bridge sequence remains unchanged and still emits Cmd+Shift+I for its focus path.
• A Playwright unit test covers the Claude osascript argument order: tab selection before Space, Space before Cmd+A.
• Live validation evidence is recorded against #10649 / #10658 for Claude Desktop with Code tab selected and transcript/history focused before wake.
• Live validation evidence confirms the payload lands in the Claude prompt field, not transcript/history text.
• Live validation explicitly notes the residual case where the prompt is already focused and contains a human draft; if Space mutates the draft, document the residual risk or add mitigation before wake reactivation.
• Wake safety gate remains tripped until #10649 matrix requirements are satisfied or @tobiu explicitly accepts a bounded override.

Out of Scope

• Implementing Claude Channels or CLI/session-target delivery.
• Implementing a deep native Accessibility inspector beyond the read-only probes already attempted.
• Fixing checkSunsetted originSessionId extraction; Gemini is already working #10643 in parallel.
• Changing fresh-session resumeHarness.mjs behavior.
• Reactivating bridge or heartbeat globally.

Avoided Traps

• Trap: Cmd+3 means prompt focus. Rejected. It means Code-tab selection only.
• Trap: start with Cmd+A and trust adapter success. Rejected. It can select transcript/history text.
• Trap: wait for Channels before restoring the known-good Shape C route. Rejected for this quick win. Channels remains strategic, but this ticket restores the osascript path that worked before.
• Trap: unit test equals reactivation proof. Rejected. Unit coverage proves adapter intent; #10649 live matrix proves loop safety.
