Small gaps batch: live thought line, compact-on-send, secret card, /goal, subagent stop, worktree location, onSettle

Small items (S unless noted), each independently shippable:

Live thought line. The working row shows the agent's latest thinking or summary line, not just "Thinking…" (src/workingLabel.ts:33). (Live thought line on the working row (#1531) #1535)
Compact on send for cold threads. When a Claude thread has been idle for more than about 1 h (cache expired) and its context is large, show a "Compact first (≈N tokens)" chip on the composer. (Compact-first chip on cold, large Claude threads (#1531) #1543)
Secret request card. An ask_user-style MCP tool that asks for a secret. The value goes into the run env or a temp file, never into the transcript or store. Today only Codex/elicitation fields are masked (InputPrompt.tsx:62). Overlaps Secret placeholders: orchestrator substitutes real values, agents never see them #289. (secret_request: masked secret card, value only in the run env (#1531) #1542)
/goal end to end. Today it only prefills the draft (slashCommands.ts:101). Wire it to the provider's native goal where one exists, and show goal status in the header. (/goal end to end: stored goal, native Codex goal, header chip (#1531) #1539)
Stop button on subagent/team rows in the Agents panel (the thread_stop MCP tool exists). Make thread ids clickable as links in replies. (Stop button on worker rows; clickable thread ids in replies (#1531) #1536)
Choose where worktrees are created (fixed at userData/worktrees, electron/main.js:906). Include the WSL/remote roots in GC (P2: Include WSL worktree roots in orphan sweep and retention GC #1401). (Choose the worktree location; solenta.json onSettle (#1531) #1544)
onSettle action in solenta.json: run a project action when a worktree thread settles (teardown, stop dev DB). (Choose the worktree location; solenta.json onSettle (#1531) #1544)
Merge niceties: strip agent Co-authored-by trailers from the squash message (opt-in); "Open revert PR" on a merged PR. (Merge niceties: strip agent co-authors, Open revert PR (#1531) #1537)
Window capture text. The AppSnap capture also attaches the window's accessibility text, not just the PNG (electron/appsnap.js). (M) (AppSnap: attach the window's accessibility text beside the PNG (#1531) #1540)
Misc: reopen the last closed pane; a provider filter on Usage; custom model prices. (Reopen closed pane, Usage provider filter, custom model prices (#1531) #1538)

PRs opened, one per item:

Live thought line on the working row (#1531) #1535 Live thought line
Stop button on worker rows; clickable thread ids in replies (#1531) #1536 Stop button on subagent rows + clickable thread ids
Merge niceties: strip agent co-authors, Open revert PR (#1531) #1537 Merge niceties (strip agent co-authors, Open revert PR)
Reopen closed pane, Usage provider filter, custom model prices (#1531) #1538 Misc: reopen closed pane, Usage provider filter, custom model prices
/goal end to end: stored goal, native Codex goal, header chip (#1531) #1539 /goal end to end (native Codex thread/goal/*, prompt note elsewhere, header chip)
AppSnap: attach the window's accessibility text beside the PNG (#1531) #1540 Window capture text (draft: not yet tried on a real window)

Still in progress: compact-on-send chip, secret request card, worktree location + onSettle.

The rest of the items are up:

secret_request: masked secret card, value only in the run env (#1531) #1542 Secret request card (secret_request tool; value kept in memory and the run env only)
Compact-first chip on cold, large Claude threads (#1531) #1543 Compact-first chip on cold, large Claude threads
Choose the worktree location; solenta.json onSettle (#1531) #1544 Choose the worktree location (GC now covers custom and WSL roots) + solenta.json onSettle

Every item in this issue now has a PR: #1535–#1540 and #1542–#1544. #1540 is a draft because it hasn't been tried on a real window. #1537, #1538 and #1544 all add a setting on the same lines of electron/test/budget-spend.test.js, so they need small sequential rebases.
