Summary

A running task showed a coral ring with a breathing dot beside its title, and a task waiting on a question showed a coral dot. The two differed only by shape, and the ring read like a radio button. Each status in the sidebar now has its own signal:

• Running: the row traces its outline. Two neutral comets circle the row's rounded outline every 2.4 s, and that's the only looping motion in the sidebar. Running rows show no glyph. The trace is ui::outline_trace: stroked paths on a canvas that fills the row, with no layout and no input.
• Needs you: a coral dot in a halo with a solid edge. This is the only coral status mark. The edge separates it from the green dot by shape, not colour alone, and keeps it readable on selected and hovered rows in light mode.
• Failed while unseen (red alert) and finished while unseen (green dot) look the same as before.
• Screen readers hear the status. A task row's description now leads with Running, Waiting for your answer, Last run failed, or Finished, not opened yet, followed by its project details. This works in English and Spanish. The description is cached per status and details, so the trace's repaints don't rebuild it.
• Paired computers' rows behave the same way.

Animation frame rate

At the 15 fps loop rate a moving arc steps visibly, so motion::Ticker now takes a per-loop rate through fps(), and the trace runs at 30 fps. Each view still gets a single coalesced repaint, at the rate of its fastest pending loop. Every request carries a generation, so the timer of a replaced request stays quiet and a view never runs two repaint chains, whatever order its loops ask in. Reduce Motion and background windows still stop loops on a resting frame, and thermal pressure still caps them at 6 fps.

Light mode

• Row buttons (pin, rename, menu): hover and press now use the shared overlay_hover and a new overlay_press instead of solid fills. Before this, on a selected row under the pointer the hover chip came out lighter than the row, a press flashed near white, and on a hovered row a press didn't show at all.
• Open task menu: while it's open, the row keeps its hover fill and the action strip keeps covering the title, the way project headers already do.
• New tokens: activity_trace (light #6e6f7e) and attention (light #e8633d, maple-700). The running grey had been 1.7:1 on a selected row and the coral 2:1 on the sidebar. The contrast test now holds both to 3:1 on every resting surface.
• The shared selected fill, which also colours pressed controls and off toggles elsewhere, doesn't change.

Screenshots

Sidebar rows rendered with gpui's offscreen Metal renderer from the real row code. Before is master; after is this branch. The rows are, top to bottom: running, needs you, running and selected, failed, finished, and no status.

From left to right: a waiting task while it's selected, the same task while another task is selected, and its row under the pointer with the action strip covering the mark.

From left to right: the "…" button under the pointer, the task menu just opened, and the pointer moved into the menu. The row keeps its fill, and the open button stays pressed.

Validation

• cargo test -p maple-agent-app --bin maple-agent: 1,346 passed, 0 failed, 3 ignored at ea85e9fa. This includes the new geometry tests for the trace outline, the scheduler tests (a replaced timer never claims a newer request at its rate), the contrast test with the two new tokens, and the i18n catalog and translation-review tests.
• Clippy with -D warnings passes on maple-agent-app, for all targets with default features and for --no-default-features --features acp,proxy. It allows unexpected_cfgs from the objc macros and clippy::nonminimal_bool in code this PR doesn't touch. cargo fmt --all -- --check passes.
• The Spanish revision record was rewritten by record_reviewed_translations, which is what just translations-reviewed es runs.
• Live debug app in light mode, with real tasks:
  • The trace runs on a running row, selected or not.
  • A task that asks a question shows the edged halo and drops the trace. The halo stays visible while another task is selected.
  • Answering clears the halo.
  • macOS's accessibility tree reads help="Waiting for your answer. Untitled project" while the task waits, and help="Untitled project" after.
• This Mac has no Nix, so just ci didn't run on the pinned toolchain. Everything ran on rustc 1.96 through the shared Agent cache.

Notes

• UI only. No stored values, protocol strings or element ids change.
• New strings: chat-task-running, chat-task-needs-you, chat-task-failed, chat-task-finished-unseen, and chat-task-status-details, in English and Spanish.
• Not in this PR: a status summary on collapsed folders, and keyboard focus revealing row actions.

Merge order

Trial merges against the open PRs at their current heads are clean except #1515, the motion PR. Both PRs rewrite the motion.rs module docs, both append a test module at the end of motion.rs, and both change the task rows in sidebar.rs and sidebar_computers.rs. Whichever merges second needs a rebase.
