Summary

Adds a per-child idle-state classifier (5 states × 3 strategies + regex promoters) wired through MCP ProcessInfo / get_process_status and rendered as a state glyph in the sidebar.
Adds the full Solo timer tool set: timer_set, timer_fire_when_idle_any / _all, timer_cancel, timer_pause, timer_resume, timer_list. timer_wait is now a thin wrapper over the shared manager. Top-level callers can attach timers via owner_process_id; orchestrator-level callers (empty owner) have universal management rights.
Exposes Emulator.Title() on the libghostty-vt wrapper so OSC 0/1/2 updates feed the title-stability and title-status strategies without a cgo callback.
Sidebar shows a nearest-pending-timer indicator (⏱ 12s / ⏸ paused) on rows that own a timer.
New idle_detection preset block with bundled defaults for the first-party claude / codex / opencode presets.
New harness wait_until_mcp step type that polls an MCP call until an assertion holds.

Out of scope (follow-ups)

LLM-driven auto-summarization (Solo's other half).
Interactive sidebar timer affordances (view / fire-now / pause inline).

Test plan

go build ./...
go test ./... — all green
Harness scenarios (run individually): idle_output_activity, idle_osc_title_stability, idle_osc_title_status, idle_regex_promote, timer_set_delivers, timer_cancel, timer_pause_resume, timer_idle_any_fires_on_transition, timer_idle_all_pending, timer_idle_all_already_satisfied
Manual smoke: spawn the bundled claude preset, watch the sidebar glyph cycle while the agent works / waits for input.

## Summary - Adds a per-child idle-state classifier (5 states × 3 strategies + regex promoters) wired through MCP `ProcessInfo` / `get_process_status` and rendered as a state glyph in the sidebar. - Adds the full Solo timer tool set: `timer_set`, `timer_fire_when_idle_any` / `_all`, `timer_cancel`, `timer_pause`, `timer_resume`, `timer_list`. `timer_wait` is now a thin wrapper over the shared manager. Top-level callers can attach timers via `owner_process_id`; orchestrator-level callers (empty owner) have universal management rights. - Exposes `Emulator.Title()` on the libghostty-vt wrapper so OSC 0/1/2 updates feed the title-stability and title-status strategies without a cgo callback. - Sidebar shows a nearest-pending-timer indicator (`⏱ 12s` / `⏸ paused`) on rows that own a timer. - New `idle_detection` preset block with bundled defaults for the first-party claude / codex / opencode presets. - New harness `wait_until_mcp` step type that polls an MCP call until an assertion holds. ## Out of scope (follow-ups) - LLM-driven auto-summarization (Solo's other half). - Interactive sidebar timer affordances (view / fire-now / pause inline). ## Test plan - [x] `go build ./...` - [x] `go test ./...` — all green - [x] Harness scenarios (run individually): `idle_output_activity`, `idle_osc_title_stability`, `idle_osc_title_status`, `idle_regex_promote`, `timer_set_delivers`, `timer_cancel`, `timer_pause_resume`, `timer_idle_any_fires_on_transition`, `timer_idle_all_pending`, `timer_idle_all_already_satisfied` - [ ] Manual smoke: spawn the bundled claude preset, watch the sidebar glyph cycle while the agent works / waits for input.

Add idle-state classifier and Solo-parity timer tools 2b9e1ed77c

Classifies every running child as idle/working/thinking/permission/error
using one of three pluggable strategies (output_activity,
osc_title_stability, osc_title_status) plus optional regex promoters
applied to the tail of recent output. State and last-match reason are
exposed via MCP on ProcessInfo and get_process_status. Per-preset
configuration lives on a new preset.IdleDetection block with bundled
defaults for the first-party claude/codex/opencode presets.

OSC title plumbing is exposed as Emulator.Title(), polled from the
session pump after each emulator write so title-change activity feeds
into the classifier without an extra cgo callback.

The MCP timer surface expands to match Solo: timer_set,
timer_fire_when_idle_any/all, timer_cancel, timer_pause, timer_resume,
timer_list. timer_wait is now a thin wrapper that shares the same
manager so it shows up in timer_list while pending. Timer bodies are
delivered to the owner process through the existing
InjectAsOrchestrator path. Top-level (non-agent) callers can attach
timers to a specific process via owner_process_id; omitting it grants
universal cancel/pause/resume/list privileges.

The sidebar gains a state glyph per process row and appends a
nearest-timer indicator when one is pending or paused.

Tests: idle_test.go covers the classify() pure function across the
three strategies and regex promotion; timers_test.go covers the
manager. Harness scenarios cover output_activity, osc_title_stability,
osc_title_status, and regex promotion, plus timer_set delivery,
cancel, pause/resume, idle_any-on-transition, idle_all-pending, and
idle_all-already-satisfied. A new wait_until_mcp harness step type
polls an MCP method until an assertion holds.
