* feat: show activity indicators for terminals and their workspaces

A terminal surfaces whether the agent running inside it is working, idle,
or waiting for input as a tab dot, and that state rolls up into the
owning workspace status — so an agent run inside a terminal reads the
same as a native agent. Finishing a turn raises a "Terminal finished"
notification that routes back to the workspace terminal tab.

Activity is reported by the agents, not parsed from terminal output:
Claude and Codex command hooks and an OpenCode plugin post coarse state
to a local daemon endpoint, and a source-agnostic per-terminal tracker
maps it to working/idle/attention. Hook installation is opt-in and off
by default because it edits your real agent config files; enable it under
a host's Terminal settings and Paseo installs the hooks globally, runs
them via `paseo hooks <agent> <event>`, and removes its own hooks when
you opt back out. Installation and reporting are idempotent and
fail-open, so a missing or failing hook never breaks the user's shell.

* Fix terminal activity routing and CI test

Test drift: anchor the provider-leak test to the repo root instead of process.cwd() so it passes under the server workspace CI runner.

Also restore auth-first JSON parsing outside the terminal-activity route and route subdirectory terminal activity to the deepest active workspace.

* Fix workspace resolver regression

Code drift: terminal activity routing needs parent-workspace prefix matching, but agent directory and historical fetches keep exact registered workspace semantics, including archived exact matches.

* Narrow terminal/draft workspace subscriptions to the fields they use

terminal-panel and the draft agent tab subscribed to the whole workspace
descriptor via useWorkspace but read only workspaceDirectory (plus projectKind
in TerminalPanel, plus id in the draft tab), so they re-rendered on any field
change of that workspace (status, diffStat, scripts). Switch them to the
existing useWorkspaceDirectory / useWorkspaceFields hooks so they re-render only
when the fields they actually read change. No behavior change.

* Make TerminalActivity.state forward-compatible

A strict z.enum rejects the whole payload when a newer daemon reports a
terminal activity state this client predates, breaking the protocol's
old-client-parses-new-daemon contract (the activity field has no .catch at
its embedding in messages.ts, so the failure bubbles up). Degrade unknown
states to "idle" (no indicator, no notification) via .catch, matching the
enum-with-catch pattern used elsewhere in the protocol. Add a forward-compat
regression test.

f352072dac Fix coding-agent terminal shortcuts not working on Windows (#1509)
* Fix coding-agent terminal shortcuts not working on Windows

On Windows, opening a Terminal profile (Claude Code / Codex / OpenCode) did
nothing, and afterwards even a plain New Terminal stopped working until restart.

Three Windows-specific problems combined:

- A failed node-pty conpty spawn completes asynchronously on its conout worker
  thread; the uncaught exception escaped the per-request try/catch and crashed
  the whole terminal worker, severing every terminal. Add uncaughtException /
  unhandledRejection guards so a single bad spawn keeps the worker alive.
- Profile commands were passed to conpty unresolved. conpty's CreateProcess
  ignores PATHEXT, so bare codex (npm codex.cmd) wasn't found and .cmd/.bat
  shims can't run directly. Add resolveTerminalSpawnCommand() to resolve the
  real path and route .cmd/.bat through cmd.exe /c on Windows.
- winget-installed CLIs (e.g. Claude Code) live under the winget Packages dir
  and aren't on PATH. findExecutable() now falls back to those known install
  locations, so all providers and terminal profiles benefit.

Also surface a failed terminal create to the user via a toast instead of
silently dropping the error.

* Address review: simplify winget scan, narrow worker exception guard

- Drop the single-element WINGET_PACKAGE_BIN_SUBDIRS loop in executable.ts and
  map package dirs directly to the root <name>.exe candidate.
- Remove the unhandledRejection handler in the terminal worker (only the
  uncaughtException path is exercised by conpty's async spawn failure) and
  expand the comment to explain the keep-alive trade-off and the absence of a
  worker restart path.

* Refactor executable resolution out of utils

* Serialize terminal create requests in worker

Mohamed BoudraandGitHub 72b67f48e3 Eliminate spiky terminal lag under load (#1500)
* Eliminate spiky terminal lag under load

Terminal output stuttered during heavy output and when the daemon was
busy. Two compounding causes, both confirmed by measurement:

- Every 256KB of output, the daemon dropped pending frames and re-sent a
  full cell-grid snapshot (cloned across IPC, stringified to JSON) — a
  10MB build did this ~40 times. The snapshot fallback is now gated on
  real client backpressure (ws bufferedAmount), so a client that keeps
  draining streams continuously and never pays the snapshot tax. This
  also removes the periodic GC hitch the churn caused.
- Per-chunk overhead on the shared event loop: one IPC message per pty
  chunk, a duplicate input-mode regex scan on the daemon main loop, a
  double JSON.stringify per outbound message, and 16KB string realloc
  per chunk. Output now coalesces in the worker before IPC (leading-edge
  so keystrokes still echo immediately), the duplicate scan is gone, and
  the client feeds xterm back-to-back instead of one render tick a frame.

Adds eventLoopDelay percentiles to ws_runtime_metrics for main-loop
stall visibility, plus a reproducible Node benchmark (no port 6767).

Measured: echo p50 7.7ms to 2.3ms; a 2MB burst now streams fully with
zero snapshots; loop-stall spikes 100-173ms to 2ms.

* Guard trace-level check against partial logger stubs

The isLevelEnabled gate added for the emit() perf fix crashed every
session test that injects a hand-rolled logger stub (10 of them omit
isLevelEnabled). Real pino loggers always provide it; optional-chaining
keeps the perf gate intact in production and no-ops on stubs.

* Make recent-output exit-summary test deterministic

The added test self-exited the child immediately after writing 3000
lines, then asserted the newest line was in the exit summary — but the
summary reads the headless xterm buffer, which parses writes
asynchronously, so a loaded CI runner saw a stale buffer (line-2707 not
line-2999). Keep the process alive and poll the parsed buffer until the
final line lands before killing, removing the race.

* Skip ConPTY-fragile worker terminal tests on Windows

The coalescing and input-mode-preamble tests assert byte-contiguous PTY
output and an exact kitty-escape round-trip. Windows ConPTY injects
repaint sequences between writes and normalizes the escape, so both time
out there while passing on Linux/macOS. Gate them with skipIf(win32),
matching the existing terminal-test convention for PTY-sensitive cases.

* Apply terminal barriers immediately when no writes are pending

A barrier op (snapshot/restore/clear) only needs the sentinel-write gate
to wait out plain writes still parsing in xterm's buffer. When none are
ungated — at mount, or right after another barrier — the sentinel cost a
wasted parse cycle, adding latency to the first snapshot/restore on the
hot first-paint path. Track ungated writes with a flag and skip the
sentinel when there's nothing to gate.

* Fix mobile startup saved-host e2e

* Unskip Windows worker terminal coverage

* Tighten worker coalescing assertion

* Reset terminal ungated writes on unmount

* Fix terminal regressions found in adversarial review

Three issues this PR's terminal changes introduced:

- Worker snapshot could duplicate coalesced output. getTerminalState
  snapshotted without flushing the worker output coalescer, so a batch
  spanning the snapshot point carried a revision past it and the
  controller's dedup couldn't drop it — the client saw the bytes twice.
  Flush before snapshotting.
- Relay clients lost backpressure protection. The snapshot fallback was
  gated on bufferedAmount, which the multiplexed relay socket reports as
  absent; that read as 0 ("keeping up") so a slow relay client never
  caught up via a snapshot. Distinguish "no signal" (null) from 0 and
  keep the unconditional byte-threshold fallback for signal-less
  transports, preserving the pre-change relay behavior.
- Recent-output buffer was no longer a hard cap. A single chunk larger
  than the limit was retained whole; slice its tail.

Documents the live-restore preamble gap (unreachable: no client sends
restore mode "live").

* Skip input-mode preamble test on Windows ConPTY

CI confirmed Windows ConPTY normalizes away the kitty keyboard escape
the child writes, so it never reaches the worker's input-mode tracker
and the preamble stays empty — the test times out. ConPTY can't exercise
this contract; the coalescing test (file-gated, line-oriented) stays on
all platforms, only the preamble assertion is gated to Linux/macOS.
