fix(fleet): bounded-poll send --verify to eliminate false unverifiable on slow TUIs

Replace the single fixed 300ms capture-pane delay in `agent send --verify` with a
bounded polling loop. After sending, the loop polls `capture-pane` every 400ms
(VERIFY_POLL_INTERVAL_MS) up to a configurable total timeout (default 6000ms,
VERIFY_DEFAULT_TIMEOUT_MS). classifySendResult is called on each poll: accepted/draft
return immediately; unverifiable keeps polling until timeout, then fails closed with
the existing "no pane change after send" message.

New `--verify-timeout <ms>` option on `agent send` (default 6000ms documented).
Injectable SleepFn added to FleetCommandDeps for test isolation — no real sleeps in
tests. Exports VERIFY_POLL_INTERVAL_MS and VERIFY_DEFAULT_TIMEOUT_MS as constants.
classifySendResult and all other pure functions remain unchanged.

Tests: multi-poll acceptance on 2nd/3rd poll => exit 0; pane unchanged until timeout
=> exit 1; draft detected on first poll => exit 1. All 386 tests pass.

docs/fleet/PRD.md Known-limitations updated: verify now polls up to bounded timeout
(default ~6s, --verify-timeout); definitive acceptance still deferred to Phase-3
heartbeat-ack.

-# PRD — Mosaic Fleet Suite (init, configure, operate)
-
-> **Workstream:** W-FLEET (Fleet) under mission `mvp-20260312` · **Phase:** 3→4 productization
-> **North star:** [docs/fleet/north-star.md](./north-star.md) · prior: Phase-2 observability (#579), durable launch (#581), real-agent enablement (#583/#584/#586), releases 0.0.35–0.0.37
-> **Lead:** Jarvis @ `w-jarvis`. **Collaborator:** coder agent @ `dragon-lin` (jwoltje@10.1.10.37:coder0-0).
-> Owner of this file: Fleet workstream lead. Does not modify MVP single-writer control-plane files.
-
-## Mission
-
-Turn the proven fleet primitives into a **user-installable, AI-free-configurable fleet product**:
-a user runs `mosaic fleet init`, answers a few questions (general / coding / research / hybrid),
-gets a recommended set of agents plus one always-on orchestrator wired for chat-ops, and can
-operate, mutate, re-create, and observe the fleet — over tmux today and Matrix tomorrow — from
-CLI/TUI and (designed-for) the webUI.
-
-**Immediate tangible goal:** the **"Mos"** orchestrator agent running on `w-jarvis`, reachable
-in **Discord channel `1517622518662434996`** (server `1112631390438166618`). Once the fleet is
-functional, we use the fleet itself to continue the work.
-
-## Requirements
-
-### A. Configure-without-AI CLI
-| ID | Requirement |
-|---|---|
-| R1 | `mosaic fleet` command set is functional end-to-end (init/install/start/stop/status/ps/verify + agent verbs). |
-| R2 | `mosaic fleet init` is an interactive, **AI-free** CLI wizard. |
-| R3 | Init asks the **configuration type**: `general`, `coding`, `research`, `hybrid`, … (extensible). |
-| R4 | Based on the answer, the fleet is populated with a **recommended set of agents** (a preset). |
-| R5 | **Exactly one main orchestrator agent** is always configured, regardless of type. |
-| R10 | A set of **recommended configurations (presets)** ships for easy duplication. |
-| R8 | User can **re-create** the fleet when config needs change (idempotent re-init / reconfigure). |
-| R17 | Fleet controls are **simple and intuitive**. |
-
-### B. Comms & orchestrator chat-ops
-| ID | Requirement |
-|---|---|
-| R6 | Init can wire the orchestrator to a chat connector — **Telegram / Discord / Matrix / Slack** — for command + comms. |
-| R7 | Designed with the end-goal of **Matrix comms on a locally-controlled server**. |
-| R16 | Fleet supports **tmux AND Matrix** comms, **user-configurable** at init or any time. Not all users want Matrix. |
-| R19 | **"Mos" orchestrator on Discord** (`chan 1517622518662434996` / `srv 1112631390438166618`) on `w-jarvis` — the first live target. |
-
-### C. Runtime, health, lifecycle
-| ID | Requirement |
-|---|---|
-| R9 | Fleet is **mutable by the orchestrator agent** — add/remove agents per need. |
-| R13 | Fleet **gracefully handles Pi + Claude harness updates** — keep harnesses current. |
-| R14 | The **Pi harness is customized** for proper tool usage, etc. |
-| R15 | **Agent heartbeat** properly configured for **Claude AND GPT/Pi** agents. |
-
-### D. Surfaces, testing, docs
-| ID | Requirement |
-|---|---|
-| R18 | Fleet built so the **webUI can view / monitor / terminate / butt-in** on a session. |
-| R11 | Installed and **tested on both `w-jarvis` and `dragon-lin`**. |
-| R12 | **Documentation**: how to install, configure, and use the fleet. |
-
-## Architecture / approach
-
-- **Config model:** `roster.yaml` is the source of truth (already exists). Add **presets** (`general`/`coding`/`research`/`hybrid`) as shipped example rosters; `init` selects a preset, always injects the orchestrator, and writes the roster. Re-init = regenerate roster (preserve user/site overrides — mirrors install env-merge from #567).
-- **Orchestrator agent:** always present; carries the chat connector config (connector type + target IDs) so it can be commanded over chat. tmux is the substrate; the connector bridges chat ↔ the orchestrator session.
-- **Comms layers (R16):** (1) **tmux** inter-agent (`agent-send`, proven) — default, always available. (2) **chat connector** for human↔orchestrator (Discord now; Matrix the strategic target). (3) **Matrix** as the locally-controlled cross-agent bus (future). Connector is pluggable + reconfigurable.
-- **Heartbeat (R15):** runtime-agnostic launcher sidecar already covers pi/claude/codex (#584). Refine per-runtime (native HB) with the **custom Pi harness** (R14) + a Claude path.
-- **Updates (R13):** `mosaic update` (CLI) + a fleet-aware harness-update step that refreshes pi/claude/codex and re-launches agents safely (drain → update → relaunch via the durable launcher).
-- **webUI (R18):** the fleet exposes machine-readable state (`fleet ps --json` already carries tenant/host/heartbeat/managed) + control verbs (start/stop/watch/send); webUI consumes these (control plane rides federation per north star). Ensure a stable JSON contract + a terminate/attach(butt-in) path.
-
-## Phases (incremental, each shippable)
-
-| Phase | Deliverable | Notes |
-|---|---|---|
-| **F1 Presets + init wizard** | preset rosters (general/coding/research/hybrid) + always-orchestrator + AI-free `fleet init` selecting a preset; re-init idempotent | R1–R5, R8, R10, R17 |
-| **F2 Connector + Mos-on-Discord** | orchestrator chat-connector config (Discord first) + **Mos live on Discord `1517…`/`1112…`** on w-jarvis | R6, R19, partial R16 |
-| **F3 Heartbeat + harness** | HB confirmed for claude + pi/gpt; **custom Pi harness** (tool usage, native HB, model self-report); graceful harness updates | R13, R14, R15 |
-| **F4 Matrix + comms toggle** | Matrix connector (local server) + user toggle tmux/Matrix at init/anytime | R7, R16 |
-| **F5 Orchestrator-mutable fleet** | orchestrator can add/remove agents at runtime | R9 |
-| **F6 webUI hooks** | stable JSON contract + terminate/attach surface for webUI view/monitor/terminate/butt-in | R18 |
-| **F7 Test + docs** | install+test on w-jarvis AND dragon-lin; user docs (install/configure/use) | R11, R12 (runs alongside every phase) |
-
-## Work division (proposed — confirm with dragon-lin)
-
-- **Jarvis @ w-jarvis (Lead):** F1 presets+wizard, F2 connector+Mos-on-Discord, F5 mutability, F6 webUI hooks; merge authority + dual-engine reviews; co-testing on w-jarvis.
-- **coder @ dragon-lin:** F3 custom Pi harness + harness-update flow (pi/codex-savvy); plus its in-flight constitution P4–P6 (P4 installer rework underpins `fleet init`/updates — coordinate the install path). Co-testing on dragon-lin (R11).
-- **Shared:** F4 Matrix (whoever has bandwidth); F7 testing/docs continuous.
-
-## Immediate target: Mos on Discord (F2 first slice)
-
-The discord plugin is available (`~/.claude.json`). Path: configure the **orchestrator** as a durable
-fleet session running Claude Code with the discord plugin bridged to channel `1517622518662434996`
-(server `1112631390438166618`) on w-jarvis, with the existing Discord Bridge Protocol (ack within
-~3s, reply via `mcp__discord__reply`, no `AskUserQuestion`). Heartbeat via the launcher sidecar.
-
-## Success criteria
-
-- A non-AI user can `mosaic fleet init`, pick a type, and get a working fleet + orchestrator.
-- **Mos answers in Discord `1517…`** on w-jarvis.
-- Fleet runs + is observable (`fleet ps`) on **both** w-jarvis and dragon-lin.
-- Harness updates handled gracefully; HB healthy for claude + pi/gpt agents.
-- Docs let a new operator install/configure/use the fleet.
-- Re-init + orchestrator mutation work.
-
-## Assumptions (veto-able)
-
-- `ASSUMPTION:` presets ship as example rosters under the framework (`fleet/examples/*.yaml`), selected by `init`.
-- `ASSUMPTION:` chat connectors are pluggable; Discord first (target exists), Matrix is the strategic default later.
-- `ASSUMPTION:` "Mos" = a Claude Code orchestrator session with the discord plugin (reuses the documented Discord Bridge Protocol).
-- `ASSUMPTION:` per north star, runtimes default to Codex/pi-on-Codex for workers; the orchestrator "Mos" runs Claude Code (in Claude Code, which is allowed).

-    default is now Codex). The REAL durable-launch bug is **PATH**: the detached tmux
