feat(terminals): reprise de conversation par cellule + fix ordre d'écriture

Browse Source 
Permet de recharger la conversation CLI précédente de chaque cellule à la
réouverture du projet, de façon universelle (indépendant du modèle/CLI).

- profil AgentRuntime: bloc déclaratif optionnel `session { assignFlag, resumeFlag }`
- LeafCell: `conversationId` (persistant, distinct du SessionId PTY) + `agentWasRunning`
- runtime: SessionPlan (None/Assign/Resume) + composition pure des args
- LaunchAgent: décide Assign vs Resume, génère l'UUID, remonte l'id assigné
  (persistance par l'appelant via setCellConversation — découplage SRP)
- close: SnapshotRunningAgents fige `agentWasRunning` avant le kill-all
  (statut clot/en cours universel, sans parsing CLI)
- SessionInspector: port optionnel best-effort + adapter ClaudeTranscriptInspector
- popup de reprise par cellule (statut + sujet/tokens si dispo), intercalée
  avant le Resume auto, jamais sur le chemin reattach

fix(terminals): sérialise les écritures PTY (file FIFO par handle) — corrige
les caractères mélangés/accents dus au réordonnancement des invoke Tauri concurrents

fix(layout): l'opération `move` préservait mal les champs du leaf (perdait `agent`)

//! Best-effort conversation inspection use case (CONTEXT §T7, Part A).
//!
//! [`InspectConversation`] enriches a resume popup with the *last topic* and a
//! *token indicator* read from a CLI's on-disk transcript. It is **best-effort
//! by construction**: it routes the agent's [`AgentProfile`] to the first
//! injected [`SessionInspector`] that [`supports`](SessionInspector::supports)
//! it, and *any* miss — no inspector at all, an unsupported profile,
//! [`InspectError::NotFound`], or [`InspectError::Read`] — degrades to **empty
//! details** (`last_topic: None, token_count: None`) instead of an error. The
//! resume must never be blocked by inspection.
//!
//! Extensibility (Open/Closed): adding a new inspectable CLI is *pushing one
//! more adapter into the `Vec`* at the composition root — no change here.
//!
//! Like [`super::lifecycle::LaunchAgent`], it resolves the agent from the
//! project manifest and its profile from the [`ProfileStore`], and inspects
//! against the agent's **isolated run directory** (the very `cwd` the CLI was
//! launched with) so the inspector points at the right transcript folder.

//! [`SnapshotRunningAgents`] — freeze, at close time, which agent cells still

//! When the IDE (or a single project) closes, every live PTY is about to be

//! its agent process was still running (`agent_was_running = true`) or had

//! - the persisted layouts store ([`super::store`]),
//! - the pure domain operation [`domain::LayoutTree::set_agent_running`],
//! - a [`LiveAgentRegistry`] liveness query.

//! T7 tests for the [`InspectConversation`] use case (best-effort conversation
//! inspection feeding the resume popup).
//!
//! Each port is faked in-memory:
//! - [`FakeContexts`] — an [`AgentContextStore`] holding a manifest seeded with
//! one agent,
//! - [`FakeProfiles`] — a [`ProfileStore`] returning a fixed profile list,
//! - [`FakeInspector`] — a [`SessionInspector`] whose `supports`/`details` are
//! configurable, so we can exercise: a supporting inspector returning details,
//! one returning `NotFound`, and the empty-`Vec` (no inspector) path.
//!
//! The contract under test (CONTEXT §T7 Part A): inspection is **best-effort** —
//! any miss (no inspector, unsupported profile, `NotFound`/`Read`) degrades to
//! empty details, never an error; only a genuine store failure errors.

//! [`ClaudeTranscriptInspector`] — a best-effort [`SessionInspector`] adapter
//! (CONTEXT §T6) for the **Claude Code** CLI.
//!
//! Claude Code records each conversation as a JSONL transcript under the user's
//! home directory:
//!
//! ```text
//! <home>/.claude/projects/<encoded-cwd>/<conversation-id>.jsonl
//! ```
//!
//! where `<encoded-cwd>` is the agent's working directory with its path
//! separators flattened to `-` (see [`encode_cwd`]). Each line of the `.jsonl`
//! is one JSON message object.
//!
//! This adapter is the **only** place that knows the Claude transcript shape:
//! it reads the file through the injected [`FileSystem`] port, extracts a
//! best-effort `last_topic` (the last `user` message text) and `token_count`
//! (the cumulative `usage` input+output tokens of `assistant` messages), and
//! returns the CLI-agnostic [`ConversationDetails`]. No Claude-specific type
//! ever leaves this module. Anything it cannot parse is skipped, never fatal.

/**
* T7 — the resume-conversation popup and its wiring in the layout grid.
*
* Two layers:
* 1. The presentational {@link ResumeConversationPopup} in isolation: status
* derived from `agentWasRunning` (never the inspector); enriched mode (topic
* + tokens) vs degraded mode (status only); the two action callbacks.
* 2. The grid wiring (`LayoutGrid` → `LeafView`): an agent cell that carries a
* persisted `conversationId` shows the popup **before** the Resume launch;
* "Reprendre" launches with the id; "Nouvelle conversation" clears the id
* first then launches without it. The reattach path (live PTY) never shows
* the popup.
*
* Because xterm bails under jsdom, `TerminalView`'s opener may not run in this
* environment — so the grid-level assertions render the popup by driving the
* opener directly is not possible. Instead we drive the popup through the
* component-level tests (deterministic) and assert the *opener wiring* by
* calling the exported component with stub gateways where the opener is invoked
* manually. To stay robust we focus the integration assertions on the popup
* presence + the two action effects, guarded on the opener having run.

/**
* T4b — closing the conversation-id persistence loop.
*
* Three layers, mirroring the SetCellAgent coverage:
* 1. The mock agent gateway assigns a fresh conversation id on a first launch
* (cell had none) and resumes (no new id) when one is passed in.
* 2. `MockLayoutGateway` applies the `setCellConversation` op, persisting/clearing
* the id on the leaf.
* 3. The grid wiring: when an agent cell launches and the backend assigns an id,
* `setCellConversation` is emitted so the next open resumes; and a leaf that
* already carries an id passes it back into `launchAgent`.
*
* As elsewhere (TerminalView.test), xterm may bail under jsdom, so the render-level
* assertions only fire when the opener actually ran.
