fix(skills): Recover chips reuse original session name; batch fans to one chip each

Two refinements to the summon recover-chip convention:
- Chip title = the original session name verbatim (e.g. "revoicing"), not a
  "Recover ..." label, so a recovered session reads as a continuation of the
  original in the Desktop sidebar rather than a new errand.
- Batch recover (multi-select) sends a single prompt that fans into one chip
  PER session — each recovering independently in its own project root — not
  one mega-chip. Documented explicitly.

Updates per-card + batch recover sendPrompt wording and the SKILL.md
in-chat recover convention.

 1. Run **`summon pick --json --rich`** with a **generous window** (e.g. `--days 30`; add `--cwd`/`--title` filters as asked) and parse the envelope (schema `claude-mods.summon.pick/v2`). `--rich` costs one transcript read per session and adds the per-card display metrics; the widget has its own client-side "last X" age filter (24h/3d/7d/30d/all), so the user narrows in-widget without a CLI re-run.
 2. Render [`assets/picker-widget.html`](assets/picker-widget.html) via the `show_widget` tool: drop the envelope's `data` array straight into the `S` array inside the marked `<script id="D">` block — the widget consumes the pick/v2 **objects verbatim** (keys documented in the template header). Archived sessions are hidden by default (a "show archived" toggle reveals them); cross-account copies dedupe by `sessionId`. Each card shows a **context-usage donut + token count** (last-turn occupancy vs the session's window — 200k or 1M, auto-detected from peak), an **activity-density strip** (24 buckets over the session's lifetime), and chips for model/effort, age, turns, messages, tool calls, on-disk size, and duration, plus **grid/list** and **sort** controls. `firstAsk` is the mechanical opening ask; you MAY replace it with a distilled one-liner by setting a `summary` field on the row before injecting.
 3. Act on the `sendPrompt` callbacks the widget fires. Per-card `↗ summon` and `⟳ recover` (and the footer's "Recover/Summon selected") are worded to be **spawned as background chips** — when one arrives, call `spawn_task` (one chip per session) rather than doing the work inline, so the user's current turn keeps flowing:
-   - **"Recover … as a background chip"** → one `spawn_task` per session, with the chip `cwd` set to the session's **project root** (strip any `\.claude\worktrees\<name>` suffix). Word the chip prompt so the chip *is* the recovered session: it reads the original transcript (resolve via `summon recover <id>` / the wrapper→transcript logic), writes a hand-off brief, and **resumes the work in place** in the project folder. The chip must **not** spawn a further chip and must **not** open the original worktree path as a separate session — that path is reference-only, for locating the branch and any in-progress changes. (The failure mode this prevents: a chip prompt that says "start a fresh session there" plus a worktree path makes the recovering chip spawn a *second* chip into the worktree. The chip already **is** the fresh session — tell it to continue, not to spawn.)
+   - **"Recover … as a background chip"** → one `spawn_task` per session (the batch button sends a single prompt listing all selected — fan it into one chip **per session**, not one mega-chip, so each recovers independently in its own project folder). For each chip:
+     - **Title = the original session name, verbatim** (e.g. `revoicing`) — never a `Recover "…" session` label. The chip should look like a continuation of the original in the sidebar, not a new errand.
+     - **`cwd` = the session's project root** (strip any `\.claude\worktrees\<name>` suffix).

    - **"Summon (copy) these…"** → transfer flow: `summon` with `--select` for exactly those sessions, `--dry-run` preview first, then the real run once the user confirms.
    - **"Peek session…"** → `summon --peek <id>`.
