feat(skills): pql-board — clide-style ticket board as a stable claude.ai Artifact

tooling/pql-board-html: self-contained interactive board snapshot from
pql-native JSON (ticket list --full + batched --with-blockers for non-terminal
tickets + plan status) — status-grouped rail with filter/type chips, ticket
dossier with status pills, dep/children chips, deep links, keyboard nav;
clide's visual identity (amber on warm near-black, mono data type). The
/pql-board skill regenerates and redeploys to the canonical artifact URL so
the user's open tab survives refreshes across sessions.

+  Refresh (or first-create) the pql ticket-board Artifact — the clide-style
+  two-column board snapshot hosted at a stable claude.ai URL. Use when the user
+  says "refresh the board", "update the pql board", "/pql-board", or asks to see
+  the ticket board in the desktop app.

+# pql Board Artifact
+
+The board is a self-contained interactive HTML snapshot of the pql ticket store
+(status-grouped rail, ticket dossier with dependencies/children, filter,
+deep-links), deployed as a claude.ai Artifact. Artifacts are network-sandboxed,
+so the page is a **snapshot** — this skill regenerates and redeploys it.
+
+**Canonical URL (redeploy target — keep stable so the user's open tab survives):**
+
+    https://claude.ai/code/artifact/0064e59d-84a9-4a31-a830-f7d677df9d92
+
+## Workflow
+
+1. Generate the fragment (from the repo root; pql must resolve to this vault —
+   run from the MAIN checkout, not a worktree):
+
+   ```bash
+   tooling/pql-board-html <scratchpad>/pql-board.html
+   ```
+
+   The script pulls `pql ticket list --full`, batch-fetches blocker edges for
+   non-terminal tickets, and `pql plan status` for the header. Output is an
+   Artifact-ready fragment (no doctype/html/head/body).
+
+2. Deploy with the **Artifact tool**, always passing the canonical URL so the
+   existing artifact updates in place (a fresh session without `url` would mint
+   a new address and orphan the user's tab):
+
+   - `file_path`: the generated file
+   - `url`: the canonical URL above
+   - `favicon`: `🗂️` (keep stable — the user finds the tab by it)
+   - `label`: short, e.g. `board-YYYY-MM-DD`
+
+3. Reply with one line: ticket/edge counts from the generator's stdout + the
+   URL. The user reloads their tab.
+
+## Notes
+
+- If the Artifact call 409s (another session touched it), reconcile then retry
+  with `force` only if intentionally replacing.
+- If the canonical artifact was deleted and a new URL gets minted, **update the
+  URL in this skill file** in the same turn and commit it.
+- The generator is `tooling/pql-board-html` (python, pql-native JSON only).
+  Known scope limits vs clide: no decisions view, no kanban columns, no live
+  editing. Dep edges cover non-terminal tickets only — if pql grows
+  `ticket list --with-blockers`, simplify the script (candidate upstream FR
+  per the pql-gaps-go-upstream rule).
+- Companion interaction surface: the visualize widget (`show_widget`) supports
+  `sendPrompt()` — for in-chat quick actions (refresh button, WIP strip); see
+  the session pattern, not this skill.
