chore(skills): refresh clide from canonical + preserve d2/frame0 tailoring (T-1101)

clide SKILL.md re-synced to the clide repo's canonical copy (picks up the dock/D-87 slot; de-forks). d2-diagram/frame0-wireframe/skill-create deletions landed in the prior commit; their repo-specific tailoring is preserved in docs/design/diagram-wireframe-conventions.md. Part of T-1099.

+# Diagram & wireframe conventions (Settled Reach)
+
+The `/d2-diagram` and `/frame0-wireframe` skill *mechanics* now live at user scope
+(`~/.claude/skills/`), de-contaminated of repo-specifics. This file preserves the
+Settled-Reach tailoring the local skill copies carried, so it isn't lost when they're
+deleted (CLAUDE-CLEANUP §2 / T-1101).
+
+## d2 diagrams (`/d2-diagram`)
+
+**Output taxonomy:** `.d2` source + `.png`/`.svg` renders under
+`docs/diagrams/{category}/{name}.d2` — categories in use: `architecture/`, `ui/`,
+`entity/`. Create/update a diagram whenever a D-record is added or modified.
+
+**Agent routing** (who to task with a diagram, by domain):
+- **Qatux** — architecture decision records, system-overview + data-flow diagrams.
+- **Tyre** — IPC bridge, ECS system flow, chunk-loading pipeline, perception internals.
+- **Araminta** — UI navigation flow, screen transitions, component hierarchy.
+
+## Frame0 wireframes (`/frame0-wireframe`)
+
+**Output taxonomy:** wireframe JSON (source of truth) + exported PNG under
+`docs/design/wireframes/{category}/{name}.json` — categories include `insert/`
+(neural-insert HUD), `dialogue/`, etc. Palette/style source is
+`docs/design/visual-grammar-v01.md`.
+
+**Agent routing:** Araminta (art direction / visual consistency) owns wireframe review;
+Stig (UI dev) consumes them for implementation.
