Add PF2e equipment display with detail popovers in stat blocks

Extract shared DetailPopover shell from spell popovers. Normalize
weapon/consumable/equipment/armor items from Foundry data into
mundane (Items line) and detailed (Equipment section with clickable
popovers). Scrolls/wands show embedded spell info. Bump IDB cache v7.

+
+## Instructions
+
+Commit current changes, create the next version tag, and push everything to remote.
+
+### Step 1 — Commit
+
+Use the `/commit` skill to stage and commit changes. Pass along any user arguments as the commit message.
+
+```
+/commit $ARGUMENTS
+```
+
+### Step 2 — Tag
+
+Get the latest tag and increment the patch number (e.g., `0.9.27` → `0.9.28`). Create the tag:
+
+```bash
+git tag --sort=-v:refname | head -1
+```
+
+```bash
+git tag <next-version>
+```
+
+### Step 3 — Push
+
+Push the commit and tag to remote:
+
+```bash
+git push && git push --tags
+```
+
+### Step 4 — Verify
+
+Confirm the tag exists on the pushed commit:
+
+```bash
+git log --oneline -1 --decorate
+```
+
+## User arguments
+
+```text
+$ARGUMENTS
+```
+
+If the user provided arguments, treat them as the commit message or guidance for what to commit.

 - **TypeScript strict mode** with `verbatimModuleSyntax`. Use `.js` extensions in relative imports.
 - **Branded types** for identity values (e.g., `CombatantId`). Prefer immutability/`readonly` where practical.
+- **Reuse UI primitives** — before creating custom interactive elements (buttons, inputs, selects, dialogs), check `apps/web/src/components/ui/` for existing components with established variants and hover styles.
 - **Domain events** are plain data objects with a `type` discriminant — no classes.
 - **Tests** live in `__tests__/` directories adjacent to source. See the Testing section below for conventions on mocking, assertions, and per-layer approach.
 - **Quality gates** are enforced at pre-commit via Lefthook (parallel jobs). No gate may exist only as a CI step or manual process.
