chore(template): clean-slate template snapshot from bb4a0c7

Curated, product-agnostic snapshot of the post-story-04 tree: demo
content deleted, auth-only reference feature, web-next shell, all gates
green. Product-specific docs, ADRs 027-029, PRDs/epics/archive, editor
library traces, and product naming are curated out; generic template
repairs (coverage provider devDeps, root test:coverage script, live
lint fixes, root-only release-please) are kept. See TEMPLATE.md for
provenance, curation list, and usage.

+name: grill-me
+description: Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when the user wants to stress-test a plan, get grilled, or mentions "grill me". Use grill-with-docs instead when the plan should cross-check against ADRs + glossary + manifests.

+
+Interview the user relentlessly about every aspect of this plan until you reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer.
+
+Ask the questions **one at a time**, waiting for feedback before continuing.
+
+If a question can be answered by exploring the codebase, explore the codebase instead. Useful shortcuts in this repo:
+
+- `pnpm work status` — current epics and ready stories
+- `cat packages/<feature>/src/feature.manifest.ts` — declared use cases / events / audits
+- `ls docs/decisions/` — ADRs by number
+- `pnpm fallow` — dead exports, dupes, complexity hotspots
+- grep manifests across all features: `grep -r "publishes:" packages/*/src/feature.manifest.ts`
+
+When grilling pulls in ADR / glossary / manifest cross-checks and you want to update those docs inline, switch to `grill-with-docs` instead.
