docs(work): archive shipped template epics and PRDs

Move the 8 shipped template epics and their 9 PRDs (incl.
coverage-architecture) to docs/work/archive/{epics,prds}/ so dispatch
context and prioritization only see live Veect work. The state builder
already walks docs/work/epics/ + docs/work/prds/ only; the one work-CLI
script that matched archive paths (bump-updated-timestamps.mjs, staged
docs/work/**/*.md) now excludes docs/work/archive/ so archived content
stays byte-identical.

+## Goal
+
+Implement a four-layer enforcement stack — Claude hook, skill, pre-commit hook, sandcastle reviewer prompt — that makes every new runtime dependency in a feature- or core-tier package produce a permanent **library trace** at `docs/library-decisions/<YYYY-MM-DD>-<package-name>.md`. Rejection traces are first-class records. Codifies ADR-022.
+
+## Why
+
+The repo's narrow third-party surface is uncodified. New dependencies enter via `pnpm add` with no checkpoint. Three signals exposed the gap: a near-miss adding a build-time-only library, post-hoc ADR records (002/014/017), and a silent EU-data-residency risk from US-only SaaS defaults. The enforcement stack mirrors the 5-gate conformance pattern — same vocabulary, same agent feedback loop.
