docs(agents): rewrite package map and conventions for Veect

AGENTS.md now describes the Veect control plane (ADR-027/028/029,
docs/product/ authority table, glossary Veect-domain vocabulary), with
the package map, boundary tags, and per-package conventions verified
against the filesystem (auth + 11 core + 3 tooling packages;
web-next/cms/storybook apps) and code examples drawn from the real auth
feature. Adds warning notes for known generator staleness — the
release-please per-feature registration that would collide with the
root-only v* tag policy, the pre-shipped trace overwrite hazard (zod
incident, restored in e4a3b65), the trpc template's removed
@trpc/react-query dep — and records the accepted warn-severity lint
backlog (~93 findings).

Per story amendments, the same slice prunes the dead "web-tanstack"
member from core-shared's app-tag unions (bind-otel-instrumentation.ts,
sentry/init-client.ts; tests retargeted to "web-next") and fixes the
stale app/feature tag lists in docs/architecture/overview.md. A warning
comment mirrors the release-please note at the generator call site; no
functional generator changes.
