v0.4.0

Minor Changes

• #7 bf047c9 Thanks @leejpsd! - Build-output cache seeding: seedBuildOutput() (new /seed entry point) and
  npx nextjs-cache-handler seed walk .next/ after a build and insert
  prerendered App Router routes (including PPR segment data), Pages Router
  routes, and fetch-cache entries into Redis in the handler's own record
  format — with NX semantics so entries already written by live instances are
  never overwritten. A fresh deployment's first requests are cache HITs
  instead of a regeneration stampede (verified on a real Next 16 app: cold
  server + seeded Redis → first request x-nextjs-cache: HIT). The
  RedisClientLike.set contract gains an optional NX flag.

• #7 1e57e03 Thanks @leejpsd! - New nextjs-cache-handler CLI (zero-dependency): init detects the Next.js
  version and Redis client, generates the handler wrapper shims, shows the
  next.config keys to add (never edits it), appends env templates, and injects
  the agent rules block into CLAUDE.md/AGENTS.md idempotently (--yes to
  apply, --skills to install the agent skill locally). doctor verifies
  Redis connectivity, inspects cache key namespaces, and runs a write/read
  round-trip — the first command an agent should reach for when debugging.

• #7 6cd5901 Thanks @leejpsd! - Opt-in push-based tag propagation (tagPubSub: true, plural handler):
  updateTags() publishes invalidations on a namespaced channel and every
  instance maintains a subscription on a dedicated duplicate connection,
  updating its local tag mirror in ~3 ms (measured cross-instance over real
  Redis with both redis@5 and ioredis) instead of waiting for the next
  refreshTags() scan (~seconds). The scan keeps running as the consistency
  safety net, so a dropped subscription degrades to the previous behavior —
  never to staleness. Cluster clients fall back to polling with a one-time
  warning. RedisClientLike gains optional publish/subscribe.
