v0.1.9 — Smart caching and clearer request logs

• Added opt-in bridge-level cache rules on top of Next.js server fetch, with per-request cache overrides and the existing raw cache/next options preserved.
• Added automatic endpoint cache tags plus revalidateApiCache, revalidateCache, and expireCache helpers for targeted refresh after mutations.
• Added truthful cache-policy metadata to pretty and structured logs without claiming unsupported cache hit/miss detection.
• Replaced the @API prefix with the compact ↗ request identity.
• Simplified terminal colors: request identity/path use one cyan accent, status is semantic, and timing/size/cache metadata is gray.
• Expanded packed production E2E coverage to verify rule-based caching, live overrides, and endpoint invalidation across supported Next.js versions.
