Ben e24614db22 blog: Haystack persistent memory (drop-in tools + auto-recall wrapper) (#2147) ...

* blog: add Haystack persistent memory integration post

Walkthrough of hindsight-haystack — two integration modes:
- create_hindsight_tools() returning a list[Tool] for an Agent
- HindsightMemoryWrapper, a Toolset subclass with auto_recall and
  auto_retain that runs the memory work before/after each turn.
Plus the three memory primitives (retain/recall/reflect) and the
include_* flags to drop any subset.

Every concrete claim verified against the README and
hindsight_haystack/tools.py:
- Package name + version (0.1.0)
- Python >= 3.10, haystack-ai >= 2.12.0, hindsight-client >= 0.4.0
- Exported names from __init__.py
- create_hindsight_tools() and HindsightMemoryWrapper signatures
- "Use toolset.run(agent, ...) not agent.run(...) for auto behavior"
- configure() shape and acceptable kwargs

Underlying integration unit tests: 83/83 passing (3 e2e skipped for
lack of API keys in CI sandbox).

Cover is a placeholder (Codex art) for now; swap before merging.
