delete superseded Python scripts
Seven scripts (1,658 lines) replaced by native Rust subcommands:
- journal-agent.py → poc-memory journal-enrich
- digest-link-parser.py → poc-memory digest-links
- apply-consolidation.py → poc-memory apply-consolidation
- daily-digest.py → poc-memory digest daily
- weekly-digest.py → poc-memory digest weekly
- monthly-digest.py → poc-memory digest monthly
- refine-source.sh → folded into journal-enrich
Also updated poc-journal to use Rust journal-enrich instead of
Python journal-agent.py, and cleaned up stale __pycache__.
Remaining Python (2,154 lines): consolidation-agents, consolidation-loop,
content-promotion-agent, bulk-categorize, retroactive-digest, store_helpers,
call-sonnet.sh, daily-check.sh — still active and evolving.
