session-memory: error-body mining into digest (WP-0006 T01)

build_digest now extracts normalized error fingerprints + samples from failed
events (error kind + failing tool_result bodies) into a durable error_snippets
list — paths/numbers/uuids/addrs stripped so the same error collapses to one
fingerprint with a count; Python traceback header skipped in favour of the real
exception line. Durable in Tier 2 (survives Tier 1 eviction). SCHEMA_VERSION ->
2 (re-ingest needed to populate). 7 new tests; suite 95/95 green.
