session-memory: friction assessment + hardened catalog (WP-0005 T03)

Re-ran ingest->detect with the quality filter + infra signals over real local
sessions (72 captured -> 27 real). Purged the false-positive 'abandoned' catalog
entry and re-curated; catalog now carries tool_thrash/schema_thrash/infra_overhead
patterns. docs/ASSESSMENT-infra-friction.md ranks the friction: ~17.6% of real
tool activity is hub/task/schema plumbing (State Hub 10.3%, one session 231 calls;
ToolSearch in 81% of sessions). Validates the CLI/MCP-skill hypothesis as top-2;
recommends a State Hub skill (front-load schemas + batched writes) + bulk hub ops.
Workplan finished; suite 88/88.
