Codex 9fe989b502 malkhut(perf): DuckDB in-memory materialization — sub-µs reads, zero DuckDB overhead

Architecture: DuckDB for persistence + full in-memory materialization for reads.
All reads served from Python dicts (sub-microsecond). DuckDB only hit on writes.

Performance evolution (get_asset benchmark):
  V0 (raw DuckDB):    876µs per call
  V1 (LRU cache):     2.3µs per call (380x)
  V2 (in-memory):     0.2µs per call (4380x)

All reads now sub-microsecond:
  get_asset:      0.2µs (was 876µs)
  query(blockian): 6.6µs (was 2.2ms)
  query(sector):   6.6µs (was 3.2ms)
  exchange lookup: 12.5µs (was 1.5ms)
  full scan:       5.9µs (was 1.8ms)
  behavior:        0.4µs

Write path: sync_from_profiles batch-inserts all data, then materializes
into Python dicts. Resync: 76ms (was 210ms, 2.8x faster).

Data integrity: DuckDB WAL provides crash recovery. In-memory dicts are
reconstructed from DB on every sync/close-reopen cycle. Zero data loss.
