inkhaven 1.4.19

//! MYTH-1 (M-P2) — the store over its own `.inkhaven/myth.duckdb`. Holds the
//! declared inventory (symbols / motifs / archetypes), the compiled highlight
//! vocab, the per-chapter density scan, motif occurrences, and check findings.
//! Reads `char.duckdb` / `dialogue.duckdb` at query time elsewhere; never writes
//! them. Audit: TEXT/INTEGER columns, `DefaultHasher` u64 hashes, RFC3339 TEXT
//! timestamps — not the RFC's `UBIGINT`/`TIMESTAMPTZ`/`BOOLEAN`.
