v0.9.0

0.9.0 - 2026-05-20

• Breaking: SQLite/Turso adapters now take a databaseUrl instead of a caller-owned database handle. Sledge owns the connections it opens and closes them with the ledger.
• Breaking: query and indexer implementations now receive the Sledge-provided storage scope as their first argument. Ambient ledger.query(...) receives an ambient read scope; event projection actions.query(...) and actions.index(...) receive the event transaction scope.
• Remove ledger-level busy retry configuration. Conventional SQLite adapters keep a single writer gate internally; busy lock conflicts from other connections fail fast.
• Reject plain :memory: database URLs because they cannot support the multi-connection storage model.
• Require the better-sqlite3 adapter to open databases in WAL journal mode so owned reader connections do not block writer commits.
