Add separate migration logging, logmigr callback, and log= override
...
- Split transaction logger (kanta.changes) and migration logger (kanta.migrations).
- Migrations.apply() now returns MigrationResult instead of logging.
- Kanta.open() emits one info summary per DB and debug transaction per migration.
- Add open(log=...) to suppress/redirect default migration logging.
- Add @kanta.logmigr callback for custom migration logging/summaries.
- Add transaction(log=...) to suppress/redirect transaction logging.
- Update tests for the new MigrationResult API and logging behaviour.

Revised migration context: don't store changerecord unless something was changed, and always snapshot if and after changes done.

Stricter versioning: always store migrate version record, file must be within versions included in migrations. Log only for migrations that made changes. Allow deleting older migration functions when no longer required.

Add kanta.ctx SimpleNamespace for user variables. This is passed to migration functions if they take a second argument. Remove the old MigrationCtx system.

Add read only mode that doesn't use locking. Useful for inspection while the database is in use or when no changes are intended (except in RAM).
