Byte-identical bodies moved out of hermes_cli/kanban_db.py into four sibling
modules, re-exported from the origin so kanban_db.<name> keeps resolving and
stays the single monkeypatch target; origin-resident helpers are reached via a
late-bound _kb namespace. AST-identity verified for all 329 moved symbols; SQL
statement multiset parity vs base. Three source-inspection tests repointed at
kanban_db_dispatch; the _add_column_if_missing alias test now imports the real
owner (hermes_cli.sqlite_util).
