* Implement migration safety rules: - MIG001: Warn on CREATE INDEX without CONCURRENT. - MIG002: Warn on ALTER TABLE ADD COLUMN NOT NULL without DEFAULT. - MIG003: Warn on ALTER TABLE ADD CONSTRAINT without NOT VALID. * Implement naming conventions rules: - NAM001: Warn on non-snake_case table names. - NAM002: Warn on non-snake_case column names in CREATE TABLE. - NAM003: Warn on non-snake_case function names. * Add test fixtures for all new rules.
