add STRICT table mode support for SQLite

[elithrar]

Adds .strict() method to sqliteTable() for creating SQLite STRICT tables.

const users = sqliteTable('users', {
  id: int('id').primaryKey(),
  name: text('name'),
}).strict();

Generates: CREATE TABLE users (...) STRICT;

Changes

• .strict() chained method on sqliteTable (like enableRLS() pattern)
• isStrict in schema serialization and DDL generation
• introspection support for existing STRICT tables
• runtime warnings for invalid STRICT column types (valid: INT, INTEGER, REAL, TEXT, BLOB, ANY)
