Executor: run parsed SQL against storage

[pszymkowiak]

Implement the query executor (src/executor/mod.rs):

• Executor struct wrapping a &mut Pager
• execute(Statement) -> Result for CREATE, DROP, INSERT, UPDATE, DELETE
• query(Statement) -> Result<Vec<Vec>> for SELECT
• WHERE clause evaluation: eval_bool(), eval_value() on rows
• ORDER BY: sort results by column
• LIMIT: truncate results
• Support for SELECT * and SELECT col1, col2

Must handle: column lookups by name, type comparisons, AND/OR logic.
