When the input has a header but no data rows, the insert path never
creates the table - the row loop has nothing to feed into the first
insert. The post-insert tracker.transform call then asserts the table
exists and blows up:
AssertionError: Cannot transform a table that doesn't exist yet
Reported in #702 with the exact fix in the body. Guard the transform
on db[table].exists() so an empty CSV is just a no-op, matching what
--detect-types already does for a zero-byte CSV (no header either).
Closes#702.
Signed-off-by: Charlie Tonneslan <cst0520@gmail.com>
The `--detect-types` option is now automatically turned on for all commands that deal with CSV or CSV.
A new `--no-detect-types` option can be used to have all columns treated as text.

The --functions option now accepts:
- File paths ending in .py (e.g., --functions my_funcs.py)
- Multiple invocations (e.g., --functions foo.py --functions 'def bar(): ...')
- Inline Python code (existing behavior)
Implementation follows the same pattern as llm's --functions flag
(simonw/llm@a880c123).
Changes:
- Added multiple=True to --functions Click option in query, bulk, and memory commands
- Modified _register_functions() to detect and read .py files
- Updated _maybe_register_functions() to iterate over multiple function sources
- Removed unused bytes/bytearray handling
- Added comprehensive tests for file paths and multiple invocations
- Updated documentation with examples

Closes#577
This should solve all sorts of problems seen by users of platforms that throw errors on writable_schema.
Also added `add_foreign_keys=` and `foreign_keys=` parameters to `table.transform()`.

- Uses `sqlean` in place of `sqlite3` if `sqlean.py` is installed
- Uses `sqlite-dump` if available and `conn.iterdump()` does not exist
- New `with db.ensure_autocommit_off()` method for ensuring autocommit is off, used by `enable_wal()` and `disable_wal()`.
