The CLI documentation had a handful of sections with notes linking to the
equivalent Python API feature. Extend that pattern to every CLI section
with a Python equivalent, and add matching 'In the CLI:' notes to the
Python API documentation linking back to the corresponding CLI command.

Type detection is the 4.0 default for CSV/TSV data, and the detected-type
transform ran even when the target table already existed - inserting a
CSV into a table with a TEXT zip column converted the column to INTEGER,
corrupting values with leading zeros ('01234' became 1234) with no
warning. Detected types now only apply to tables the command created.

- table.extract() and the sqlite-utils extract command now skip rows
where every extracted column is null: the new foreign key column is
left null and no all-null record is added to the lookup table. Rows
with at least one non-null extracted column are extracted as before.
- The extracts= option to insert() and friends keeps None values as
null instead of creating a lookup record for them - previously each
insert batch added a duplicate null row to the lookup table.
- table.lookup() compares values using IS rather than = so lookup
values containing None match existing rows correctly, instead of
inserting a duplicate row on every call.

Queries returning duplicate column names - e.g. joins between tables
sharing column names - silently lost values because rows were built
with dict(zip(keys, row)), where the last duplicate wins.
Later occurrences are now renamed with a numeric suffix: id, id
becomes id, id_2 - skipping any suffix that would collide with a
real column in the same query.
The new utils.dedupe_keys() helper transforms the key list once per
query, so the per-row dict construction is unchanged and there is no
measurable performance impact.
Applied in Database.query() (including the PRAGMA and RETURNING
paths), Table.rows_where(), Table.search() and the CLI's JSON output.
CSV, TSV and table output keep the original duplicate headers.

This now works:
echo '{"date": "13th January 2025"}' | sqlite-utils insert dates.db dates -
sqlite-utils convert dates.db dates date r.parsedate
sqlite-utils rows dates.db dates
Previously the command would have been:
sqlite-utils convert dates.db dates date 'r.parsedate(value)'
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.
Closes#679
Closes#659
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
