docs: remove the Finished./Finish. notebook-generation crutch

[Jammy2211]

Removes the Finished. / Finish. notebook-generation crutch from HowToFit — 1 occurrence: 1 trailing block.

Artifacts: 1 notebook regenerated.

Why

These trailing docstring blocks were a crutch against notebook generation "cutting off weird" when a script's last cell was not a docstring. That belief is obsolete: deleting the block and running the real add_notebook_quotes → ipynb-py-convert chain gives a complete, unmangled final code cell, and PyAutoLabs/PyAutoHands#214 adds test_script_ending_in_code_keeps_a_complete_final_code_cell to pin it. The crutch rendered as a pointless final markdown cell in every generated notebook.

Shapes handled

A blanket regex would be wrong — five distinct shapes exist and each needs different handling. The sweep used Python's own tokenize to locate the exact string token each occurrence lives in, because a line-based scanner cannot tell a narrative docstring's bare delimiter from a function docstring that opens with text on the delimiter line, and this corpus contains both.

Verification

• Every changed file compiles.
• black --check clean.
• Env declarations byte-identical before and after. Removing the word above an __Env__ section turns the canonical merged form into the standalone-fallback form; both are supported. Checked by running env_config.read_env_declaration on the old and new content of all 169 changed files across the series: 169 unchanged, 0 changed, 0 errors.
• CRLF preserved. Several of these repos ship CRLF .py files; the first attempt normalised them and rewrote whole files (~6000 line churn). The sweep reads and writes with newline="", so the diff is deletions only.
• No generated notebook contains a code cell with a literal # %% or ''', and no notebook has a Finish. markdown cell.

Merge order

PyAutoLabs/PyAutoHands#214 merges first — this repo invokes ../PyAutoHands/autohands/generate.py from the local checkout, so the regenerated notebooks here are only correct against that version.

Part of PyAutoLabs/PyAutoHands#211.
