Mark Eaton 87cb70b4fb v2 chunk 2b: cli format-notes subcommand and reformat_notes()
Wire the v2 note formatter into the CLI so it can be invoked on
real markdown drafts. The format-notes subcommand mirrors v1's
format subcommand: parser → formatter → reassemble, with concurrent
API calls.

src/cmos/cli.py:
- Import find_notes and format_note_entry alongside the existing
  v1 imports.
- Add reformat_notes(text, formatter, concurrency) that finds
  pandoc-style markdown footnote definitions via find_notes,
  formats each definition's text via the v2 note formatter (or
  an injected fake), and substitutes the formatted text back into
  the original line position. Non-definition lines preserved
  byte-for-byte. Returns text unchanged when no definitions found.
- Register the format-notes argparse subparser with the same
  --concurrency flag as v1's format.
- Dispatch args.command == "format-notes" to reformat_notes.
- Module docstring updated to document both subcommands.

tests/test_cli.py:
- 7 new tests for reformat_notes covering: in-place substitution,
  order preservation under concurrency, prose preservation,
  reference markers staying verbatim, no-op on empty input,
  trailing newline preservation.
- Extended test_python_dash_m_invocation_actually_runs_main to
  also assert "format-notes" appears in --help, catching accidental
  subcommand removal.

Path B integrity: formatter.py, note_formatter.py, parser.py,
linter.py, harness/score.py all unchanged. No LINTER_VERSION
bump. 96/96 v1 tests still passing. Total suite: 123/123.

Real-API end-to-end smoke test on a temp draft with 2 footnote
definitions: both reformatted byte-for-byte, prose and headings
preserved, ## Conclusion section after the notes preserved.

"""Tests for src/cmos/cli.py — end-to-end draft reformatting.
The CLI orchestrates parser → formatter → reassemble. Tests inject a fake
formatter so no API calls happen; the goal is to pin the glue logic, not the
LLM behavior.
v1: ``reformat_draft`` rewrites the ``## Bibliography`` section.
v2: ``reformat_notes`` rewrites pandoc-style markdown footnote definitions
in place by line number, preserving everything else byte-for-byte.

indistinguishable from a successful run that produced no output —
the worst kind of bug, since callers assume the pipeline ran. This
test forces the guard to exist by invoking the CLI as a subprocess
with --help and asserting argparse actually fired.
Also acts as a smoke test for both subcommands appearing in the
top-level help: catches the case where a future refactor removes
a subcommand registration without anyone noticing.
