deps(python): update coverage requirement from >=7.0 to >=7.16.1

[dependabot]

Updates the requirements on coverage to permit the latest version.

Release notes

Sourced from coverage's releases.

7.16.1

Version 7.16.1 — 2026-09-13

• Fix: when the body of an irrefutable case (like case _:) is entirely excluded, the case line is now excluded too, just as an excluded else: body removes the else: line. Previously the case line was left behind and reported as missing. Closes issue 1563 with pull 2269.
• Fix: using CoverageData.update() twice on an in-memory database would fail, as described in issue 2279. This is now fixed.

Version 7.16.0 — 2026-08-28

• When combining files, now path separator slashes will automatically be converted to the local file system style. This makes it less necessary to define [paths] configuration to combine data across operating systems. Fixes issue 2266_.

• The :meth:.Coverage.switch_context method now returns the previous context.

• Fix: previously, a [paths] pattern would be replaced everywhere in a file path when it was only meant to be replaced once, in the leading portion of the path. This is now fixed, in pull 2268_.

• Fixes to validation of options and configuration settings:

  • Negative precision settings now always cause useful error messages (pull 2261_).

  • An invalid regex in the --contexts option (or the [report] contexts setting) reported a confusing "Couldn't use data file ...: user-defined function raised exception" error. Now it raises a proper configuration error naming the bad regex, like other regex settings do (pull 2262_).

  • Non-string values in TOML configuration settings now produce a helpful error message instead of a traceback. This affects list settings whose elements aren't strings (like omit, exclude_lines, or a [paths] entry), file settings like data_file, and any wrong-typed value in the [paths] section (pull 2263_).

  • coverage run refuses run-affecting command-line options like --branch alongside --concurrency=multiprocessing, since they can't

Closing as a no-op. Floor-only bump on docker/requirements.txt; the image already installs coverage 7.16.1, so nothing installed changes. Policy tracked in #512.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
