Bumps the ci-tools group with 3 updates in the /.github directory: coverage, ruff and zizmor.

Updates coverage from 7.16.2 to 7.17.0

Release notes

Sourced from coverage's releases.

7.17.0

Version 7.17.0 — 2026-10-22

• Dropped support for Python 3.10.
• Binary wheels are now provided for iOS and Android. This allows the use of the optimized C tracer on mobile platforms.
• Fix: three or more levels of nested with statements could make a with line look like a branch with an exit that can never happen. Using the sys.monitoring core, these phantom branches were reported as partial. Other cores hid the problem but still counted the phantom branches in the total. Closes issue 1987.
• Fix: a comment or string that merely mentioned if True: or while True: could mark its line as a branch that is known to be partial, so a branch that never ran was reported as taken. These built-in patterns now only match at the start of the statement. Closes issue 2314.
• Fix: region detection missed functions defined in unusual places, such as else and except clauses. This is now fixed.
• Fix: recent versions of the lcov tool complain if the same function name appears more than once in a report. Python can have multiple same-named functions in a few ways, for example, getters/setters or conditionally defined functions. These are now disambiguated by adding a @<line number> suffix to the function name. Fixes issue 2335.
• Fix: The “Can’t combine statement coverage data with branch data” error now names the two data files it couldn’t combine. The error description in the docs now lists common causes and how to find the process that wrote the file.
• Fix: at coverage totals close to 0 or 100, the XML report could get incorrect line-rate values like 8.333e-05 or 1. This is now fixed, closing issue 2293 and issue 2294.
• Fix: a parallel data file saved more than once kept the hash of its first save in its file name. Combining could then skip it as a duplicate of another file that had the same data at that point, and delete it, losing the data recorded after the first save. Each save now updates the hash. This had been a problem since 7.13.1. Fixes issue 2338.
• Fixes for obscure but legal file names:
  • File names (and plugin names) can contain control characters, which are legal in POSIX paths but unsafe in reports: in XML 1.0 they make the document non-well-formed, and in a terminal they act as escape sequences (colors, title/clipboard sequences, cursor moves that forge output). Now the XML report, the text and Markdown summary reports, and coverage debug data replace non-printable characters in names. Printable names are unchanged.
  • A file pattern (from include, omit, or a [paths] alias) containing a newline sent the glob-to-regex translation into an infinite loop, hanging the process. Newlines in patterns are now handled like any other character.
• Fixes in the implementation of the C tracer:
  • If a plugin’s dynamic_source_filename method raised an exception, lines in that function could be recorded as belonging to a different file. Also fixed some minor memory leaks in the C tracer.
  • The refcount of None was mismanaged during function calls, including comprehensions. This was unlikely to cause an actual problem, but is now fixed. Thanks, Andrew Dalke.
  • The C tracer held borrowed references to dictionary values, which was unsafe on free-threaded Python. Now it takes its own references.
  • An internal error while recording a new file could be reported as a confusing SystemError instead of the actual exception.
• Performance: the text summary report (coverage report) held on to every file’s parsed source until it finished, so its memory use grew with the size of the project: ten times or more what 7.14 used on large projects. Now it keeps only what it needs to print. Fixes issue 2277.
• Performance: HTML reports should be about 5% faster to produce.
• Kept the political banner in the README. Closes issue 2344.
