Log Message:
py-mercurial: update to 6.9.

Update test status, two fixed, but a new core dump in test-locale.t, see
https://bz.mercurial-scm.org/show_bug.cgi?id=6948

Backwards Compatibility Changes

    This release drops support for Python 3.6 and 3.7.

    Starting with this release and hopefully for the forseeable
    future, we are now building wheels for most architectures.

    Python 3.13 changed how it handles docstrings (namely removing
    uniform leading whitespace for every line), which forced us to
    align the representation of our help text with this new behavior
    across all versions. Due to this and a lack of time and expertise
    from contributors, a lot of existing translations could be
    missing. The effort of i18n in general has died down many years
    ago, but if this matters to you, feel free to send your
    contributions.

New Features

    exchange: improve computation of relevant markers for large repos
    Add a Rust fast-path to speed up update (also for clone) from null (up to 4x \ 
faster)

    The branchmap's performance was improved
