reticulate 1.44.0

• Reticulate now clears its cache automatically every 120 days. Configure the interval
  in .Rprofile with: options(reticulate.max_cache_age = as.difftime(30, units = "days")).

• install_miniconda() now installs miniforge instead of miniconda (#1800, #1820).

• New helpers for reading and writing requirements files,
  py_write_requirements() and py_read_requirements() (#1846).

• Adds support for requesting Python versions with a wildcard pattern x.x.* such as ==3.12.* in virtualenv_starter(), py_require(), and related functions (#1825)

• Restored compatability with uv versions >= 0.8.0 (#1818).

• virtualenv_starter() now discovers Python installations managed by
  external uv installations (#1849).

• py_require() now gives a better message when a user erroneously declares
  a module from the Python standard library as a required package (@lazappi, #1788)

• Positron's reticulate integration will now be automatically enabled when
  the reticulate package is loaded in Positron (#1822).

• with() now forwards errors to Python context manager exit handlers
  (e.g., so database transactions can roll back cleanly) (#1840, #1841)

• Fixed !! in string literals being wrongly expanded to a %system magic in
  repl_python(). Added support for assigning %system command output to multiple
  variables via unpacking (#1844).
