Allow styling of status, timing, and warnings text

[rolandwalker]

Description

Allow styling of status, timing, and warnings text per settings in ~/.myclirc. The new styles are off by default, just available to change.

Warnings styles represent a set of independent header, rows, etc. for the whole warnings table. It is not yet possible to style the borders of the warnings table.

Example of styling status text:

Example of styling the warnings table:

(Styling of the status and timings text is awesome, and I will use it right away. Status of the warnings table, not so much. It would be better with the borders included.)

Checklist

• I added this contribution to the changelog.md file.
• I added my name to the AUTHORS file (or it's already there).
• To lint and format the code, I ran

  uv run ruff check && uv run ruff format && uv run mypy --install-types .

1. Regression: timing lines are no longer written to audit log

• In mycli/main.py, output_timing() prints directly with print_formatted_text(...) but never calls self.log_output(...).
• Before this PR, timing output used self.echo(...) (at the two call sites now changed), which did log via log_output.
• Impact: users with --logfile lose timing entries unexpectedly.
• Fix: add self.log_output(timing) inside output_timing() before printing.

2. warnings.status / warnings.timing settings are currently ineffective

• New config keys are added in mycli/myclirc, but warning status still renders with class:output.status in mycli/main.py, and there is no warnings-specific timing path.
• Impact: documented/visible settings appear supported but don’t affect output.
• Fix: either wire warning-status/timing rendering to warning classes, or remove/defer these keys to avoid misleading config surface.

3. Missing tests for introduced behavior

• PR only updates config fixture (test/myclirc); no tests validate:
  • styled status/timing rendering paths,
  • warnings-style remapping path (is_warnings_style=True),
  • timing logging regression case.
• Recommend adding focused unit tests in test_main.py / test_clistyle.py for these new code paths.

Couldn’t run tests in this environment (pytest/uv not available), so review is static-analysis only.
