Implicit class_path provenance says what implied it

[mauvilsa]

What does this PR do?

• Provenance of a subclass class_path that was not given, but derived from the type (e.g. a config with only init args such as {"opt": {"lr": 0.5}}), is now shown as implicit and what implied it, e.g. # implicit, from config file cfg.yaml:1, instead of being attributed directly to that source as if it had been given there.
• Applies to command line arguments, config files, environment variables, defaults, lists of subclasses and callables returning a class.

Before submitting

• Did you read the contributing guideline?
• If you used a coding agent, did you fully understand and validate all generated code and ensure it follows the contributing guidelines?
• Did you update the documentation? (readme and public docstrings)
• Did you write unit tests such that there is 100% coverage on related code? (required for bug fixes and new features)
• Did you verify that new and existing tests pass locally?
• [n/a] If this is a bug fix, did you verify that the tests fail without the code fix?
• Did you make sure that all changes preserve backward compatibility?
• Did you update the CHANGELOG including a pull request link? (not for typos, docs, test updates, or minor internal changes/refactors)

Confidence Score: 5/5

[Medium risk] Tracks where implicit class paths came from in config parsing.

The PR appears safe to merge; no actionable defect was established.

Summary

The PR distinguishes subclass class paths inferred from a type from class paths explicitly supplied by a user.

• Carries the source that implied a class path through provenance propagation and renders it in provenance comments.
• Documents the output and adds tests for defaults, config files, command-line arguments, lists, and callable return types.
