This commit extracts the logic for mapping audio analysis results into
the `RecordingMeta` fields into a new, pure function
`analysis_to_meta_fields`. This improves testability by separating the
core mapping logic from logging and other side effects.
The previous implementation directly handled logging and conditional
logic within the `run` function. The new function encapsulates these
mapping rules, including handling finite values, silent audio, and error
propagation. The caller, `run`, is now responsible for logging any
analysis failures before calling the helper. Unit tests have been added
to verify the behavior of `analysis_to_meta_fields` in various
scenarios.
