feat(io): support SCIEX WIFF import

[nmrtist]

Summary

• Add a pure-Rust importer for validated legacy SCIEX .wiff and paired .wiff.scan acquisitions, including sample identity, experiment and cycle structure, spectra, precursor metadata, and per-experiment TIC channels.
• Preserve duplicate sample names and empty or zero-TIC DDA slots, reject missing companions and unrecognized layouts, and provide conversion guidance for unsupported .wiff2 and .timeseries.data inputs.
• Integrate WIFF imports with desktop file discovery, CLI output, dataset provenance, and TIC handling, with synthetic test coverage and aligned English and Simplified Chinese documentation.

Validation

• cargo pr-check
• npm run build from docs/
