- selecting an EF now renders an info block between the File: title and
the contents: FID, file type, size, record length/count (nulls skipped)
followed by the decoded FCI via the existing profilerFciPreviewItems()
decoder (no raw hex), matching the snapshot detail view
- pysimFsInfoHtml() is pure and reused by pysimFsClickFile(); the [LF]
shorthand stays in the title; custom files get the same metadata from
the temporary select probe
- tests: pysimFsInfoHtml in profiler.test.js (full response, missing
fci_hex, skipped nulls) and a structural check for #pysim-fs-info;
help EN/RU and READMEs updated; SW cache v119 -> v120.
