Naiyuan Qing 6fafd86ecc fix(skills): harden import against invalid UTF-8 and binary files
PG rejects two byte patterns in a TEXT column. Both crashed real skill
imports we hit while assembling the template catalog:

- Embedded NUL (0x00) -> SQLSTATE 22021. Already stripped by
  sanitizeNullBytes, kept as-is.
- Other invalid UTF-8 (e.g. 0x91 — Windows-1252 smart quote in a skill
  whose author saved prose from Word). sanitizeNullBytes now also runs
  strings.ToValidUTF8 over the content so the second class no longer
  takes the whole import down.

For non-text payloads (images, fonts, archives, compiled binaries),
sanitization isn't the right fix — agents never read those as text,
and the bytes can't survive a TEXT column at all. addFile now skips
them by extension before the per-bundle cap counters tick, logging
the skip so an unexpected drop leaves a breadcrumb.

Function name kept for compatibility with the many call sites; both
behaviours are strict supersets of the original.
