Detailed Description

FilterValidator for Wireshark display filters.

validate() compiles the expression with dfilter_compile_full() and maps the result to the FilterEdit syntax states:

empty -> Acceptable (host shows Empty, no tint)
compiles cleanly -> Acceptable (Valid)
compiles with a warning or a deprecated token -> Acceptable with a non-empty Detail::deprecatedToken (host shows Deprecated/amber)
fails with DF_ERROR_UNEXPECTED_END -> Intermediate (still typing; never red)
fails otherwise -> Invalid, with the error message and location stashed in Detail so the host can render lastErrorFull().

Synchronous, like the capture validator: it runs on the host widget's debounce and reads lastDetail() immediately afterwards.
