searchVirtualResources matched with JS RegExp, so an ssh:// (or other virtual) search diverged from local search for RE2-valid but JS-invalid patterns (e.g. (?i)x, [[:digit:]]) — throwing 'Invalid regex' or returning different matches even when local grep had already validated the pattern in a mixed scope. It now detects matched line numbers with native grep (the same RE2 matcher local search uses) and rebuilds the existing forward-only, range-trimmed context windows via buildVirtualMatches, so virtual/remote and local search share one dialect. Removed the now-dead JS-regex helpers (probeRegexDialect, compileVirtualRegex, searchVirtualResource{Lines,Multiline}, findLineIndex).
