v0.2.94

Fixed

• Spell/grammar popup priority on overlapping ranges — when NSSpellChecker and LanguageTool both covered the same text range, the web editor rendered both underlines but the click handler returned NSSpellChecker's result first, so clicking a blue-underlined word opened the spell menu instead of LT's grammar/style popup. SpellCheckService.check() now suppresses any NSSpellChecker result whose range overlaps an active LT result. Built-in mode (LT off) is unchanged.

Added

• .proofing DebugLog category — LT request/response instrumentation (disabled by default; enable when diagnosing coverage or filter balance).
• DebugLog.isEnabled(_:) — lets logging helpers early-return instead of running unconditional string/loop work on every scan.

Changed

• Proofing diagnostics simplified — gated logRequestBoundary, logResponseBoundary, and the dispatcher-level summary behind DebugLog.isEnabled(.proofing) so their NSString substring/replace and per-type counting loops no longer run on the MainActor every ~400ms when disabled.
• Deduplicated type-counting loops — extracted SpellCheckService.countByType(_:) -> TypeCounts to remove duplicated switch-on-String-type loops in SpellCheckService and LanguageToolProvider.
• Split parse-drop counters — ParseDiagnostics.droppedZeroLength split into droppedMissingFields (guard-let failure) and droppedZeroLength (length ≤ 0); log line reports both.
• LanguageToolProvider.check() refactor — extracted buildCheckRequest and diagnostic-logging helpers to stay under the cyclomatic-complexity limit.
• boundaryPreviewChars constant (200) replaces the magic number in boundary logging.
• Boundary-filter comment updated with measured note ("~20% of raw matches on prose with citations/footnotes/annotations") instead of the prior speculative claim.
