oyi77 819c0762b9 fix(compression): address PR review — multi-part msg safety, preservation $& fix, rule name sync, no-op rule removal ...

4 fixes from Gemini Code Assist PR #1689 review:

1. HIGH: Multi-part message content duplication — skip array-content
   messages instead of joining+replacing all text parts with compressed
   result, which caused content duplication (e.g., [A,B] → [comp(A+B), comp(A+B)])

2. HIGH: String.prototype.replace $& vulnerability — use arrow function
   callback instead of string arg in restorePreservedBlocks() to prevent
   special replacement patterns ($&, , etc.) from corrupting restored
   content containing code, URLs, or file paths

3. HIGH: UI/backend rule name mismatch — ALL_CAVEMAN_RULES in
   CompressionSettingsTab.tsx now uses actual backend rule names
   (polite_framing, hedging, verbose_instructions, etc.) instead of
   fabricated names (hedging_disclaimer, redundant_please, etc.)
   that would break the skip-rules feature

4. MEDIUM: Remove no-op turn_marker rule — pattern /^$/g matches only
   empty strings and replaces with empty string, achieving nothing.
   Removed from CAVEMAN_RULES; total count now 29 (was 30).

Tests: 72/72 pass, typecheck: 0 errors, lint: 0 errors
