Sprint 280: Cross-language step + breakpoints (steps 1928–1932)

CrossLanguageStepOverHandler, CrossLanguageStepIntoHandler, ASTNodeBreakpointMapper, BreakpointSyncOrchestrator — 26/26 tests pass. Integration step 1932: Go+TypeScript poly-API round-trip verified. Metrics: 7 whetstone calls, 5587 tokens. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

+// Step 1931: BreakpointSyncOrchestrator
+//
+//  t1: addToAll sets breakpoint in every language in sourceMap
+//  t2: syncBreakpoint/activeLanguages returns active languages for node
+//  t3: removeFromAll removes all languages for a node
+//  t4: totalActiveBreakpoints sums across all nodes
+//  t5: mapper() accessor; deactivating via mapper reduces totalActive
