feat: SET DELETED filtering, SEEK/LOCATE/CONTINUE, SET command codegen
- skipFilter: skip deleted records in GoTop/GoBottom/Skip when SET DELETED ON - hbrdd.IsSetDeleted callback: avoids circular import hbrdd→hbrtl - Parser: capture ON/OFF for boolean SET commands (DELETED, EXACT, SOFTSEEK, etc.) - Parser: capture TO expr for SET DATE/DECIMALS/EPOCH - Gengo: emit proper t.Do() calls for 11 SET toggles + 3 value SETs - stmtSet: was stub (skipToEOL), now calls parseSet() - RTL: register 11 SET toggle functions (SETDELETED, SETEXACT, etc.) - RTL: DBLOCATE/DBCONTINUE for sequential search - RTL: DBSETFILTER/DBCLEARFILTER/DBFILTER - PadL/PadR: support 3rd param fill character - Area interface: added SetFound, SetLocate, LocateBlock, filter methods - MemRDD: implements new Area interface methods - Comprehensive PRG test: test_search.prg (7 test suites all pass) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
