feat: SET DELETED filtering, SEEK/LOCATE/CONTINUE, SET command codegen

Browse Source 
- 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)
