b7028791d6 fix: 5 seek/dbf bugs — 77/77 thorough Harbour compatibility 
1. SOFTSEEK: use idx.CurRecNo() for positioning (was checking recNo > 0)
   - SEEK with SET SOFTSEEK ON now positions at next higher key
   - SEEK command reads SET SOFTSEEK at runtime (was compile-time only)
   - rtlDbSeek defaults to GetSetSoftSeek() when no explicit param

2. SET DELETED ON + INDEX: SkipIndexed skips deleted records
   - GoTopIndexed: skip deleted record at top position
   - SkipIndexed: inner loop continues past deleted records

3. Compound key (CITY+NAME): field name TrimSpace before lookup
   - evalKeyExprInner: TrimSpace on fieldName after FIELD-> strip
   - Fixed "CITY " != "CITY" mismatch from + operator splitting

4. SET INDEX TO filename: treated as string, not variable
   - gengo uses exprToString for SET INDEX TO (was emitExpr)
   - Prevents identifier being resolved as local variable

5. hasXBaseCommands: recursive scan into nested blocks
   - BEGIN SEQUENCE, IF, FOR, DO WHILE, SWITCH bodies now scanned
   - Fixes missing hbrdd import for DB commands inside blocks

Thorough test: 77 items (14 sections) covering exact/partial/soft seek,
SET DELETED, duplicate keys, numeric keys, compound keys, empty/single
table, state consistency, order switching, full traversal — all identical.

21fd9dc65c 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)
