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.
