486e466592 feat: FiveSql2 43/43, @byref, mutable closure, RTL 479, DateTime fix 
Major changes since last commit:
- FiveSql2 SQL:1999 engine (10,458 LOC) — 43/43 ALL PASS
- 21 compiler/runtime bugs fixed (short-circuit AND/OR, FOR LOOP, etc.)
- @byref pass-by-reference via RefCell pattern
- Mutable closure capture (EnsureLocalRef + RefCell sharing)
- RTL: 400 → 479 functions (+79: file, string, datetime, hash, UTF-8)
- DateTime/Timestamp fully working (hb_DateTime, hb_Hour/Min/Sec, display)
- Reserved word guard (39 keywords blocked from function calls)
- AEval arg order fix (element before index)
- Closure capture redecl fix (unique _cap_ names per block)
- Hash/string indexing in ArrayPush/ArrayPop
- Harbour compat test suite: 51/51
- 4 docs: Porting Report, Implementation Plan, Optimization Plan, Commercialization

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)

542373572f feat: MemRDD — in-memory database engine (Go map-based) 
Complete in-memory RDD implementation:
- CRUD: Create, Append, GetValue, PutValue, Delete, Recall
- Navigation: GoTo, GoTop, GoBottom, Skip, BOF, EOF
- Index: CreateIndex (sorted slice + binary search), Seek (exact + soft)
- Bulk: Pack (remove deleted), Zap (clear all)
- Multi-open: shared table across work areas
- Driver registered as "MEMRDD", prefix "mem:"

Tests: 9 tests including 5000-record stress test
  Create, Append/Get/Put, Navigation, Delete/Pack, Zap,
  Index (string + numeric), Seek (exact + soft), Stress 5000, Multi-open

Use cases: temp tables, query results, pivot, caching
Performance: no disk I/O, no byte packing — pure Go slices
