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

perf: fused opcodes + inline EOF/BOF/Found/RecNo/Deleted
...
Fused opcodes (ops_compare.go):
- LocalLessEqualInt: FOR i<=N without Push+LessEqual+PopLogical
- LocalGreaterEqualInt: FOR STEP -1
- Direct local access + int comparison (no stack, no Value boxing)
gengo FOR loop:
- Detects literal TO value → emits LocalLessEqualInt (3 calls → 1)
- Falls back to stack-based for variable limits
Inline RDD functions (gengo tryEmitInlineRTL):
- EOF/BOF/Found/Deleted/RecNo/RecCount: direct area method call
- No FindSymbol + PushNil + Do(0) + Frame/EndProc overhead
- Uses hoisted _darea when inside DO WHILE context
Results (50K, ext4):
SEEK random: 63ms (Harbour 67ms — FASTER!)
SEEK seq: 44ms (Harbour 27ms — 1.6x)
CDX SEEK NAME: 47ms (Harbour 27ms — 1.7x)
CDX SEEK ID: 24ms (Harbour 17ms — 1.4x)
All counts correct. 82/82 stress PASS. 14 packages ALL PASS.

perf: VM hot-path optimization — cached values + inline stack ops
...
value.go:
- cachedNil, cachedTrue, cachedFalse: pre-built constant Values
- MakeBool()/MakeNil(): return cached (zero allocation)
- smallInts[256]: pre-built integers 0-255 (skip intExpLen loop)
- MakeInt(): fast path for 0-255
thread.go:
- pop(): use cachedNil for GC help (no MakeNil() call)
ops_compare.go:
- LessEqual(): inline Int-Int fast path (skip valueCompare)
Direct scalar comparison with cached bool result
- Not(): inline logical fast path (skip IsLogical+AsBool)
- PopLogical(): inline type check + scalar read
Impact: these functions called millions of times in FOR/DO WHILE loops.
10K SEEK: 20ms → 16ms (20%). CDX SCOPE: 12ms → 9ms (25%).
82/82 stress PASS. 14 packages ALL PASS.
