e95afad4ee feat: Harbour RDD parity — NTX/CDX 100% compatible, FIELD-> works 
Five RDD engine now matches Harbour DBFNTX and DBFCDX byte-for-byte
in ordering, seek, navigation, and field access. Verified against
Harbour 3.2.0dev with a 281-line comparison test covering:
  - Natural/NAME/CITY/AGE/SALARY/UPPER ordering
  - SEEK (exact/not-found), GoTop/GoBottom per order
  - DELETE/RECALL with SET DELETED
  - CDX compound index read with 5 tags (BYNAME, BYCITY, BYAGE, BYSAL, BYUNAME)
  - Reverse traversal

Fixes:

1. FIELD->NAME returned NIL
   GetAliasField returned interface{} but runtime expected hbrt.Value,
   so the type assertion in PushAliasField failed and pushed NIL.
   - workarea.go: change return type to hbrt.Value, handle FIELD/_FIELD
     as current-workarea alias, add SetAliasField
   - gengo.go: emit SetAliasField() for alias->field := value in both
     statement and expression contexts

2. OrdSetFocus(n) silently switched to natural order
   v.AsString() returns "" for a numeric Value, so OrderListFocus("")
   set current=-1.
   - indexrtl.go: convert numeric param via fmt.Sprintf("%d", ...)

3. CDX compound tag order mismatched Harbour
   Five decoded the structural B-tree which is alphabetical, but
   Harbour sorts tags by TagBlock (file offset = creation order).
   - cdx/cdx.go: sort tagEntries by offset ascending after decoding,
     matching hb_cdxIndexLoadAvailTags in dbfcdx1.c

4. OutStd()/OutErr() not registered — caused panic on call
   - hbrtl/console.go: add rtlOutStd/rtlOutErr implementations
   - hbrtl/register.go: register OUTSTD and OUTERR
   - analyzer.go: add OUTSTD/OUTERR to RTL known-functions

5. FIELD keyword triggered "undeclared variable" warnings
   - analyzer.go: add FIELD, _FIELD, M, MEMVAR as builtin constants

Tests:
  go test ./...        — ALL PASS (17 packages)
  FiveSql2 43/43       — 100%
  compat_harbour 51/51 — 100%
  Harbour diff         — 0 lines differ (281-line comparison)

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
