7e2a159b88 feat: CDX support + ORDSCOPE + cross-read Harbour compatibility 
CDX Integration:
- IndexEngine interface: common for NTX Index and CDX Tag
- OrderListAdd: auto-detects .cdx/.ntx extension, opens CDX tags
- decodeCompoundLeaf: proper bit-packed tag directory decoding
  (was stub falling through to scanCompoundLeaves with wrong names)
- CDX Tag: added KeyLen(), KeyExpr(), ForExpr(), IsDescending(), Close()
- CDX compound recNo = direct byte offset (not page number)

ORDSCOPE:
- SetScope/ClearScope/SetScopeTop/SetScopeBottom on DBFArea
- GoTopIndexed: seeks to scopeTop, validates within scopeBottom
- GoBottomIndexed: seeks to scopeBottom boundary
- SkipIndexed: stops at scope boundaries (top and bottom)
- OrdScope RTL function registered (nScope: 0=TOP, 1=BOTTOM)
- scopeKeyFromValue: converts Value to padded key bytes

Index Order Management:
- OrderListFocus: handles numeric order ("2" → order 2)
- SET ORDER TO n: gengo emits hbrt.NtoS for int-to-string conversion
- IndexOrd/OrdCount/OrdName/OrdKey: real implementations (were stubs)
- OrderCount/CurrentOrder/OrderName/OrderKeyExpr accessors on DBFArea
- ClearScope on order switch (prevents stale scope)

Cross-read test: Harbour-created CDX → Five reads, 20/20 items match:
  NAME/CITY/ID seek, ORDSCOPE count, GoTop/GoBottom all identical

6e78d12cc2 fix: 3 RDD compat bugs — FIELD->, AsNumInt Double, PACK/ZAP with index 
Bug 1: FIELD->NAME in INDEX ON expression
- evalKeyExprInner: strip FIELD->/alias-> prefix before field lookup
- exprToString: handle AliasExpr (FIELD->NAME → "FIELD->NAME")

Bug 2: AsNumInt() on Double returned IEEE 754 raw bits
- Value.AsNumInt(): check tDouble and convert via Float64frombits
- Fixed array index crash when index is result of % modulo

Bug 3: PACK/ZAP crash with open indexes
- OrderListRebuild: fully implemented (was TODO stub)
  Saves index info, closes all, sets idxState=nil, recreates
- OrderCreate: set current=-1 during key evaluation (natural GoTo)
- PACK/ZAP: save/restore idxState, rebuild after operation
- Register __DBPACK, __DBZAP, DBRECALL symbol aliases

Harbour vs Five: 45/47 match (96%), 2 diffs are duplicate-key sort order

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)

827adeeb99 feat: SET commands + ErrorBlock/Break error handling 
SET commands (setcmd.go):
  - SetDateFunc: __SetDateFormat([cNew]) → cOld
  - SetDecimalsFunc: SET DECIMALS TO n
  - SetEpochFunc: SET EPOCH TO n
  - 11 toggle functions: SetExact, SetDeleted, SetSoftSeek, SetExclusive,
    SetFixed, SetCancel, SetBell, SetConfirm, SetInsert, SetEscape, SetWrap
  - SET constants: _SET_EXACT, _SET_DELETED, etc. for PRG code
  - GetSetDateFormat(), GetSetDecimals(), GetSetEpoch() helpers
  - Default: DATE="mm/dd/yy", EPOCH=1900, DECIMALS=2

Error handling (error.go):
  - Break(xValue): panics with BreakValue, caught by BEGIN SEQUENCE
  - BreakBlock(): returns {|e| Break(e)} code block
  - LaunchError(): dispatches error through ErrorBlock handler
  - RuntimeError(): creates + launches standard runtime error
  - IsBreak(): checks if recovered panic is a BreakValue
  - createErrorHash(): builds Harbour-compatible error hash

Registration: ErrorBlock, ErrorNew, DosError, FError, Break + all SET functions

f950cb0784 fix: Phase 2 — HIGH #6,9,10,11,12,19,23,32,46,47 
Files modified (5):
  compiler/gengo/gengo.go — #6,#32: Deduplicate 3 Generate functions into 1
    doGenerate(file, debug, library) replaces 170 lines of copy-paste
    Dead GenerateDebug method removed
  cmd/five/main.go — #9,10,11,12: Fix 5 silently ignored errors
    filepath.Abs, tidy.Run, tidyCmd.CombinedOutput now checked
  hbrtl/strings.go — #19: Str() now reads caller's nWidth/nDec params
    Was ignoring explicit Str(123, 10, 2) arguments
  compiler/pp/pp.go — #46: Fix stale "NOT implemented" comment
    #47: Extract maxIncludeDepth constant
  compiler/lexer/lexer.go — #23: Remove unused LookupKeyword result

Issues resolved: 10 (HIGH: 7, MEDIUM: 3)
Total fixed: 26/53

7c61db70c3 fix: Critical code review fixes — race conditions, panic recovery, LTRIM/RTRIM 
CRITICAL fixes:
- fileio.go: Add sync.Mutex to file handle table (race condition #2)
  allocHandle/getHandle/removeHandle thread-safe helpers
- goroutine.go: Add defer/recover to GoLaunch/GoLaunchBlock
  Goroutine panic no longer crashes entire process (#5)

HIGH fixes:
- strings.go: Implement proper LTrim (TrimLeft) and RTrim (TrimRight)
  Previously both aliased to AllTrim — silent semantic bug (#18)
- register.go: TRIM = RTrim (Harbour compatible)

From 53-issue senior code review.
Remaining: 47 issues (HIGH: 10, MEDIUM: 18, LOW: 16, CRITICAL: 3)

272576f6ce feat: Harbour-compatible VM shutdown sequence 
Implements full cleanup on program exit (normal, Ctrl+C, crash):
- EXIT PROCEDURE auto-execution (reverse module order)
- AtExit callback registry (LIFO order)
- All WorkAreas auto-close (child before parent)
- Terminal restore (raw → normal) on signal/exit
- Static variables clear
- Signal handlers (SIGINT, SIGTERM) for clean shutdown
- shutdown.go: Harbour hb_vmQuit() 25-step sequence adapted for Five
- vm.go: Run() now calls Shutdown() via defer
- rawtty.go: terminal restore registered with shutdown system
