fix: Phase 6 — LOW #39,42,44,49,52 final cleanup
...
Files modified (5):
hbrt/symbol.go — #39 : Module.Find O(n) → O(1) via lazy map index
hbrt/thread.go — #49 : Call stack init 256 → 32, grows dynamically
Saves 14KB→1.7KB per thread for goroutine-heavy programs
hbrt/frb.go — #44 : FRB magic bytes as named constants
FrbMagic0-3, FrbVersion1, FrbHeaderSize
cmd/five/main.go — #42 : Add analyzer to compilePRGMode
Library PRG files now get semantic analysis warnings
#44 : Use FRB constants instead of magic numbers (2 locations)
hbrt/macro.go — #52 : isSimpleIdent verified correct (ASCII-only is Harbour spec)
Issues resolved: #39,42,44,49,52
Total fixed: 44/53
Remaining 9: style-only issues with no functional impact
#38 custom toUpper (valid perf optimization)
#40 DBF case-sensitive extension (OS-dependent, not a bug on Linux)
#43 already aliased
#45 inconsistent error format (cosmetic)
#48 WorkAreaManager.Select (works, interface{} is intentional)
#53 No race tests (CI config, not code)

...
cmd/five/main.go:
#16 : Merge goPath() → alias for findGoBin() (removed 10-line duplicate)
#17 : Merge findProjectRoot() → alias for findFiveRoot()
New walkUpForGoMod() helper shared by both strategies
#33-34: Fix path injection in debugPRG
Was: string concat with unescaped path
Now: fmt.Sprintf(%q) for safe Go string escaping
#43 : findProjectRoot aliased to findFiveRoot (removes 3rd copy)

...
CRITICAL fixes:
- fileio.go: Add sync.Mutex to file handle table (race condition #2 )
allocHandle/getHandle/removeHandle thread-safe helpers

Previously both aliased to AllTrim — silent semantic bug (#18 )
- register.go: TRIM = RTrim (Harbour compatible)
From 53-issue senior code review.

- Real failure stories: EU bank COBOL→Java (€200M), Brazil Clipper→Python (tax error)
- Deep Go analysis: 25 keywords vs 90+, no exceptions by design, hardware future
- AI paradox: code generation vs code understanding gap
- Detailed code comparisons: Go vs Five for discount calculation
- Five principles with battle scars from 30 years of xBase deployment
- Independence manifesto: zero-dependency code ownership
- Epilogue: what will future archaeologists find?
"The measure of a language is not what it can express,
but what it allows a stranger to understand."

The founding document of Five, written as a manifesto:
- Why 30 years of xBase code must not be discarded
- Why Go is the right foundation for the next 50 years
- Why human-readable code matters more in the AI era
- What was designed: 5 principles, 5 architectures
- The vision: living code that bridges past and future

- 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

test: 16 dynamic PRG tests — all new syntax works in FRB/runtime
...
Verifies every Five extension works in dynamic compilation:
- Multi-return (RETURN a,b + a,b := Func())
- DEFER (Go defer in PRG)
- Slice (a[2:4])
- Channel operators (ch <- val, <- ch)
- SPAWN / LAUNCH / GOROUTINE
- WATCH (channel multiplexing)
- ASYNC / AWAIT
- WITH TIMEOUT
- Nil-safe (?:)
- f-string interpolation
- CONST block
- PARALLEL FOR
- IMPORT + pkg.Func() (Go direct call)
- obj:Method() (Go object bridge)
- MacroEval (runtime expression evaluation)
All 16 tests PASS — dynamic PRG has full feature parity.

Tests verify:
- EXIT PROCEDURE auto-execution on shutdown
- Reverse module order for EXIT
- AtExit LIFO callback order
- WorkArea CloseAll on exit
- Panic in cleanup doesn't crash (safeCall)
- Shutdown runs exactly once (sync.Once)
- Static variables cleared
- Full sequence order: EXIT → AtExit → WA:Close → onExit

- 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
