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)
