fix: Code review round 2 — race conditions, dead code, hardcoded paths

Browse Source 
CRITICAL fixes:
- #1 vm.go: Mutex on libModules/dynamicFuncs global slices
  RegisterLibModule/RegisterDynamicFunc now thread-safe
  RegisterLibModules copies under lock, clears, releases
- #4 shutdown.go: Signal handler goroutine leak fixed
  Uses done channel + select for clean exit on normal shutdown

HIGH fixes:
- #7-8 gobridge.go: Remove dead if/else branches (both identical)
- #13-14 main.go: Remove hardcoded /mnt/d/harbour-core paths
  Use HB_INC env var + standard /usr/local/include/harbour only
- #15 main.go: Remove unused frbModSeq variable

MEDIUM fixes:
- #22 expr.go: Remove unused parts variable in parseInterpolatedString
- #51 macro.go: Remove var _ = fmt.Sprintf import guard
- macroeval.go: Remove unused lexer import and guard

Total fixed this session: 12/53 issues resolved
Remaining: 41 (CRITICAL: 1, HIGH: 9, MEDIUM: 16, LOW: 16)
