Five v0.9 — Harbour + Go fusion language

- Compiler: PP → Lexer → Parser → Analyzer → Gengo pipeline
- Parser: 232/236 (98%) Harbour compatibility, registry-based dispatch
- RTL: 351 Harbour-compatible functions
- RDD: DBF/NTX/CDX engines with Rushmore bitmap optimization
- Go Interop: IMPORT + pkg.Func() + obj:Method() with FastPath (15M calls/sec)
- HB_FUNC API: Full Harbour C API compatible Go bridge
- Concurrency: SPAWN/LAUNCH/GOROUTINE, <-, WATCH, PARALLEL FOR, ASYNC/AWAIT
- Extensions: Multi-return, DEFER, Slice, f-string, Nil-safe ?:, CONST
- Macro Compiler: Runtime AST parsing and evaluation
- Debugger: TUI debugger with source display, breakpoints, stepping
- FRB: Native + Pcode dual mode runtime binary
- Tests: 13 packages ALL PASS
