T07: Integracija — Supervisor struct sa end-to-end tokom

- Supervisor struct: NewSupervisor, Run, RunNext, execute
- E2E tok: scan → find → active → run → verify → report → review
- cmdRun u CLI koristi Supervisor
- 8 e2e testova sa mock agentom, 67 ukupno — svi prolaze
- T06 premešten u done/

+## Šta je urađeno
+
+Implementiran Supervisor struct sa end-to-end tokom u `code/internal/supervisor/`:
+
+### Izmenjeni/kreirani fajlovi
+
+| Fajl | Opis |
+|------|------|
+| `supervisor.go` | Supervisor struct, NewSupervisor, Run, RunNext, execute |
+| `supervisor_test.go` | 8 end-to-end testova sa mock agentom |
+| `cmd/kaos-supervisor/main.go` | cmdRun koristi Supervisor umesto ručnog toka |
+
+### Supervisor API
+
+- **NewSupervisor(cfg)** — kreira supervisor iz konfiguracije
+- **Run(taskID)** — pokreće task po ID-u: scan → find → active → run → verify → report → review
+- **RunNext()** — nalazi sledeći spreman task i pokreće ga
+- **execute(task)** — interni pipeline
+
+### Testovi — 8/8 PASS (supervisor e2e)
+
+```
+TestSupervisor_Run_EndToEnd              PASS (0.53s)
+TestSupervisor_RunNext_PicksCorrectTask  PASS (0.53s)
+TestSupervisor_RunNext_BlockedTask       PASS
+TestSupervisor_RunNext_NoTasks           PASS
+TestSupervisor_Run_TaskNotFound          PASS
+TestSupervisor_Run_TaskNotReady          PASS
+TestSupervisor_Run_FailedVerification    PASS (0.04s)
+TestNewSupervisor                        PASS
+```
+
+### Ukupno projekat: 67 testova, svi prolaze
+
+| Paket | Testova |
+|-------|---------|
+| cmd/kaos-supervisor | 8 |
+| internal/config | 7 |
+| internal/supervisor | 52 |
+| **Ukupno** | **67** |
+
+- `go vet ./...` — čist
+- `go build ./...` — prolazi

+## Opis
+
+End-to-end tok: CLI pozove run → učita task → pokrene agenta →
+verifikuje → napiše izveštaj → premesti task. Sve komponente
+povezane u jedan flow.
+
+## Fajlovi za izmenu
+
+```
+code/internal/supervisor/
+├── supervisor.go      ← Supervisor struct, Run() metoda
+└── supervisor_test.go ← end-to-end testovi
+```
+
+## Supervisor struct
+
+```go
+type Supervisor struct {
+    Config     *config.Config
+    TasksDir   string
+    CodeDir    string
+    ReportsDir string
+}
+
+func NewSupervisor(cfg *config.Config) *Supervisor
+func (s *Supervisor) Run(taskID string) error
+func (s *Supervisor) RunNext() error
+```
+
+## Run() tok
+
+```go
+func (s *Supervisor) Run(taskID string) error {
+    // 1. ScanTasks(s.TasksDir)
+    // 2. FindTask(taskID) — proveri da je u ready/
+    // 3. MoveTask → active/
+    // 4. RunTask(task, s.CodeDir, s.Config.Timeout)
+    // 5. Verify(s.CodeDir)
+    // 6. WriteReport(task, runResult, verifyResult, s.ReportsDir)
+    // 7. Ako AllPassed → MoveTask → review/
+    // 8. Ako !AllPassed → MoveTask → review/ (sa statusom failed u izveštaju)
+    // 9. Prikaži rezime
+}
+```
+
+## RunNext() tok
+
+```go
+func (s *Supervisor) RunNext() error {
+    // 1. ScanTasks
+    // 2. NextTask — prvi iz ready/ sa ispunjenim zavisnostima
+    // 3. Ako nema → vrati poruku "nema taskova"
+    // 4. Run(task.ID)
+}
+```
+
+## Integracija sa CLI
+
+main.go poziva:
+- `run T01` → supervisor.Run("T01")
+- `run` (bez ID) → supervisor.RunNext()
+- `status` → ScanTasks + ispis
+- `next` → NextTask + ispis
+- `verify` → Verify + ispis
+- `history` → čitaj reports/ + ispis
+
+## Testovi
+
+- End-to-end: napravi temp TASKS/ strukturu, stavi task u ready/,
+  pokreni Run() sa mock komandom → proveri da je task u review/,
+  izveštaj napisan, output tačan
+- RunNext: dva taska u ready/, jedan sa neispunjenom zavisnošću →
+  pokrene pravi
+- Nema taskova u ready/ → graceful poruka
+- Task koji je već active/ → greška
+- Failed verifikacija → task u review/ sa failed statusom u izveštaju
+- Config greška → graceful poruka
+
+## Očekivani izlaz
+
+`kaos-supervisor run T01` prolazi ceo tok od učitavanja do izveštaja
+(sa mock agentom). `go test ./... -v` — svi testovi zeleni.
