release: bump version to 0.1.9.5

Drei Stefan-Bugs aus dem ersten Deploy-Test plus die fehlenden Polish-
Features fuer die Projekt-Funktion.

Fixes:
- ProjectsBrowser-Spinner-Hang: useRef-Pattern statt useCallback([onActive
  Changed]) — Parent uebergibt inline-arrow-Callbacks, neue Identitaet
  jedes Render → useCallback recomputes → useEffect refeuert → infinite
  Spinner. Fix: Ref-Bridge fuer Callbacks, useCallback mit empty deps.
- ChatScreen Banner: zusaetzlicher × Hauptchat-Button rechts (sichtbar
  nur wenn Projekt aktiv) — ein Tap und zurueck zum Hauptthread, ohne
  Modal-Umweg.

Features:
- Brain ChatOut.project_id: aktive Projekt-ID NACH dem Turn (kann
  durch project_enter/exit-Tools waehrend Turn gewechselt sein). Bridge
  liest sie aus dem /chat-Response und haengt sie an jeden ARIA-Chat-
  Broadcast als payload.projectId.
- App: ChatMessage.projectId-Feld. User-Bubbles werden mit aktiver
  Projekt-ID getaggt vor dem Senden (auch im RVS-Payload). ARIA-Bubbles
  kriegen die ID vom Bridge.
- App: Chat-Verlauf rendert aufeinanderfolgende Project-Messages als
  einklappbaren Block mit Header (▶/▼ + Projekt-Name + Count). Auto-
  Collapse beim Projekt-Wechsel (altes ein, neues aus), Default beim
  ersten Render: alle inaktiven Projekte eingeklappt.
- File-Manager Project-Tagging:
  - diagnostic/server.js: Manifest /shared/config/file_projects.json
    + /api/files-list returnt projectId pro Datei + neuer Endpoint
    /api/files-set-project.
  - bridge/aria_bridge.py: nach App-Upload Auto-Tag mit aktivem Projekt
    (Brain-Status-Query, best-effort fail-silent).
  - App SettingsScreen: scrollbare Projekt-Pill-Reihe als Filter, default
    auf aktives Projekt wenn vorhanden, sonst "Alle Projekte".
  - Diagnostic: zweites Dropdown im Files-Tab, baut Projekt-Optionen
    dynamisch aus /api/brain/projects/list.

Bewusst nicht drin (Folgeschritt):
- Per-File "Projekt zuweisen"-Action (Long-Press / Right-Click)
- Filter-Sync zwischen ChatScreen-Banner und SettingsScreen-Filter
