docs(events): reorganize presentation and launcher documentation

Split the monolithic MODULE__AE_Events_PressMgmt_Launcher.md into focused,
granular modules to improve maintainability and onsite utility.

- Created MODULE__AE_Events_Presentation_Management.md (Back-office focus)
- Created MODULE__AE_Events_Launcher.md (Podium display focus)
- Created GUIDE__AE_Events_Onsite_Runbook.md (SRR and onsite workflows)
- Promoted PROJECT__AE_Events_Launcher_Native_integration.md to
  MODULE__AE_Events_Launcher_Native.md (Permanent technical reference)
- Renamed 'Press Mgmt' references to 'Presentation Management' for clarity.
- Removed redundant README.md in launcher route.

+# Guide — Aether Events: Onsite Runbook
+
+This guide covers the human-centric logistics and "In the Heat of the Moment" support for onsite event operations using Presentation Management and the Launcher.
+
+---
+
+## Speaker Ready Room (SRR)
+
+The SRR is the central hub for content management and presenter support.
+
+### SRR Practice Stations
+Stations mirror the session room setup exactly:
+- Same Mac laptop model and adapter/dongle configuration as the podiums.
+- Projector and screen (where possible).
+- Launcher running in **Native** mode — ensures verification matches the podium experience.
+
+### Staffing Roles
+
+| Role | Access Level | Typical Tasks |
+|---|---|---|
+| **OSIT Staff** | `trusted_access` | Manage devices, monitor via VNC, deep troubleshooting. |
+| **Client Staff** | `authenticated_access` | Upload files, view session lists, assist presenters. |
+| **Presenter** | `authenticated_access` | Self-upload via QR link (if enabled). |
+
+### SRR Workflow — Day-of-Show
+1. **Check-in:** Staff looks up the presenter's session in Presentation Management.
+2. **Upload:** File is uploaded to the presenter/session record.
+3. **Verification:** Staff opens the file on a practice station to confirm rendering.
+4. **Launcher Sync:** File propagates to the podium. Use **Force Sync Location** in the Launcher config if immediate full-room caching is needed.
+5. **Proceed:** Presenter walks to the room; the podium kiosk already has the file cached.
+

+
+## Onsite Operation (Managing Parallel Rooms)
+
+### SRR Overview Page
+The Pres Mgmt overview (`/events/[id]/pres_mgmt`) is the "Command Center":
+- Monitor file status per session.
+- Filter by location and time block to stay ahead of active sessions.
+
+### Per-Room Monitoring
+- Use **VNC or RustDesk** to monitor all podium screens in real time from the SRR.
+- Confirm "Native Sync" status chip in the bottom-left of the Launcher is green/idle before sessions start.
+
+### Session Transitions
+- **Timing:** Ideally, sessions show/hide based on `datetime_start`.
+- **Manual Control:** In looser schedules, use Launcher controls to manually select the current session.
+
+---
+
+## Pre-Show Checklist
+
+### 1–2 Weeks Before
+- [ ] Event created with correct dates and timezone.
+- [ ] `mod_pres_mgmt_json` configured for client needs.
+- [ ] Locations (rooms) created and named.
+- [ ] Sessions created, assigned to locations, and timed.
+- [ ] Launcher devices (`event_device`) registered with correct codes.
+- [ ] Device-to-location assignments confirmed.
+
+### Day Before (SRR Setup)
+- [ ] Mac laptops at podiums booted; Electron app running.
+- [ ] Each podium confirms it loaded the correct room's Launcher.
+- [ ] SRR practice stations confirmed (matching hardware).
+- [ ] Run **Force Sync Location** on all podiums to pre-cache all day-1 content.
+- [ ] VNC/RustDesk connections established to all podiums.
+
+### Day of Show
+- [ ] Confirm all session times are accurate before the first block.
+- [ ] Monitor SRR queue and verify every file on a practice station.
+- [ ] Check VNC wall to ensure all podiums are online and synced.

+
+## Troubleshooting
+
+| Symptom | Cause | Fix |
+|---|---|---|
+| Session not in Launcher | Datetime wrong or Location unassigned. | Verify session metadata in Pres Mgmt. |
+| File uploaded but missing | Polling lag or attached at wrong level. | Wait 30s; check if file is at Session vs Presenter level. |
+| File opens slowly | Not in native cache yet. | Check "Native Sync" chip; use Force Sync in config. |
+| File won't open | Corrupt upload or missing Mac codec. | Test on SRR station; convert or re-upload. |
+| Drifted schedule | Room timing shifted. | Use Launcher controls to manually select the active session. |
+| `lock_config` resets changes | Remote config is forced. | Edit the master `mod_pres_mgmt_json` in Event Settings. |
+| Move laptop to new room | Hardware reassignment. | Update `location_id` in `event_device` record; restart Electron. |
