fix(reticulum): stop blocking LoRa BLE while healthy RNode is online

[rinchen]

Summary

• Exclusive LoRa GATT dispose (releaseGattBleCentral) is only for bleBondRemoved / LTK desync recovery — not while a healthy BLE RNode is online.
• fix(reticulum): recover macOS BLE RNode LTK desync without false Paired state #1034’s permanent RNode-online hold blocked MeshCore BLE whenever Reticulum’s RNode came up (Meshtastic still worked over TCP).
• Source-contract test asserts the online-RNode exclusive path cannot return.

Test plan

• useReticulumRuntime.reconnect-hardening.test.ts (pre-commit / local)
• Quit app, restart with Reticulum BLE RNode + MeshCore BLE auto-connect
• Confirm MeshCore connects after RNode is online (no rnode_bond_recovery error)
• Confirm Meshtastic still connects (TCP or BLE)
• Optional: trigger real bond/LTK recovery and confirm exclusive hold still engages only then

Summary by CodeRabbit

• Bug Fixes
  • LoRa GATT access is no longer blocked while a healthy BLE RNode is online.
  • Exclusive access is now limited to Bluetooth bond recovery and LTK desynchronization scenarios.
  • BLE coexistence between MeshCore/Meshtastic and LoRa connections is preserved.

📝 Walkthrough

Walkthrough

The runtime no longer disposes or exclusively holds LoRa GATT when a healthy BLE RNode is online. Exclusive disposal remains limited to bond-recovery handling. Documentation and regression assertions reflect this behavior.

Changes

RNode bond recovery handling

Layer / File(s)	Summary
Remove healthy RNode LoRa GATT hold src/renderer/runtime/useReticulumRuntime.ts, src/main/gatt-sidecar-proxy.ts, src/renderer/runtime/useReticulumRuntime.reconnect-hardening.test.ts	The runtime removes online-RNode hold tracking and periodic release logic. Exclusive LoRa GATT disposal remains associated with bond recovery and LTK desynchronization. The documentation and regression assertions reflect the updated behavior.
