James Rich e6b08fff65 fix: Address P3 + P4 code-review findings — pre-existing bugs + perf regressions
P3 — Pre-existing bugs surfaced when files were moved:

- MeshUser.hwModelString: the unconditional replace('p', '.') mangles any
  hardware enum name containing a literal 'p' (HELTEC_WIRELESS_PAPER had
  become 'heltec-wireless-.a.er'). Use a regex bounded by digits so version
  markers like RAK4631_V1P0 → rak4631-v1.0 still work and other 'p's are
  preserved.
- EnvironmentMetrics.relativeHumidity: document the special-case
  `it != 0.0f` filter. It's intentional — firmware reports 0%RH when the
  humidity sensor isn't fitted and a real outdoor 0%RH reading is
  physically implausible. Other fields don't get this guard because their
  zero values (0V, 0A, 0°C) are meaningful sensor data.

P4 — Performance regressions introduced by the AIDL refactor:

- NodeManagerImpl: restore the O(1) byId index. The refactor dropped the
  secondary nodeDBbyID map and made getNodeById a linear scan over the
  whole node DB. getNodeById is called per-incoming-packet from
  MeshDataHandlerImpl (three times — shouldFilterMessage,
  handleNotificationMessage, getSenderName) and per-outbound send from
  CommandSenderImpl.resolveNodeNum.ById. The new NodeIndex holder maintains
  byNum and byId together in a single atomic ref so concurrent readers
  never see an inconsistent snapshot.
- NodeWithRelations.toModel: inline directly to a single Node(...)
  constructor call. The previous form did `node.toModel().copy(metadata=…,
  manuallyVerified=…)` which allocated the Node twice per DB row — wasteful
  on every nodeDBbyNum emission.
- NodeRepositoryImpl.getUser: replace two NodeAddress.fromString(userId)
  calls with a single string equality check against NodeAddress.ID_LOCAL.
  getUser is on the hot path for paged contacts and message arrival.

:core:data

Overview

The :core:data module implements the Repository pattern, serving as the primary data source for ViewModels in feature modules. It orchestrates data flow between the local database (core:database), remote services, and network repositories.

Key Components

1. Repositories

  • NodeRepository: High-level access to node information and mesh state.
  • MeshLogRepository: Access to historical logs and diagnostics.
  • FirmwareReleaseRepository: Manages the discovery and retrieval of firmware updates.

2. Data Sources

Internal components that handle raw data fetching from APIs or disk.
