Replace the stub GeminiNanoSummaryProvider with a real implementation
that uses com.google.mlkit:genai-prompt:1.0.0-beta2 for on-device
AI-powered scan summaries on supported Android hardware.
Implementation:
- Generation.getClient() to obtain the GenerativeModel
- generateContentRequest with TextPart for structured prompts
- Temperature 0.3, topK 16, maxOutputTokens 200 for concise output
- Graceful fallback to DiscoverySummaryGenerator on any failure
- Lazy model initialization with error logging via Kermit
The existing buildSessionPrompt() and buildPresetPrompt() methods in
DiscoverySummaryGenerator provide the prompt text. On unsupported
devices or fdroid builds, the provider falls through to the
deterministic algorithmic summary seamlessly.

Replace all hardcoded strings in discovery UI screens and components
with stringResource() calls using centralized string resources.
Files updated:
- DiscoverySummaryScreen: session stats, AI analysis labels
- DiscoveryHistoryDetailScreen: history metadata labels
- DiscoveryScanScreen: disabled button semantics descriptions
- PresetPickerCard: selected/unselected state descriptions
- PresetResultCard: scan result stat labels
- RfHealthSection: RF health stat labels
- DwellProgressIndicator: dwell progress text
Added 33 new discovery_stat_* and discovery_* string resources.

- Fix resource leak: collectorRegistry.collector was never cleared in
the successful scan completion path (only in stop/abort paths)
- Replace hardcoded 'Local Mesh Discovery' strings in both Settings
screens with stringResource(Res.string.discovery_local_mesh)
- Add missing explicit imports for the CMP string accessor
- Remove redundant .gitkeep files from directories with content

- Add rankings StateFlow to DiscoverySummaryViewModel
- Compute rankings from PresetRankingInput on loadNodes and rerunAnalysis
- Pass rank/isTied to PresetResultCard for display
- Show rank badge (#1, #2, tied) in preset header
- Rank 1 (untied) highlighted in primary color
Validated: spotlessApply, allTests, compileKotlinJvm
Implement the spec's ranking and recommendation heuristic:
1. Highest unique discovered node count
2. Highest neighbor-report diversity (direct + mesh)
3. Highest non-duplicate packet count
4. Best median link quality (SNR first, then RSSI)
5. Greatest best known distance
6. Lowest failure/reconnect penalty
Presets tied after all 6 criteria share the same rank with isTied=true.
Includes RankingScoreBreakdown for transparent per-criterion scoring.
11 unit tests covering each criterion as tiebreaker, full ties,
edge cases (empty/single preset, no nodes, failed presets).
Validated: spotlessApply, allTests, kmpSmokeCompile
- Add Preparing, Cancelling, Failed states to DiscoveryScanState (FR-008)
- Change Complete to data class with CompletionOutcome enum
- Add local-mesh-discovery deep link routes to DeepLinkRouter (FR-031)
- Compute packetSuccessRate/packetFailureRate in scan engine (FR-012)
- Fix DiscoveryScanEngineTest compilation and restructure with shared scheduler
- All 8 tests pass, kmpSmokeCompile clean
- Replace platform-specific `String.format` with Kotlin standard library `padStart` in `DwellProgressIndicator` to support common code.
- Simplify fully qualified icon references in `DiscoveryGoogleMap` by adding explicit imports.
- Implement distance tracking using `latLongToMeter` and a new `getMaxDistance` DAO query
- Calculate Airtime Rate as a delta over time to align with telemetry specifications
- Capture and restore the full `LoRaConfig` instead of just the modem preset after a scan
- Persist local radio statistics (Tx/Rx counts, uptime, relay stats) in preset results
- Backfill missing node names and positions from the local NodeDB during discovery
- Refactor `DiscoveryScanEngine` to use injected `CoroutineDispatchers` and `ApplicationCoroutineScope`
- Reduce BLE connection priority request delay in `BleRadioTransport` to 1 second
- Improve test reliability by replacing fixed `Thread.sleep` calls with state-based polling and `delay`
* Introduce a new `:feature:discovery` module for scanning mesh topology across multiple LoRa presets

* Update database schema to version 39 with tables for discovery sessions, preset results, and discovered nodes
* Implement UI screens for scan configuration, real-time progress, and historical session management
* Add flavor-specific discovery maps (Google Maps and OSM) for visualizing node positions and topology
* Include algorithmic and AI-powered summary generation for analyzing LoRa preset performance
* Add report export functionality for Text and PDF formats
* Integrate discovery entry point into the settings screen and navigation graphs
