feat(telemetry): add per-app metrics and log telemetry to hub reports (v0.28.0)

Browse Source 
- New internal/metrics/telemetry.go: MetricsStore.GetContainerTelemetry()
  aggregates container memory/CPU from SQLite over the last 15 min
- New internal/metrics/logscanner.go: ScanContainerLogs() scans docker logs
  for errors/warnings, deduplicates via fingerprinting (strips timestamps,
  replaces 6+ digit numbers, hex strings, UUIDs)
- New internal/report/telemetry.go: buildAppTelemetrySection() assembles
  per-stack AppTelemetry by aggregating container metrics and log summaries
- internal/report/types.go: added AppTelemetry field to Report struct plus
  AppTelemetry type with memory/CPU/log fields and LogIssue references
- internal/report/builder.go: calls buildAppTelemetrySection() in BuildReport()
- Backward-compatible: old Hub versions silently ignore app_telemetry field

## Changelog
### v0.28.0 — App Telemetry & Analytics (2026-02-23)
#### Added
- **App telemetry in Hub reports** — `Report.AppTelemetry` (new field in `report/types.go`) carries per-stack memory/CPU metrics and log scan results to the Hub on every report push. Backward-compatible: old Hub versions silently ignore the new field.
- **`internal/metrics/telemetry.go`** — New `MetricsStore.GetContainerTelemetry(since)` method aggregates container memory (current/avg/peak) and CPU averages from the existing `container_metrics` SQLite table over the last 15 minutes.
- **`internal/metrics/logscanner.go`** — New `ScanContainerLogs(containerNames, since, logger)` function runs `docker logs --since=15m --tail=1000` on each non-protected deployed container. Detects errors/warnings by keyword matching, deduplicates via fingerprinting (strips timestamps, replaces 6+ digit numbers with `<N>`, hex with `<HEX>`, UUIDs with `<UUID>`). Returns `[]ContainerLogSummary` with counts and `RecentIssues` (top 10 per container).
- **`internal/report/telemetry.go`** — New `buildAppTelemetrySection()` and `buildAppTelemetry()` functions assemble per-stack `AppTelemetry` records by aggregating container-level metrics and log summaries. Only non-protected, deployed stacks are included.
#### Changed
- **`internal/report/builder.go`** — `BuildReport()` now calls `buildAppTelemetrySection()` after the stacks section, populating `r.AppTelemetry`.
- **`internal/report/types.go`** — Added `AppTelemetry []AppTelemetry` field to `Report` struct. Added new `AppTelemetry` type with fields: app_name, display_name, containers, memory metrics, catalog estimate/limit, log error/warning counts, and top issues.
### v0.27.3 — Real System Memory Everywhere (2026-02-23)
