Add LiveStash for state recovery across reconnects 
- Installed live_stash ~> 0.1 with browser memory adapter
- Map page: recovers selected_band and selected_time on reconnect
- Submit page: recovers active_tab (single/csv) on reconnect
- JS params initialized with initLiveStash wrapper

Remove timex, earmark, dns_cluster deps; add local implementations 
- Replace Timex with regex-based timestamp parser (broader format support)
- Replace Earmark with local Markdown.to_html! (headings, code blocks,
  tables, lists, inline formatting, links, horizontal rules)
- Remove dns_cluster (unused, single-instance deployment)
- Add stream_data property tests for timestamp parsing (5 properties
  covering ISO, US dates, AM/PM, format roundtrips, garbage rejection)
- Removes transitive deps: combine, tzdata, hackney, certifi, metrics,
  mimerl, parse_trans, ssl_verify_fun

Use Timex for flexible CSV timestamp parsing with tests 
- Add timex ~> 3.7, downgrade gettext to ~> 0.26 for compatibility
- Parse ISO 8601, US dates (M/D/YYYY), AM/PM, 24h, compact formats
- 22 tests covering all accepted timestamp formats and edge cases
- Integration tests for CSV import with US date and space-separated formats

Move ML deps to dev/test only, exclude from production build 
- Nx, Axon, EXLA, Polaris deps restricted to only: [:dev, :test]
- model.ex and training mix tasks moved to lib_ml/ (compiled via
  elixirc_paths in dev/test only)
- load_ml_model uses Code.ensure_loaded? + apply/3 to avoid
  compile-time references to ML modules in production
- Verified: MIX_ENV=prod compiles clean with no ML warnings

Add ML training pipeline with Polaris optimizer 
- Add polaris dep for Adam optimizer (Axon.Optimizers deprecated)
- Fix Model.train/3 to use Polaris.Optimizers.adam
- Training task: mix propagation_train with stratified band sampling
- Model encodes solar time (longitude/15) not fixed timezone

Add Nx/Axon/EXLA ML model skeleton for propagation prediction 
13-feature feed-forward network (atmospheric + temporal + frequency).
Includes build, init, predict, encode_features, save/load to disk.
Model weights saved to priv/models/propagation_v1.nx (gitignored).
Not yet trained — scaffolding only.

- Radio context with QSO schema and CSV import script (58K contacts)
- Solar index schema, GFZ client, and daily Oban cron worker
- LiveView dashboard with QSO table and weather correlation views
- Parallelize weather import script using Task.async_stream (10 concurrent workers)
- Replace sequential rate_limit sleeps with concurrency-based backpressure
- Atomic progress counter for interleave-safe reporting
