ChuckandClaude Opus 5.5 2601cb4cbb chore(deprecation): remove the 35 APIs deprecated for 3.8.0 (#708) 
* chore(deprecation): remove the 35 APIs deprecated for 3.8.0

The usage scan (docs/DEPRECATIONS_3.8.md, regenerated 2026-10-01 and
committed here) finds no call or override of any of them in the 46
monorepo plugins or the 8 third-party plugins plugins.json lists; the
only core callers were other deprecated methods removed alongside.

- CacheManager: 13 methods, plus the private helpers only
  has_data_changed used (_has_*_changed, _is_market_open).
- DisplayManager: 7 methods, plus WEATHER_COLORS and the private
  _draw_sun/_cloud/_rain/_snow/_storm helpers only the icon methods used.
- FontManager: 14 methods, plus size_tokens, _save_overrides and
  _clear_plugin_font_cache. font_overrides and _load_overrides stay:
  resolve_font() still applies config/font_overrides.json.
  performance_stats stays: get_font() keeps it and tests read it.
- PluginManager.get_enabled_plugins.

test_deprecation.py pins only the two 3.9.0 markers now; the scanner
tests run against a stand-in core instead of the real markers. The
memory-tier tests read stats through log_memory_cache_stats() and the
component, and the test of the removed _clear_plugin_font_cache goes.
Docs drop the removed methods' reference entries; the Deprecated APIs
table becomes "Removed in 3.8.0". CHANGELOG gains a Removed section.

* chore(deprecation): drop the test harness's copies of the removed icon methods

VisualTestDisplayManager still drew weather icons that DisplayManager no
longer has, so a plugin's visual tests could pass on calls that raise
AttributeError on the real display. Its draw_sun/draw_cloud/draw_rain/
draw_snow/draw_weather_icon/draw_text_with_icons, WEATHER_COLORS and the
private helpers go, with the tests that exercised them. The CHANGELOG's
Deprecations entries no longer say nothing is removed.

# Deprecated plugin APIs: usage scan
Generated by `scripts/plugin_api_usage.py` — do not edit by hand; re-run it (see [How to re-run](#how-to-re-run)).
- Scanned: 2026-10-01, core 3.7.0
- Monorepo: [ChuckBuilds/ledmatrix-plugins](https://github.com/ChuckBuilds/ledmatrix-plugins) (main @ 4de1d134), 46 plugins
- Third-party plugins: 8 with their own repo in `plugins.json` (f1-live, gif-player, pga-tour-leaderboard, plex-marquee, ledmatrix-dresden-departures, tidbyt-baseball-scoreboard, sleeper-fantasy, ledmatrix-nascar)
**37 deprecated methods: 36 unused, 1 still used, 0 need review.**
Counted per plugin: a *call* is `<receiver>.method` on an object named like the owner (`cache_manager`, `display_manager`, `font_manager`, `plugin_manager`), or on `self`/`super()` in a subclass; an *override* is `def method` in a subclass of the owner. *Review* hits are `.method` on a receiver whose type the scan cannot tell. *Internal* hits sit inside another deprecated core method and go with it. *Unrelated* hits are a different class's own method with the same name (a name collision), and never block removal; neither do hits in test files.

## How to re-run
```bash
# Clones the monorepo and each third-party plugin (depth 1) into a temp cache:
python3 scripts/plugin_api_usage.py --output docs/DEPRECATIONS_3.8.md
# Or scan a local monorepo checkout (read only) instead of cloning it:
python3 scripts/plugin_api_usage.py --monorepo ../ledmatrix-plugins
```
Before removing a method in its release, re-run the scan against the current monorepo and registry: a plugin added since this file was generated may have started calling it. Remove only methods the fresh scan reports unused; move the rest to a later release (the test in `test/test_deprecation.py` fails while a marker names a release at or below `src.__version__`).
