March Madness is now available in the ledmatrix-plugins monorepo store
(ChuckBuilds/ledmatrix-plugins/plugins/march-madness) and should be
installed via the Plugin Store like any other plugin.
Removing the bundled copy so new installs don't automatically include it.
Existing users keep their installed version until they choose to uninstall.

Without |int, a string-typed value (e.g. from a hand-edited config.json)
causes both selected tests to fail and the select renders with no option
pre-selected. Matches the existing pattern used for multiplexing.

The upstream library defaults gpio_slowdown to 1 for Pi 5 (IsPi4() ? 2 : 1).
In PIO mode the value is a pixel-clock divisor, so 4-5 was unnecessarily
conservative advice. Updated help text and error log to reflect the actual
range (1-3 typical for Pi 5 PIO; inverted effect in RIO mode).

- Add rp1_rio select (PIO/RIO) to Display Settings hardware config section;
saved via /api/v3/config/main with 0-or-1 validation — previously the key
existed in config.json but was not editable from the UI
- Update gpio_slowdown help text with per-model guidance (Pi 3: 3, Pi 4: 4,
Pi 5: 4–5) and raise max from 5 → 10 to match full library range
- Fix gpio_slowdown Python fallback default from 2 → 3 (only affects edge case
where the runtime config section is absent; explicit config values are unchanged)
- display_manager writes /tmp/led_matrix_hw_status.json at startup: ok/error;
Display Settings page fetches it and shows a yellow warning banner when the
matrix failed to initialize, including Pi 5 remediation steps
- Add GET /api/v3/hardware/status endpoint that reads the status file
- Improve fallback error log to include Pi 5 rebuild hint
Pi 3/4 users: rp1_rio=0 is set in config but silently ignored by the library
on non-RP1 hardware; all other changes are additive or tighten defaults only.
