v0.7.5 — WordPress.org slug rename: a-radio → rangerhq-radio

A third-party AI-driven naming check flagged `a-radio` as too
generic for the wp.org Plugin Directory (single common functional
word, no distinguishing prefix). The verdict was advisory but
defensible — short generic slugs are increasingly rejected as the
directory grows past 60K plugins. Fixing it preemptively is cheaper
than facing a rejection at submission time.

The new slug `rangerhq-radio` matches the public display name
"RangerHQ Radio" (unchanged) and lines up with the rest of the
RangerHQ plugin family: `rangerhq-spatial`, `rangerhq-glyph`,
now `rangerhq-radio`.

Changes (packaging only — no player behaviour change):
* Text Domain `a-radio` → `rangerhq-radio` across all 125 i18n
  call sites via in-place sed (esc_html__, _e, __, esc_attr_e
  and their friends). PHP lint clean post-rename.
* `Text Domain:` plugin header in radio.php line 15 → `rangerhq-radio`.
* `RADIO_GITEA_URL` constant value → new Gitea repo URL.
* README.md install link → new repo URL.
* readme.txt FAQ Gitea link → new repo URL.
* readme.txt Stable tag → 0.7.5.
* inc/about.php — v0.7.5 in "latest" slot; v0.7.4 demoted.

Unchanged deliberately (would have been pure churn):
* Plugin Name header "RangerHQ Radio" — already correct.
* Plugin URI.
* Internal constants `RADIO_*` — don't have to match slug.
* User-meta keys `radio_state` / `radio_history` /
  `radio_favourites` — renaming would orphan every existing
  user's settings on upgrade.
* HTML `data-radio-*` attributes — JS controller's element
  selectors in radio.js, not slug-related.
* CSS class names `radio-player`, `radio-about-*` — internal
  scoping.
* Main plugin file name `radio.php`.

Migration: existing Gitea-installed copies need their folder
renamed on disk (a-radio → rangerhq-radio) + reactivation in
WP admin. No data loss because all user-facing state lives in
user_meta under unchanged keys.

This commit is the file content for v0.7.5; the annotated tag
and push will follow the Gitea repo rename (ranger/a-radio →
ranger/rangerhq-radio) so the new tag lives in the new URL
space from the start.

+* WordPress.org slug rename: `a-radio` → `rangerhq-radio`. The previous slug was flagged as too generic for the wp.org Plugin Directory (single common functional word, no distinguishing prefix). The new slug matches the public display name "RangerHQ Radio" and lines up with the rest of the RangerHQ plugin family (`rangerhq-spatial`, `rangerhq-glyph`). Text Domain renamed to match — all 125 i18n call sites updated. Gitea repository moved to https://git.davidtkeane.com/ranger/rangerhq-radio. No user-visible behaviour change in the player; this is a packaging change only. Plugin Name stays "RangerHQ Radio"; internal constants (`RADIO_*`) and user-meta keys (`radio_state` / `radio_history` / `radio_favourites`) are unchanged so settings + history + favourites all survive intact.
+
 = 0.7.4 =
 * WordPress.org submission cleanup. Removed the self-hosted Gitea updater (`inc/updater.php`) and the `Update URI` header from `radio.php`. WordPress.org explicitly disallows both for hosted plugins (Plugin Check `plugin_updater_detected`), so updates now flow through WordPress.org as the canonical channel. Added a top-level `LICENSE` file with the full GPL v2 text and explicit GPL header blocks to `assets/css/radio.css` and `assets/js/radio.js` so the licensing of every shipped file is unambiguous. The small `Updates` panel that used to sit at the bottom of Radio → Settings is gone; player behaviour is unchanged.
