Release 0.4.0

On-radio channel add/delete from the Channel quick menu (with translations and a
Managing-channels manual section), flash.sh always rebuilds language packs, and
releases before v1.0.0 are flagged as pre-releases.

Bump version to 0.4.0.

+## Managing channels on the radio
+
+FreeTRX can create and delete channels without a PC. Both actions live in the
+**Channel quick menu** — from the Channel screen, press the **top (orange)
+button** to open it, then scroll to the bottom:
+
+- **New channel** — creates a blank **145.500 MHz FM** channel in the first free
+  slot, adds it to the current zone, and opens **Channel Details** so you can set
+  the name, frequency, tones, and so on. Press the **green** key to save. The new
+  channel is immediately selectable in the zone (no need to re-enter it).
+- **Delete Channel** — deletes the currently-selected channel after a
+  confirmation (**green** confirms, **red** cancels). It is also scrubbed from
+  every zone that referenced it. The last remaining channel cannot be deleted,
+  and channels locked read-only (e.g. APRS) are protected.
+
+> **Back up your codeplug** (via the CPS) before making bulk edits — these changes
+> are written straight to the radio and there is no on-device undo.
