chore(#516): cut 1.4.0+65

Bump pubspec to 1.4.0+65 and add the four release-gate docs for the
follow-up to the 1.3.0 launch: button/buzzer settings for headless
devices (#483), Send Again on channel messages (#513), caps byte 2 in
Device Info (#480), and per-radio data-correctness fixes (#505/#506,
#472, #425, #495, #497).

+## [1.4.0] - 2026-07-30
+
+A follow-up to the 1.3.0 production launch: settings for headless devices, a
+resend action for channel messages, and a batch of per-radio data-correctness
+fixes.
+
+### Added
+
+- Button and buzzer settings for headless devices, capability-gated so they only
+  appear on radios that report support (#483).
+- "Send Again" resend on channel messages, with the direct-message resend action
+  relabeled to match (#513).
+- Device Info shows the second offband capabilities byte, so more capability bits
+  are visible at a glance (#480).
+- `@[name]` self-mention matching is now ASCII case-insensitive, so a mention
+  matches regardless of case (#486).
+
+### Fixed
+
+- Block list is scoped per radio again: an accidental global block list was dropped,
+  so blocking on one radio no longer leaks to another (#505, #506).
+- Per-radio in-memory caches are cleared on reconnect, so data from a previously
+  connected radio cannot linger into the next session (#472).
+- Translation-model downloads retry transient 5xx errors with backoff instead of
+  failing outright, and the backoff tracks actual elapsed time (#425).
+- `@[name]` mentions are treated as a verbatim wire token (no stray trim), matching
+  the reference contract (#497).
+- Routed replies are sent at the contact's path-hash width instead of width 1
+  (#495).
+
+### Under the hood
+
+- CI now guards against em-dash characters in `lib/` and `test/` (#464).

+## Offband Meshcore 1.4.0
+
+A focused follow-up to the 1.3.0 production launch: new settings for headless
+devices, a resend action on channel messages, and a set of per-radio
+data-correctness fixes.
+
+### New
+
+- **Button and buzzer settings for headless devices.** On radios that report
+  support, you can now configure the button and buzzer right from settings,
+  capability-gated so the controls only show where they apply (#483).
+- **"Send Again" on channel messages.** Resend a channel message in one tap, with
+  the direct-message resend action relabeled to match (#513).
+- **More capability detail in Device Info.** The second offband capabilities byte is
+  now shown, so more of your radio's capability bits are visible at a glance (#480).
+- **Case-insensitive self-mentions.** An `@[name]` mention of yourself now matches
+  regardless of case (#486).
+
+### Fixed
+
+- **Block list is per-radio again.** An accidental global block list was dropped, so
+  blocking someone on one radio no longer carries over to another (#505, #506).
+- **Clean slate on reconnect.** Per-radio in-memory caches are cleared on reconnect,
+  so data from a previously connected radio can't linger into the next session
+  (#472).
+- **Sturdier translation-model download.** Transient server errors now retry with
+  backoff instead of failing the download outright (#425).
+- **Mention and routing correctness.** `@[name]` mentions are handled as a verbatim
+  wire token, and routed replies are sent at the contact's path-hash width instead
+  of width 1 (#497, #495).
