What does this change?

Prepares the 0.3.0 release: chat, phone GPS for your radio, and radio details (plus Meshtastic SDK 0.2.0).

• versionCode 5 → 6, versionName 0.2.0 → 0.3.0 (app/build.gradle.kts, noted in AGENTS.md).
• CHANGELOG.md: "Unreleased" becomes ## 0.3.0, with a one-line summary and an "Updating" note: install over 0.2.0, what MeshAnd now transmits, and when it asks for location. The release workflow publishes this section as the release text.
• Website (site/public/index.html): the "Next version" badges on Chat, Phone GPS and Radio details are removed. "Remembers trails, pins and messages".
• README.md: adds Chat and Phone GPS feature cards and Radio details under "Also". "Mostly just listens" now says what is sent (messages and pins, plus the phone position to your own radio while Phone GPS is on).

After merging, tag v0.3.0 on the merge commit. release.yml builds, signs and publishes MeshAnd-0.3.0.apk.
