Release: bump to v0.3.1

One user-facing fix since v0.3.0:

  * 2e29385 URLs: percent-encode non-ASCII bytes before
    launching the browser. URLs with Cyrillic/CJK/accented
    characters in their path or query (e.g. Reddit thread URLs
    containing the original-language title) failed `b` on macOS
    with "Error 92: Illegal byte sequence" because NSURL / `open`
    reject anything outside RFC 3986. Now `iri_to_uri()` walks
    the string and percent-encodes any byte >= 0x80; ASCII
    (including `%` and the URL-reserved set) passes through
    unchanged, so the URL structure is preserved and the
    operation is idempotent on already-encoded input. Harmless
    on Windows (ShellExecute accepts UTF-8 URLs as-is; the
    browser sees the percent-encoded form and normalizes
    identically) and necessary on macOS.
