Subject: [PATCH] fix: cookbook guess_version falls back to '0.1.0' instead of
 None
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When recipe has no [package].version, no parseable tar URL version,
no git rev/branch version, no Cargo.toml version, and no directory-name
version — fall back to '0.1.0' instead of failing with 'cannot guess
version'. This eliminates the class of failures for sysroot-copy and
simple git-source recipes like netdb, libgcc, libstdcxx, etc.
