v0.19.2

This is a bugfix and small-feature release.

New features

• Support RFC 6762 legacy unicast responses: when a query arrives from a source port other than 5353, the daemon now replies directly to the querier's address/port instead of multicasting. This enables interoperability with one-shot / legacy mDNS queriers. (#469, commit 933bdbe)
• Added a new Error::DaemonShutdown variant, returned by ServiceDaemon methods after the daemon thread has exited (previously surfaced as a generic Error::Msg). The Error enum is #[non_exhaustive], so this is additive. (commit a457193)

Bug fixes / improvements

• Optimize outgoing DNS serialization to reduce allocations on the send path. (#467, commit fb26d7f)
• Replace a stray println! in DnsHostInfo::write with debug!, so the library no longer writes to stdout. (#465, commit 96008a4)
• Expanded # Errors doc sections on the major ServiceDaemon APIs (new, new_with_port, browse, stop_browse, resolve_hostname, stop_resolve_hostname, register, unregister), documenting when Error::Again vs. Error::DaemonShutdown is returned. (#464, commit a457193)
