Why

sendspin-cpp#218 merged as 3a3722a8. It adds SendspinClientConfig::application_roles, which #110 needs for local pairing. Moving the pin there also brings sendspin-cpp#234, which removes ConnectionTrust and on_trust_changed() in favour of SendspinClient::is_paired(), so the pin cannot move without this migration.

What

• Pin 3a3722a8, 31 commits past b0fcf5bb.
• PairingListener drops the callback and polls is_paired() once per main-loop tick, reading it before is_connected() as the library asks. It still logs Connected server is paired / not paired when a session is new or has been re-keyed, and still clears a stale pairing attempt then.
• status reads is_paired() before is_connected() too. The trust line is paired, unpaired or not connected as before. unknown is gone: a connected session is always one or the other.
• docs/ROADMAP.md item 3 names the new pin.

Compatibility

No flag, config key, control-socket message, state format or exit code changes. The only visible difference is that status no longer prints trust: unknown.

Testing

Ubuntu 24.04, Release, -DSENDSPIN_CLI_WERROR=ON, ALSA, PulseAudio, PipeWire, PortAudio and Avahi, fresh FetchContent:

• scripts/format.sh --check: every file is formatted.
• --version reports sendspin-cpp 3a3722a8….
• ctest: 554 of 557 pass. The three failures are StateStore.AnUnwritableDirectoryFails, AFailedWriteIsNotRememberedAsASuccess and WritesVolumeAndMuteInOneGo. Each makes a directory read-only and expects a write to fail, and the run was as root, which writes regardless. This PR doesn't touch the state store, and CI runs them unprivileged.
• scripts/smoke_test.sh: every check passed.

🟡 Changes recommended

Clearing server_id_ on the first connected tick can discard a newly started pairing attempt and incorrectly report pairing: none; the callback ordering needs a fix and regression test.

What changed in this PR

Updates sendspin-cpp to 3a3722a8, enabling the application-role support needed for local pairing in #110, and migrates pairing state to the new is_paired() API.

Changes:

• Re-pins the dependency and updates the roadmap reference.
• Replaces trust callbacks with main-loop polling and direct pairing-state reads for status.
• Updates status formatting and tests to remove the unknown trust state.
