feat(playback): keep the computer awake while music plays - #835
Conversation
A desktop idle suspend stopped albums midway, on GNOME notably. A sleep inhibitor is held while playing and released on pause or stop: the desktop portal's Inhibit on Linux, SetThreadExecutionState on Windows, nothing on macOS where coreaudiod already asserts. A suspend the user asks for still happens. On by default, with a setting in Playback.

The command now takes the expected profile id and leases the pool with require_profile_pool_for, so a profile switch in flight cannot redirect the write or the inhibitor.

The inhibitor is process-wide: the command now applies it under the profile lock, and only if the profile that received the write is still the active one, so a switch in between keeps the next profile's own value.

Two calls interleaving between the SQL write and set_enabled could leave the inhibitor on the earlier value; a static mutex now covers the whole sequence.
1.9 board item: "Keep the computer awake while music plays".
Why
A desktop that sees no input for its idle delay suspends whatever is playing; reported on GNOME, where the idle suspend runs in the middle of an album.
What
New
power.rs: one worker thread (waveflow-power) holds a sleep inhibitor while the player isPlayingand the setting is on, and releases it on pause / stop / idle or when the setting is turned off. It never blocks a suspend the user asks for (lid, Sleep).org.freedesktop.portal.Inhibit(suspend | idle), released withRequest.Close. GNOME and KDE route it into their own power management, and it works inside the Flatpak with no extra permission. A logindidlelock would not reach GNOME's auto-suspend; a logindsleeplock inblockmode would refuse even a requested suspend. Without a portal, the failure is logged once and nothing else changes. Uses thezbus5 already in the tree (checked separately against zbus 5.19 forx86_64-unknown-linux-gnu, since nothing compiles this module on Windows).SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED), cleared withES_CONTINUOUS. The state belongs to the calling thread, hence the single worker. Only awindowsfeature (Win32_System_Power) is added, no new crate, no lockfile change.coreaudiodalready asserts while audio plays.Fed by
transition_state(non-blocking send;Loadingskipped so the lock is not dropped and retaken between tracks). Process-wide like the offline mode, so the profile settings loader reaches it without anAppHandle.Setting
profile_setting['playback.keep_awake'], on by default, read on every profile load;player_set_keep_awakepersists and applies it; exposed inplayer_get_audio_settings. Settings → Playback → Listening: "Keep the computer awake while playing", same write discipline as "Pause on device loss" (serialized, dropped on a profile switch, rolled back on failure). 17 locales.Not in this PR: pausing cleanly when the machine suspends anyway (the card's second half).
