feat(sounds): self-made Ogg cues + watch/mute/pop fixes

Replace ripped Discord audio with self-authored Ogg Vorbis files (avoids
copyright on open-source launch) and fix three cue bugs:

- Anti-pop envelope: playSound now applies a 10ms fade-in (+ tail fade-out
  for one-shots) so buffers no longer start at a non-zero amplitude. Kills
  the pop on the looping call cues. Mirrors playTestTone.
- Deafen no longer plays mute+deafen at once: toggleDeafen flips isMuted and
  isDeafened atomically, so SoundController saw both transitions. New tested
  pure helper selectVoiceStateSound() suppresses the side-effect mute cue.
- Viewer-side watch feedback: stream_user_joined/left now play locally on the
  watcher's own machine for explicit Watch/Stop actions, via
  handleViewerWatchToggle. Direct local playback (not a watchingStreams diff)
  keeps auto-teardown silent and works identically on Safari and Electron.

Docs: docs/systems/sounds.md updated (Ogg, dual-audience cue rows, mute/deafen
selection, viewer feedback, anti-pop envelope).

Single source of truth for the in-app audio cue layer. Files live in
`packages/web/public/sounds/` as **Ogg Vorbis** (`.ogg`). Most cues are wired
to exactly one event; the two `stream_user_*` cues are dual-audience (see
their rows). All cues are self-authored (no third-party/Discord audio).

connect because the keyed lookup resolves only once `currentVoiceChannelId` is

### Mute/deafen cue selection
Deafening is not independent of muting: `voiceStore.toggleDeafen` flips
`isMuted` together with `isDeafened` in a single atomic `set()` (deafen ⇒
muted, undeafen ⇒ unmuted), mirroring Discord. SoundController samples both
effective states on the same store tick, so firing a cue per changed flag would
play `mute` **and** `deafen` at once when the user hits deafen.
`selectVoiceStateSound(prev, next)` (`utils/voiceSoundTransitions.ts`) resolves
this to a single cue: if the deafen state changed it returns `deafen`/`undeafen`
and the coincident mute change is treated as a side effect and suppressed;
otherwise a mute change returns `mute`/`unmute`. Pure helper, unit-tested.
### Viewer-side watch feedback
`stream_user_joined` / `stream_user_left` also play on the **viewer's own**
machine as feedback for an explicit watch/stop action, via
`handleViewerWatchToggle` in `StreamTile.tsx` — the same chokepoint that
broadcasts the `stream_watch` ping. The cue is played directly (not derived
from a `watchingStreams` diff) for two reasons: (1) automatic teardown paths
(streamer stops sharing, participant disconnect) mutate `watchingStreams`
without being the viewer's action and must stay silent on the viewer side —
they already get `stream_ended`; (2) a direct local play is independent of the
data-channel round-trip to the streamer, so the viewer gets identical feedback
on every platform (Safari and the Electron desktop app alike). This is
orthogonal to the streamer-side diff below, which fires on a *different*
machine for that streamer's watcher set — the two never double on one client.
### Playback envelope (anti-pop)
`AudioManager.playSound` wraps every cue in a short gain envelope — a 10ms
fade-in on start and (for non-looping cues) a 10ms fade-out before the buffer
ends. Starting a buffer at a non-zero sample amplitude produces an audible
click/pop; the envelope removes it. Most noticeable on the looping call cues
(`call_calling` / `call_ringing`), which previously popped on every start.
Mirrors the envelope already used by `playTestTone`.
