Bump to v3.1.0: new audio cues (save, profile-switch), per-profile custom cue paths, redesigned tray menu

Two new cues join the existing connect / disconnect / record-start /
record-stop set:
  * profile-save cue (sounds\save.wav by default) fires in
    SaveProfileTo after a successful Save or Save As. Honours the
    Profile.EnableSaveCue per-profile flag.
  * profile-switch cue (sounds\profile.wav by default) fires in the
    MainForm Shown handler after a profile finishes loading - covers
    both startup-with-profile and mid-session profile switches.
    Honours the Profile.EnableProfileSwitchCue flag. Because cue
    loading runs AFTER settings.ApplyProfile in the ctor (line 542),
    the profile being entered determines which sound plays - not the
    one being left, exactly as Ed asked.

The audio cue UI in PreferencesDialog stays as a CheckedListBox (up /
down navigates, Space toggles) with TWO action buttons below that
operate on whichever cue is selected:
  * Play [cue name] (Alt+P) - previews via SoundPlayer.Play on the
    resolved path (custom override if set, default in sounds\
    otherwise). Independent of the tick state.
  * Browse for [cue name]... (Alt+B) - opens a WAV picker. If the
    user picks a file inside RemSound's own sounds\ folder, it's
    treated as "use default" and the override is cleared - avoids
    pinning the user to a specific shipped default that a future
    release might replace. Right-click "Use default sound" reverts.

Custom cue paths AND enable flags are per-profile. Lives on
Profile.CustomCuePaths (Dictionary<string,string>) and the per-cue
EnableXxxCue bool? properties. Cache mirror in
RemSoundSettingsStore.Settings.

All default WAVs moved from the install-root flat layout into a
sounds\ subfolder (csproj Content rules updated). save.wav and
profile.wav are bundled defaults.

Tray menu rewritten (MainFormTrayController) per Ed's spec:
  * Show RemSound (W) - now uses Win32 SetForegroundWindow after the
    standard Activate() because WinForms Activate is blocked by the
    foreground-lock when invoked from a tray-menu click, which left
    screen-reader users having to Alt+Tab to reach the restored
    window.
  * Enable sending (S) / Enable receiving (R) - tickable, reflect
    current state, TOGGLE rather than always-on.
  * Profiles (P) - submenu populated from AppConfig.RecentProfiles
    with the same &1..&5 mnemonics the File menu uses. Pre-populated
    once at construction so WinForms recognises it as a submenu and
    fires DropDownOpening - originally I relied entirely on the
    open event, which the framework skipped for items with no
    DropDownItems, producing the "Profiles does nothing" bug.
  * Exit (X).

Tray tooltip now built dynamically from snapshot tick (1 Hz):
"RemSound - [recording for MM:SS,] N peer(s), sending (lane),
receiving (lane)". Recording timer only included while
RecordingController.IsRecording is true (added
RecordingStartedUtc accessor for the elapsed calculation). Lane is
derived from which device-list ticks are active, not just the audio-
mode setting, so a BothIndependent user with only WASAPI inputs ticked
honestly reads as "sending (WASAPI)".

Fixes:
  * Initial tooltip "RemSound" produced a "RemSound RemSound" read on
    NVDA because the process name and tooltip matched. Set to
    "RemSound - starting up" so the duplicate disappears.
  * Recent profile menu items no longer carry a "Recent profile N:"
    AccessibleName prefix in either the tray submenu or the File
    menu's Recent profiles - now just the profile name. Number-key
    mnemonics (&1..&5) untouched.

Manual (readme.html) updated: new section 17 "Audio cue sounds"
documents all six cues, the Play/Browse buttons, the right-click
"Use default sound", and the per-profile semantics. Sections 17-21
renumbered to 18-22. New "System tray icon and its menu" subsection
inside section 4 documents the redesigned right-click menu and the
hover tooltip. MANUAL.md regenerated via sync-manual.py. About box
gets a v3.1 block at the top. RELEASE_NOTES.md fully rewritten for
v3.1.

No wire format change - v3.1 talks to other v3.0.x machines exactly
as before.

+
+<p>RemSound plays a short sound at moments where you might want an audible confirmation that something just happened. These are called <strong>cue sounds</strong>. Six events have a cue:</p>
+

+<tr><td><strong>Profile switched sound</strong></td><td>A profile finishes loading. Plays at startup if you started with a profile, and after every profile switch &mdash; using the new profile's cue, not the old one's.</td></tr>
+</table>
+
+<p>All six cues play through your default Windows sound output, which is separate from the audio RemSound is sending or receiving. They don't appear in a normal recording. (The exception: if your sending side is capturing the very output device the cues play through, then they get captured along with everything else from that device.)</p>
+
+<h3>Turning each cue on or off</h3>
+
+<p>Open <strong>File &rarr; Preferences</strong> (or Ctrl+P). The <strong>Audio cue sounds (Alt+N)</strong> list shows all six cues with a tickbox next to each. Tick to play the cue when the corresponding event happens; untick to silence it.</p>
+
+<p>Use the up and down arrow keys to move between cues; press <strong>Space</strong> to toggle the highlighted cue's tick on or off.</p>
+
+<p>The tick settings are <strong>saved with the active profile</strong>, so different profiles can have different combinations of cues on. For example, a &ldquo;quiet listening&rdquo; profile might have all cues off, while a &ldquo;live monitoring&rdquo; profile keeps them on. When you save the profile (Ctrl+S), the new settings travel with it.</p>
+
+<h3>Previewing and choosing a different sound</h3>
+
+<p>Below the list are two buttons that act on whichever cue is currently highlighted in the list:</p>
+
+<ul>
+<li><strong>Play [cue name] (Alt+P)</strong> &mdash; previews the cue's currently-configured sound through your default Windows output, so you can hear it without having to trigger the event. Works regardless of whether the cue is ticked (so you can listen before deciding to enable it).</li>
+<li><strong>Browse for [cue name]&hellip; (Alt+B)</strong> &mdash; opens a Windows file picker so you can choose your own WAV file for this cue, replacing the default. RemSound only accepts <code>.wav</code> files. Once picked, the button's label changes to &ldquo;(custom)&rdquo; to remind you the cue is using your file rather than the default. The next time the event fires, your custom sound plays.</li>
+</ul>
+
+<p>Both buttons' labels update as you arrow through the list, so you always know which cue you're about to act on.</p>
+
+<p>Custom sound choices are <strong>saved with the active profile</strong>, the same way the tick states are. Different profiles can have completely different cue palettes &mdash; a &ldquo;studio&rdquo; profile might use one set of sounds, a &ldquo;broadcast&rdquo; profile another. The custom files themselves stay where you picked them on your disk; the profile just remembers their paths.</p>
+
+<h3>Going back to the default sound</h3>
+
+<p>To revert a cue to its default sound, <strong>right-click</strong> the <em>Browse for [cue name]&hellip;</em> button and pick <strong>Use default sound</strong>. The custom path is forgotten and the cue goes back to playing the default WAV that ships with RemSound. The right-click option is greyed out when the cue is already using its default. (Alternatively, click <em>Browse</em> and pick a file from inside RemSound's own <code>sounds</code> folder &mdash; RemSound recognises that as &ldquo;use default&rdquo; and clears the override automatically.)</p>
+
+<h3>Where the default sounds live</h3>
+
+<p>The default WAV files are in the <code>sounds</code> folder next to <code>RemSound.exe</code>. If you don't pick a custom file for a cue, RemSound plays the matching default from there:</p>
+
+<ul>
+<li><code>sounds\connect.wav</code> &mdash; connect cue</li>
+<li><code>sounds\disconnect.wav</code> &mdash; disconnect cue</li>
+<li><code>sounds\record start.wav</code> &mdash; recording start cue</li>
+<li><code>sounds\record stop.wav</code> &mdash; recording stop cue</li>
+<li><code>sounds\save.wav</code> &mdash; profile saved cue</li>
+<li><code>sounds\profile.wav</code> &mdash; profile switched cue</li>
+</ul>
+
+<p>If a cue's WAV file is missing &mdash; either the default file doesn't exist or a custom path points at a file you've since deleted &mdash; the cue stays silent rather than producing an error. RemSound logs a note in the diagnostic log (if logging is on) so you can see what happened.</p>
+
+<div class="note">
+<strong>Tip for sound designers:</strong> the defaults are deliberately short and simple so they stay out of the way. If you'd like the cues to feel more in-character with a particular profile, the custom-sound feature is designed for exactly that. Keep WAV files short (well under a second usually works best) so cues don't overlap with each other on a busy day.
