Release v4.3: speak status line (Tolk) + Logging tab with housekeeping

- New screen-reader hotkey "Speak the RemSound status information" (issue #13):
  reads the status line aloud through the active screen reader via Tolk, fires from
  anywhere (system-wide), unset by default. Built behind an IScreenReaderOutput seam
  so a future build can swap Tolk for Prism on Windows 10+ without touching callers.
  Tolk DLLs vendored under tolk/ and shipped next to the exe.
- New Logging tab in Preferences: Enable logs + Write logs now moved there, plus
  opt-in startup "warn if logs folder exceeds N MB" and "delete logs older than N days",
  and a "Delete all logs" button (Yes/No confirm). New LogMaintenance helper + AppConfig
  settings drive it.
- Manual (readme.html + regenerated MANUAL.md), About changelog and RELEASE_NOTES
  updated in plain English; csproj <Version> bumped to 4.3.

+### Hearing the RemSound status on demand
+
+The main window has a **status line** that updates every second with how long you've been connected, how many peers you have, whether sound is flowing, and how healthy the connection is. Normally your screen reader reads it like any other text — but now and then, for reasons that have nothing to do with RemSound, a screen reader loses sight of it and says there's nothing there.
+
+This hotkey is the cure. Give **Speak the RemSound status information** a key in the Keyboard shortcuts dialog, and from then on pressing it reads the whole status line out loud, wherever you are — even when RemSound is tucked away in the tray or another program is in front. It's unset to start with, so the key is yours to choose.
+
+This one is just for screen-reader users: it talks straight through your screen reader. It works with the screen readers RemSound's speech helper supports — **NVDA** , JAWS, Window-Eyes, System Access, SuperNova and ZoomText — and falls back to Windows' own built-in speech if none of those is running. If you don't use a screen reader, just leave this one unset.
+
 ### Your screen reader reads out the hotkeys
 
 Once a hotkey is set, your screen reader reads it out whenever you land on the menu item or control it's tied to — for example, moving onto **File → Open profile** announces “Ctrl+O”, and a control with a global hotkey announces “press [your key] anywhere”. So you can learn and confirm your shortcuts just by arrowing around the window, without coming back to this dialog.

+### Keeping the logs folder tidy
+
+Log files are small, but if you leave logging on for months they add up. The **Logging** tab has three ways to keep the folder under control, all switched off to begin with so nothing is ever deleted unless you ask for it:
+
+  * **Warn at startup if the logs folder is larger than … megabytes** (Alt+S) — tick this and pick a size, and the next time RemSound starts it checks the folder and pops up a friendly notice if it has grown past that size. It only warns; it never deletes anything itself. The size box (Alt+M) starts at 100 megabytes and stays greyed out until you tick the box.
+  * **Delete logs older than … days old** (Alt+D) — tick this and pick a number of days, from 1 to 30, and each time RemSound starts it quietly clears out any log older than that. The log it's writing right now is never touched. The days box (Alt+Y) starts at 14 and stays greyed out until you tick the box.
+  * **Delete all logs** (Alt+A) — a button that clears out every log file in one go. It asks you to confirm first, Yes or No, then tells you how many it removed. Again, the log RemSound is writing right now is kept; everything else goes.
