Update README and API header for v0.7.0

Adds World Markers section (new module shipping in 0.7.0). Updates the
Performance section with Lua runtime optimizations (allocator, GC,
string interning, pattern prefilter). Fixes Log Sessions documentation
to reflect per-day rollover. Adds worldmarkers, clickthrough, and
weirdperformance to the DLL auto-discovery list in weirdutils_api.h.

 ## Features
 
+### World Markers
+
+Place up to 5 animated colored markers (Cataclysm style) at any position in the world, useful for raid positioning, pull planning, or route marking. Requires party/raid leader or raid assist.
+
+- `/worldmarker 1` through `/worldmarker 5` (or `/wm 1`) -- place a marker where your cursor is pointing
+- `/worldmarker 1 target` -- place a marker on a unit (player, target, mouseover, etc.)
+- `/clearworldmarker` (or `/cwm`) -- remove all markers
+- `/clearworldmarker 2` -- remove a specific marker
+
+Keybindings for placing each marker and clearing all markers are available in the Key Bindings menu.
+
+Markers automatically sync with group members who also have WeirdUtils installed. When a leader/assist places or clears a marker, all group members see it. Markers persist across zone transitions and respawn when you return to the area.
+
+Lua API for addon developers:
+
+- `WorldMarker(index)` -- place marker at cursor (returns x,y,z,areaId on success, nil if no permission, -1 on failure)
+- `WorldMarker(index, "unit")` -- place marker at a unit's position
+- `WorldMarker(index, x, y, z)` -- place marker at world coordinates
+- `ClearWorldMarker(index)` / `ClearWorldMarker()` -- remove one or all markers (returns 1 on success, nil if no permission)
+- `GetWorldMarker(index)` -- returns x,y,z,areaId for an active marker, nil if empty
+- `CanSetWorldMarker()` -- returns 1 if the local player is party/raid leader or raid assist, nil otherwise

 ### Module Mutexes
 
-Each module also holds a named mutex while active: `Local\WeirdUtils_<name>_<PID>` (e.g. `Local\WeirdUtils_transmogfix_12345`). The exception is transmogfix, which uses `Local\TransmogCoalesceHook_<PID>` for legacy reasons.

 If you see the mutex, the module is loaded - and can use the Runtime Module Control API to disable it. If you don't see it, the module isn't active and you're free to hook those functions yourself.
