Ensures minimap room indicator updates

[LiquidityC]

It would only update when entering a previously unvisited room. This is
fixed now.

Summary by CodeRabbit

• New Features
  • Minimap now includes a clear highlight overlay for the current room, making it easier to orient yourself at a glance.
  • The position indicator refreshes every update cycle for more responsive, real-time feedback during gameplay.
  • Existing minimap visuals remain unchanged; the new overlay sits on top to emphasize your location without altering the base map.

Walkthrough

Adds a new public function gui_update_minimap_pos for rendering a per-room overlay on the minimap. Updates gui_update_minimap to reset the render target. Integrates gui_update_minimap_pos into the main update loop to refresh the overlay each cycle.

Changes

Cohort / File(s)	Summary
GUI API additions src/gui.h	Declares new public function void gui_update_minimap_pos(Gui *gui, Camera *cam, RoomMatrix *rm); with documentation, placed after gui_update_minimap.
Minimap rendering implementation src/gui.c	Implements gui_update_minimap_pos that renders the current-room overlay to gui->miniMapOverlay->textures[0]->texture, clearing with transparency and restoring the default render target. Ensures gui_update_minimap ends by resetting the render target to NULL.
Main loop integration src/main.c	Calls gui_update_minimap_pos(gGui, gCamera, gRoomMatrix) in run_game_update after map_clear_expired_entities and repopulate_roommatrix.

Poem

A hop, a skip, a minimap glow,
I nudge the room where heroes go.
Overlay bright, I set the scene—
Tiny squares where quests have been.
Thump-thump! my paws applaud the art,
New trail marked on the rabbit’s chart.
