tools: viewport capture + cache-bust rebuild harness

screen_capture DOES work via the bridge (capture_id='ScreenCapture_1'); the prior assumption that the Studio viewport couldn't be captured from this box was wrong. capture_shots.py sets the Edit camera per shot and pulls a jpg for each angle. rebuild_cachebust.luau documents the require() cache trap: pushing new .Source does not invalidate the per-instance module cache, so a rebuild silently runs the OLD code and the diagnostic reports already-fixed failures. Swapping in Clone()s at the same paths forces a fresh compile.

+"""Capture a set of Studio viewport angles of the Daikoku PA junction.
+
+Sets the Edit-mode camera via execute_luau, then pulls a screen_capture for
+each shot. Bridge calls are slow (~30-60s each), so this runs as one batch.
+
+NOTE (corrects an old assumption): screen_capture DOES work on this setup.
+It needs capture_id='ScreenCapture_1'. Earlier notes claimed the Studio
+viewport could not be screenshotted from wks-victus -- that was wrong.
