Basic Action Update

Version 0.0.2

• Fixed the placement latch. A hard placement failure now blocks upgrades until /bau scan or a reload. /bau status reports the block, and /bau scan names the reason instead of printing "upgraded 0 of N".
• A blocked placement now retries once after 5 seconds. If that retry fails too, the addon stays latched and prints a warning in chat.
• Skips are counted only while a scan is running, so /bau status and /bau debug cannot inflate the number. /bau status and /bau scan report the count from the last scan.
