v0.2.1

Fixes

• --stream-dir for plugin subcommands — brooklet scout scan and brooklet pytest scan now accept --stream-dir (env: BROOKLET_DIR) so --output topics write to a user-chosen directory instead of the data source directory
• Scout --output error handling — stream.produce() failures now warn gracefully instead of crashing with a raw traceback (matching pytest plugin behavior)
• Lazy stream opening in pytest — batch mode no longer creates .brooklet/ metadata directories unnecessarily; streams only open when --output or --follow requires them
