Change the default-hidden message categories from [thinking,
hook_progress] to [tool_result, system_message, hook_progress,
file_snapshot]. This hides the verbose machine-oriented categories
by default while keeping thinking blocks visible — they contain
useful reasoning context that users typically want to see.
Also rename the "summary" category label from "Summaries" to
"Compactions" to better reflect what Claude's summary messages
actually represent (context-window compaction artifacts).
Tests updated to match the new defaults: the filter test now
asserts that tool_result, system_message, hook_progress, and
file_snapshot are all excluded, producing 5 visible messages
instead of the previous 7.
