feat: add uwf log subcommands (list, show, clean)

- uwf log list: list log files with sizes
- uwf log show --thread <id>: filter by thread ID
- uwf log show --process <pid>: filter by process ID
- uwf log clean --before <date>: delete old log files
- Tests: 12 new tests covering all subcommands

Implemented by solve-issue workflow, biome fixes applied manually.

Closes #413
Refs #411, #410
