Subject: [PATCH 1/2] fix(task): include args in task output prefix and
 truncate long prefixes

When the same task runs multiple times with different arguments (e.g. as
dependencies in a test matrix), all output was prefixed with just the task
name, making it impossible to distinguish runs. Now args are included in
the prefix (e.g. `[test-docker 4.1]`) and long prefixes are truncated to
40 chars.

Closes https://github.com/jdx/mise/discussions/8531
