Filter UV package installation output from HF Jobs logs

Adds filtering to reduce UV package installation noise in job logs
while preserving the installation summary for context.

Changes:
- Add _filter_uv_install_output() function with regex pattern matching
- Apply filter in _run_job() before returning logs to agent
- Replace installation details with "[installs truncated]" message
- Keep "Installed X packages in Y ms/s" summary line visible
- Supports singular/plural, ms/s units, and decimal time values
- Add comprehensive tests covering various edge cases

Example output:
[installs truncated]
Installed 68 packages in 251ms
Running main script...
Hello from the job!
