ci: parallelize gotest by separating test/cli into own job

split the Go Test workflow into two parallel jobs:
- `unit-tests`: runs unit tests (excluding test/cli)
- `cli-tests`: runs test/cli end-to-end tests

test/cli takes ~3 minutes (~50% of total gotest time), so running
it in parallel should reduce wall-clock CI time by ~1.5-2.5 minutes.

both jobs produce JUnit XML and HTML reports for consistent debugging.
