fix(ci): tier the risk floor by fork only and stop counting conditional skips

The author factor now only raises a PR to high when it comes from a fork,
so an internal human-opened docs or test-only PR can reach the low tier
the one-pager's tier 0 needs. Over the last 400 staging merges that moves
the low count from 2 to 29 with no reverted merge among them

Skip markers only count when they silence a test unconditionally:
pytest.mark.skipif, unittest.skipIf/skipUnless, a guarded pytest.skip(),
and Playwright's conditional test.skip(cond, reason) no longer rank a PR
high. Test directories anywhere in the tree count as test files, and the
enterprise auth and management endpoint packages join the always-human
paths
