Fix orphaned test false positives on behavioral/scenario test names

[chubes4]

Summary

Fixes #1120 — the orphaned test detector was deleting valid tests via autofix.

Root cause: The behavioral heuristic in find_orphaned_test_methods() used first-word matching that was too loose. Common verbs like apply, resolve, build matched source methods with those prefixes, causing scenario test names to be incorrectly flagged as orphaned.

Example from PR #1119: Test apply_replace_text (a scenario test for apply_edit_ops_to_content()) was flagged because:

1. Strip test_ → apply_replace_text
2. No exact source method match
3. Behavioral filter: first word apply matches source method apply_edit_ops → not skipped
4. Flagged as orphaned → autofix deleted it

Fix: Replace first-segment matching with direct-prefix matching. 3+ segment test names are now treated as behavioral (skipped) UNLESS the full expected source name is a direct prefix of a source method name. This is more conservative — some real orphans with 3+ segments may not be caught, but we stop deleting valid tests.

Changes

• test_coverage.rs: Updated behavioral heuristic in find_orphaned_test_methods()
• Updated existing test expectations (inline orphan test now expects 1 finding instead of 2)
• Added regression test scenario_test_names_not_flagged_as_orphaned covering the exact PR feat: Add apply logic for EditOp (Phase 1 of #1041) #1119 scenario

Test results

22/22 test_coverage tests pass. Full suite: 1087 tests, 0 failures.
