Detailed Description

Purpose
-------
OI-510 / FS-516 regression coverage — :func:`build_test_index` must
walk ``tests_dir`` exactly once per linter run and produce two lookup
sets on :class:`LinterContext`. :func:`check_tests_exist` then becomes
O(1) per call, replacing the previous O(N·M) rglob-and-read loop that
dominated ``oct lint`` runtime on medium-to-large projects.

Responsibilities
----------------
- Verify first call builds and caches ``ctx.test_index``; subsequent
  calls return the cached dict without re-walking.
- Verify both naming-convention and import-statement paths populate the
  index.
- Verify ``check_tests_exist`` returns True for either lookup path.

Diagnostics
-----------
Domain: LINTER-TESTS
Levels:
    L2 — test lifecycle
    L3 — assertion details
    L4 — deep tracing

Contracts
---------
- First call builds and caches ``ctx.test_index``; subsequent calls
  return the cached dict without re-walking.
- Both naming-convention and import-statement paths populate the index.
- ``check_tests_exist`` returns True for either path.
