BaseTestCase::create_mock_wpdb() only adds methods
[prepare, get_var, get_results, insert, query, get_row, update] — the
reaper and amortize_research_costs also call `delete` and `get_col`,
which the default mock can't stub. CI on PR #100 fired all five new
ResearchReaperTest cases as errors at the first `->method('delete')`
call during setUp.
Fix: build a bespoke $wpdb mock in this file's setUp with the full
superset of methods it needs. Self-contained; no change to
BaseTestCase so existing tests aren't affected.

Covers the five scenarios from convo thread research-cost-reaper seq 1:
- test_reaps_orphan_with_matching_run_id_posts — meta lookup returns
two post IDs; reaper delegates to amortize_research_costs which
inserts two rows and deletes the orphan.
- test_skips_orphan_within_grace_period — the SELECT's
`created_at < now - 1h` clause filters fresh orphans at the DB; the
reaper's stats stay zero and no side effects fire.
- test_deletes_orphan_with_no_articles_after_7_days — orphan is 8 days
old, zero siblings via meta or gen_log; reaper deletes outright.
- test_falls_back_to_gen_log_when_post_meta_missing — meta returns
empty (legacy pre-v0.8.1 post); gen_log has two distinct post_ids;
amortize still runs.
- test_idempotent_on_repeat_run — second pass on a cleaned state
returns 0/0/0 with no inserts or deletes.
All DB interaction mocked via $wpdb stub — no real DB round-trips.
Fixtures are driven by property mutations in the test methods so
PHPUnit's "one stub per method" restriction on mocks doesn't bite.
Part of the v0.8.1 bundle.
