 * All strategies respect `argCount` for overload narrowing.
 * `ancestryOverride` replaces the default walk; caller must compute it correctly.
 *
 * Strategy summary (full docs in gitnexus-shared/mro-strategy.ts):
 * - `first-wins` / `leftmost-base` / `implements-split`: BFS, first match wins.
 * - `c3`: C3-linearized order; falls back to BFS on cycle/inconsistency.
 * - `qualified-syntax`: returns undefined immediately (Rust requires explicit syntax).
 * - `ruby-mixin`: kind-aware walk — see inline comments below.
 *
 * Internal API: exported for call-processor resolvers and tests.
 * External callers should use resolveMemberCall instead.
 *
 * @see gitnexus-shared/mro-strategy.ts § 'ruby-mixin'
