// ResolveBase: resolve a 多维表 Base by name keyword into a single baseId.
//
// This is the Base-level analogue of "resolve a user by name". It searches
// Bases by name and disambiguates:
//   - search Bases via search_bases (mirrors helpers base search, MCP arg
//     "query" ← --name);
//   - project each candidate to {baseId, name} — field parsing is defensive
//     (multiple candidate keys);
//   - exactly one match → return {resolved:true, baseId, name};
//     multiple matches → return {resolved:false, count, candidates} and let
//     the caller pick (never guesses);
//     zero matches → report a validation error instead of an empty raw dump.
//
// Read-only: it only searches and reshapes, never mutates any Base.
//
