Split the monolithic who.rs into a who/ directory module with 7 focused
files. The 5 query modes (expert, workload, reviews, active, overlap) share
no query-level code — only types and a few small helpers — making this a
clean mechanical extraction.
New structure:
who/types.rs — all pub result structs/enums (~185 lines)
who/mod.rs — dispatch, shared helpers, JSON envelope (~428 lines)
who/expert.rs — query + render + json for expert mode (~839 lines)
who/workload.rs — query + render + json for workload mode (~370 lines)
who/reviews.rs — query + render + json for reviews mode (~214 lines)
who/active.rs — query + render + json for active mode (~299 lines)
who/overlap.rs — query + render + json for overlap mode (~323 lines)
Token savings: an agent working on any single mode now loads ~400-960 lines
instead of 2,598 (63-85% reduction). Public API unchanged — parent mod.rs
re-exports are identical.
Test re-exports use #[cfg(test)] use (not pub use) to avoid visibility
conflicts with pub(super) items in submodules. All 79 who tests pass.
