Replace hardcoded truncation widths across CLI commands with
render::flex_width() calls that adapt to terminal size. Remove
server-side truncate_to_chars() in timeline collect/seed stages so
full text is preserved through the pipeline — truncation now happens
only at the presentation layer where terminal width is known.
Affected commands: explain, file-history, list (issues/mrs/notes),
me, timeline, who (active/expert/workload).
When `--limit` is omitted, the default value is `usize::MAX` to mean
"unlimited". The previous code used `(limit + 1) as i64` to fetch one
extra row for "has more" detection. This caused integer overflow:
usize::MAX + 1 = 0 (wraps around)
The resulting `LIMIT 0` clause returned zero rows, making the `who`
subcommands appear to find nothing even when data existed.
Fix: Use `saturating_add(1)` to cap at `usize::MAX` instead of wrapping,
then `.min(i64::MAX as usize)` to ensure the value fits in SQLite's
signed 64-bit LIMIT parameter.
Includes regression tests that verify `usize::MAX` limit returns results.

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.
