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.

Change the `who` command's --limit flag from default=20 to optional,
so omitting it returns all results. This matches the behavior users
expect when they want a complete expert/workload/active/overlap listing
without an arbitrary cap.
Also applies clippy-recommended sort improvements:
- who/reviews: sort_by(|a,b| b.count.cmp(&a.count)) -> sort_by_key with Reverse
- drift: same pattern for frequency sorting
Adds Theme::color_icon() helper to DRY the stage-icon coloring pattern
used in sync output (was inline closure, now shared method).
Workload and active modes now exclude discussions on closed issues and
merged/closed MRs by default. Adds --include-closed flag to restore
the previous behavior when needed.

Move inline #[cfg(test)] mod tests { ... } blocks from 22 source files
into dedicated _tests.rs companion files, wired via:
#[cfg(test)]
#[path = "module_tests.rs"]
mod tests;
This keeps implementation-focused source files leaner and more scannable
while preserving full access to private items through `use super::*;`.
Modules extracted:
core: db, note_parser, payloads, project, references, sync_run,
timeline_collect, timeline_expand, timeline_seed
cli: list (55 tests), who (75 tests)
documents: extractor (43 tests), regenerator
embedding: change_detector, chunking
gitlab: graphql (wiremock async tests), transformers/issue
ingestion: dirty_tracker, discussions, issues, mr_diffs
Also adds conflicts_with("explain_score") to the --detail flag in the
who command to prevent mutually exclusive flags from being combined.
All 629 unit tests pass. No behavior changes.
