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.
