feat(tui): add soak + pagination race tests (bd-14hv)
7 soak tests: 50k-event sustained load, watchdog timeout, render interleaving, screen cycling, mode oscillation, depth bounds, multi-seed. 7 pagination race tests: concurrent read/write with snapshot fence, multi-reader, within-fence writes, stress 1000 iterations.

//! Concurrent pagination/write race tests (bd-14hv).
|
||||
//!
|
||||
//! Proves that the keyset pagination + snapshot fence mechanism prevents
|
||||
//! duplicate or skipped rows when a writer inserts new issues concurrently
|
||||
//! with a reader paginating through the issue list.
|
||||
//!
|
||||
//! Architecture:
|
||||
//! - DbManager (3 readers + 1 writer) with WAL mode
|
||||
//! - Reader threads: paginate using `fetch_issue_list()` with keyset cursor
|
||||
//! - Writer thread: INSERT new issues concurrently
|
||||
//! - Assertions: no duplicate IIDs, snapshot fence excludes new writes
