- Rename `ui_scroll_tick_count: u64` → `should_text_scroll: bool` across all 33
call sites; `on_ui_scroll_tick` now assigns true/false instead of 0/1
- Remove two now-redundant comments from `test_on_ui_scroll_tick`
- Move `WHITESPACE_RE` static declaration below module imports in network/mod.rs
- Remove `MANAGARR_TICK_RATE_MS` env var and its parsing helpers; `recv()`-based
blocking already brings idle CPU to near-0, and tuning tick rate silently
stretches the poll cadence — keep `DEFAULT_TICK_RATE_MS` const only
