Multi-line bash commands (e.g., for loops with newlines) were being passed
as single "lines" to renderOutputBlock. Since visibleWidth() treats newlines
as width 0, truncateToWidth() calculated incorrect truncation points. The
result was rendered lines with embedded newlines that exceeded terminal width,
causing "Rendered line N exceeds terminal width" crashes.
Split section lines by newlines before processing so each line gets properly
truncated and wrapped with box borders.

- Updated release script to properly handle Rust workspace version updates in Cargo.toml files and regenerate lockfiles.
The nullish coalescing operator (??) was treating null as a fallback
trigger, causing getAskTimeout()'s null return value (meaning 'disabled')
to be replaced with DEFAULT_ASK_TIMEOUT_MS (30000ms).

- undefined: settingsManager unavailable → use default
- null: user explicitly disabled timeout → preserve null
- number: user-set timeout → use that value
