- Apply replaceTabs to all text rendering paths in task tool (output,
task section, context, review explanations, finding bodies)

shared context duplicated across every task
todo_write renderResult used truncateToWidth with Ellipsis.Omit which
silently drops content, and the empty-todos fallback returned a raw
component that bypassed width handling entirely. Switched all paths
to return Text(text, 0, 0) which applies wrapTextWithAnsi at render
time, preserving full todo content on narrow terminals.
Ask tool renderResult returned raw line arrays that bypassed the Text
component's word wrapping, causing a TUI crash when user input exceeded
terminal width. Switched all renderResult code paths to return
Text(text, 0, 0) which applies wrapTextWithAnsi at render time.
