fix(#2150): line-anchor + word-boundary the UI hint regex (review L1/L2)

Browse Source 
Review found the hint value (yes|no) matched prefixes ('nope'/'not' read as
'no') and the hint regex was unanchored, so a mid-line prose mention like 'see
**UI hint**: no above' was treated as the authoritative metadata line. Line-
anchor (^ + m flag) so only a real hint line counts; word-boundary on the value
so nope/not do not mean no. Adds coverage for hint:yes over a pure-backend body
and the nope fall-through.
