fix(terminal): linear-time link-provider regex; always allow blob workers in CSP

cmdPattern's empty-matchable unbounded arg group backtracked exponentially
on wrapped heredoc/table lines — hovering one froze the tab for minutes.
Non-empty tokens + bounded reps make it O(n); regression test extracts the
shipped patterns and pins timing on the real killer shapes.

worker-src 'self' blob: is now unconditional so terminal-ui's _safeYield
tick worker (throttling escape) isn't CSP-blocked on non-gesture installs.
