fix(web): exclude brackets from CJK autolink punctuation stripping (#486)

* fix(web): exclude brackets from CJK autolink punctuation stripping

Fullwidth brackets and parentheses (（）【】「」etc.) can appear in
valid URL paths, so they should not be stripped. Narrow the regex to
only sentence-ending punctuation: comma, period, semicolon, colon,
exclamation, question mark.

* fix(web): always show 'Agent launched' for internal metadata results

The tool state is set to 'completed' immediately when the result
arrives, so the state-based label was always showing 'Done' for
internal launch metadata. Remove the state check and always show
'Agent launched'.

* fix(web): handle sentence-ending punctuation followed by closing brackets

The regex was missing cases like 。） where a sentence-ender is followed
by a closing bracket. Use a pattern that matches sentence-ending
punctuation optionally followed by trailing closing brackets/parens.
A bare closing bracket without a preceding sentence-ender is still
preserved as a valid URL character.
