fix(skills-hub): stop ellipsis-truncating the Identifier column (#33810)

`hermes skills search` rendered the Identifier column with the default
overflow behaviour, so long slugs (notably browse-sh — every browse-sh
skill ends in a `-XXXXXX` hash that's part of the identifier) were cut
to `browse-sh/weathe…`. Users copied the visible string into
`hermes skills install` and got a not-found error because the hash was
gone.

Set overflow="fold" on the Identifier column in both search tables
(`do_search` and the `_resolve_short_name` multi-match table) so long
slugs wrap onto a second line instead of getting eaten. Also add a
`--json` flag to `hermes skills search` (and the `/skills search`
slash variant) for scripting — emits a list of {name, identifier,
source, trust_level, description} objects with the full identifier,
which is the right shape for copy-paste pipelines too.

Closes #33674.
