Ali jawwad c1028e5506 fix(extensions): guard non-numeric catalog downloads in search/info rendering (#3710)
* fix(extensions): guard non-numeric catalog downloads in search/info rendering

`specify extension search` and `specify extension info <id>` format a catalog
entry's `downloads` field with the `:,` thousands separator, guarded only by
`is not None`. Catalog payloads are only shape-validated -- individual fields
are never type-checked and `_get_merged_extensions` returns raw catalog dicts
-- so an entry with a non-numeric `downloads` (e.g. the JSON string "1500",
realistic from a community / SPECKIT_CATALOG_URL / project catalog) makes the
`:,` format raise `ValueError: Cannot specify ',' with 's'`, aborting the
whole command with an uncaught traceback.

Group-format `downloads` only when it is actually numeric; otherwise render it
as-is. Numeric values (int/float, incl. bool) format identically, so correct
catalogs are byte-for-byte unchanged. Every other field in these two renderers
is already `str()`-wrapped; this closes the one unguarded field.

* fix(extensions): escape the non-numeric downloads fallback for Rich markup

Address review feedback: the fallback interpolated the untrusted catalog value
straight into a Rich-rendered string, so guarding the ``:,`` ValueError just
traded it for a MarkupError -- a catalog entry with downloads "[/red]foo" still
aborted `extension search`/`info`, and balanced tags could restyle the output.

Wrap the fallback in _escape_markup(str(...)) at both sites, matching how every
other catalog field in these renderers is already escaped. Numeric values keep
the identical ``:,`` branch, so correct catalogs are unchanged.

* fix(extensions): escape 'stars' too, in the same stats string

Follow-up to the downloads escaping: `stars` is the other catalog-controlled
value joined into the same Rich-rendered stats line, and it was still raw --
verified that stars "[/red]x" raises the same MarkupError and aborts
`extension info`/`search`. Hardening one of the two adjacent values would have
left the reported defect reachable through the sibling field.
