[Feature]: allow wildcard/glob matching for --skill in npx skills add

[evaisse]

Hello, kudos for this great tool 🤩 !

I’d like to request support for wildcard (glob) matching with --skill when installing skills from a private internal repo ( npx skills add ssh://git@gitlab.xxx.com:7999/fwk/ai-tools.git --skill 'core-*' -a codex -y).
Today --skill appears to require exact names, which makes it cumbersome to install a group of related skills.

I maintain several skills that share a prefix (e.g. citools-*). I want to install all of them at once without listing each name manually. (The only alternative way I've found is to group them by folder.)

Proposed Solution

• Accept glob patterns for --skill, e.g. core-*.
• Match against name and displayName (same targets as exact matching).
• Keep * working as “all skills”.

example

npx skills add ssh://git@gitlab.xxx.com:7999/fwk/ai-tools.git
--skill 'core-*'
-a codex -y

Expected result

• All skills with names starting with core- are selected and installed.

Current behavior

• --skill seems to require exact names; core-* is treated as a literal and does not match.

Nice-to-have

• --dry-run or “preview matched skills” output when a glob is used.

Alternatives Considered

• Running --list and passing many --skill flags is workable but error‑prone and noisy for large groups.
• grouping skills in 'topics' folders and use --all flag to install all skills of a given topic

Additional Context

Let me know if you’d like a PR or if there’s a preferred pattern syntax (glob vs regex).
