[FEATURE] add support for multiple skills at a time (e.g. asm link)

[saidelike]

Problem Statement

Atm you need to add one skill at a time.

asm link ./skill1 -p claude
asm link ./skill2 -p claude
asm link ./skill3 -p claude
...

Proposed Solution

asm link ./skill1 ./skill2 ./skill3 ./skill4 -p claude

Atm if you run the above, it does not even error but just ignores ./skill2 ./skill3 ./skill4

Alternatives Considered

N/A

Use Cases

Adding multiple skills into a new host

Additional Context

It could also be useful to add support for multiple agents with -p like -p codex claude but that could be part of a new issue.

@saidelike you can select multiple skill at a time. suppose you have 3 different skills in skills/ folder:

asm link ./skills/

then it will allow you to link to all skills in that folder.

although, it could be cooler to have option to select which skills to be linked to, similar with installation step.

Yeah there may be lots of skills and I ideally want to link only certain skills, not all of them
