Given a canister ID or name in $ARGUMENTS, fetch and summarize its Candid interface.

Steps

Resolve the canister ID by running the resolve script from the skill's base directory:
```
./scripts/resolve-canister-id.sh "$ARGUMENTS"
```
If $ARGUMENTS is already a valid principal, the script echoes it back. Otherwise, it queries the IC Dashboard API and outputs matches as <canister-id> <name> (one per line).
- If there is a single result, clearly display the resolved canister ID and use it directly.
- If there are multiple results, present the list to the user and ask them to pick one before continuing.
Fetch the Candid interface using the resolved canister ID:
```
./scripts/fetch-candid.sh <resolved-canister-id>
```
The script outputs the path to the downloaded .did file.
