fix: bump candid-extractor 0.1.4 → 0.1.6 (ic0::cost_call support) (#39)

## Summary

Bumps `candid-extractor` from 0.1.4 to 0.1.6 in both the `rust` and
`all` images.

### Problem

candid-extractor 0.1.4 fails to inspect WASM files that import
`ic0::cost_call`, a new IC system API used by ic-cdk ≥ 0.19:

```
Error: unknown import: `ic0::cost_call` has not been defined
```

This causes `icp deploy` to fail at the Candid extraction step (step 3
of 3) for any canister compiled with ic-cdk 0.19+.

### Fix

candid-extractor 0.1.6 adds support for `ic0::cost_call` and the other
new IC system API imports introduced in recent ic-cdk versions.

### Verification

Tested locally by building both image versions and running `icp deploy`
+ full `make test` against a canister using ic-cdk 0.19 +
ic-ledger-types 0.16:

- 0.1.4: ❌ `Error: unknown import: ic0::cost_call has not been defined`
- 0.1.6: ✅ all tests pass

### Release versioning

This is a patch release (`1.0.1`) — pure bug fix, no icp-cli version
change, no API changes.
