feat: Vendor pezkuwi-subxt and pezkuwi-zombienet-sdk into monorepo

- Add pezkuwi-subxt crates to vendor/pezkuwi-subxt
- Add pezkuwi-zombienet-sdk crates to vendor/pezkuwi-zombienet-sdk
- Convert git dependencies to path dependencies
- Add vendor crates to workspace members
- Remove test/example crates from vendor (not needed for SDK)
- Fix feature propagation issues detected by zepter
- Fix workspace inheritance for internal dependencies
- All 606 crates now in workspace
- All 6919 internal dependency links verified correct
- No git dependencies remaining
