security: 🛡️ Harden GitHub Actions workflows (#349)
## Summary

This PR addresses several security vulnerabilities and applies hardening
measures to the GitHub Actions workflows:

- **Replace `secrets: inherit` with explicit secret passing** - Prevents
unnecessary exposure of all repository secrets to called workflows
- **Add SHA256 checksum verification for downloaded binaries** -
Protects against supply chain attacks via compromised upstream releases
- **Add GitHub Environment protections for release workflows** -
Requires approval before publishing to Docker Hub or creating releases
- **Add explicit minimal permissions to all workflows** - Follows
principle of least privilege, removes unnecessary `packages: write` from
CI.yml

## Changes by Category

### 1. Explicit Secret Passing
| Workflow | Before | After |
|----------|--------|-------|
| CI.yml → docker-build-ci | `secrets: inherit` | No secrets
(GITHUB_TOKEN is automatic) |
| CI.yml → docker-build-release | `secrets: inherit` | Explicit
`DOCKERHUB_USERNAME`, `DOCKERHUB_TOKEN` |
| CI.yml → e2e-tests | `secrets: inherit` | No secrets (GITHUB_TOKEN is
automatic) |

### 2. Binary Checksum Verification
| Workflow | Binary | SHA256 |
|----------|--------|--------|
| task-rust-lint.yml | taplo 0.8.1 | `c62baa73c9d7c1572...` |
| task-e2e.yml | kurtosis 1.11.99 | `5e88e98c1b255362...` |

### 3. Environment Protections
| Workflow | Job | Environment |
|----------|-----|-------------|
| task-docker-release.yml | build-test-push | `production` |
| task-publish-binary.yml | publish-draft-release | `releases` |
| task-publish-binary.yml | docker-release-candidate | `production` |
| task-publish-runtime.yml | publish-draft-release | `releases` |

### 4. Explicit Permissions
All 14 workflow files now have explicit `permissions:` blocks with
minimal required access.
