fix: Complete CI compatibility with self-hosted GitHub runners (#134)

## Summary

This PR resolves all CI failures following the migration to self-hosted
GitHub runners (`DH-Testing` group) by eliminating sudo dependencies and
fixing Docker connectivity issues.

## Key Changes

### 🔧 **Eliminated sudo requirements across all workflows**
- **Setup Environment**: Installed mold linker and system dependencies
in userspace without sudo
- **Tool Installation**: Replaced apt/system package installations with
direct binary downloads:
  - Kurtosis: Direct binary download from GitHub releases (v1.10.3)
  - Taplo: Direct binary installation for Cargo.toml formatting
- cargo-nextest: Using `cargo install` instead of GitHub action
(v0.9.100)
- **Runner Cleanup**: Skipped cleanup-runner action entirely on
self-hosted runners (bare-metal manages disk space externally)

### 🐳 **Fixed Docker connectivity for E2E tests**  
- **Enhanced dockerode configuration** with robust fallback logic for
different socket locations
- **Added DOCKER_HOST environment variable** to E2E workflow for
consistent Docker daemon access
- **Implemented connection testing** with detailed error diagnostics for
troubleshooting
- **Resolves FailedToOpenSocket errors** by supporting multiple socket
paths and connection methods

### 🏷️ **Workflow optimizations**
- **Label-based targeting**: All heavy workloads (Rust builds, E2E
tests) now run on `DH-Testing` runners
- **Dependency management**: Used `install-deps: false` flag instead of
hardcoded runner detection
- **Permission fixes**: Corrected Docker build permissions and GHCR
organization names
