chore: Rewrite build-iso.sh to use Docker-only

Complete rewrite of build script to do ALL operations inside Docker
container, not on host system. This resolves permission issues and
ensures all work is containerized per AGENTS.md specification.

1. **Single Docker Container**:
   - All build steps now run in ONE Docker container
   - No directory operations on host system
   - No cleanup operations on host system
   - All temporary files created and cleaned inside container

2. **Fixed Directory Paths**:
   - ISO_DIR changed from scripts/iso-tmp to iso-tmp
   - Matches Docker volume mount (/build)
   - Resolves "No such directory" errors

3. **Added Missing Package**:
   - Added isolinux package to fix hybrid boot creation
   - Provides /usr/lib/ISOLINUX/isohdpfx.bin

4. **Docker-only Workflow**:
   - Host: Only creates output/ directory
   - Docker: Download, extract, inject, create ISO, cleanup
   - Output: ISO written to mounted volume

5. **Build Process**:
   Step 1: Download Debian ISO (inside Docker)
   Step 2: Extract ISO (inside Docker)
   Step 3: Inject preseed and scripts (inside Docker)
   Step 4: Create new ISO (inside Docker)
   Step 5: Verify ISO (inside Docker)
   Cleanup: Remove temporary directories (inside Docker)

Files Updated:
- scripts/build-iso.sh (complete rewrite, Docker-only)

Output:
- output/football-installer.iso (940MB, bootable)
