feat: migrate to ansible-navigator with Red Hat EE

[chadmf]

Closes #167

Summary

Replace local collection installation with ansible-navigator using Red Hat supported Execution Environment registry.redhat.io/ansible-automation-platform-26/ee-supported-rhel9:latest.

Benefits

• Consistency: Same container locally and in AAP production
• Red Hat support: Certified collections in tested combinations
• Zero collection management: No ansible-galaxy install required
• Dev-prod parity: Identical execution environment
• Security: Red Hat scans and patches container images

Changes

New Files

• ansible-navigator.yml — Navigator config with EE image, volume mounts, env passthrough
• scripts/bootstrap.sh — Bootstrap wrapper with validation and token extraction

Updated Files

• ansible.cfg — Removed collections_path, moved Automation Hub token to env var lookup
• CLAUDE.md — Updated prerequisites and bootstrap workflow for navigator
• .gitignore — Exclude navigator artifacts (ansible-navigator.log, playbook-artifacts/)
• CHANGELOG.md — Documented migration

Migration Steps

# 1. Authenticate to Red Hat registry
podman login registry.redhat.io

# 2. Pull EE image
podman pull registry.redhat.io/ansible-automation-platform-26/ee-supported-rhel9:latest

# 3. Install ansible-navigator
pip install ansible-navigator

# 4. Run bootstrap
ansible-navigator run playbooks/bootstrap_dev.yml \
  -i inventories/rhdp-<customer>-<demo>/ \
  --mode stdout

# Or use wrapper script
./scripts/bootstrap.sh rhdp-<customer>-<demo>

Testing

Tested bootstrap workflow with navigator on sample inventory — all modules resolve correctly from pre-installed collections in EE image.
