Investigate host-path alias mount strategy for container path parity

[UltraBob]

Summary

Investigate whether we can provide a host-path alias inside the DDEV web container so tools can resolve host paths directly, reducing wrapper/path-translation complexity.

Goal

If the host project is at a path like /Users/.../project, evaluate whether the container can reliably expose that same alias path in addition to /var/www/html.

Investigation scope

• At least one working technical approach
• Install/start lifecycle integration points for the add-on
• Sandbox validation with concrete verification commands/results
• Impact on existing shims/wrappers
• Portability/safety constraints and guardrails
• Clear recommendation: adopt, defer, or reject
