Subject: [PATCH 1/2] feat(cli): add 'feast projects delete' command (issue
 #5095)

Exposes project deletion via the CLI. The new `feast projects delete <name>`
command calls `store._registry.delete_project()` which is already implemented
in all concrete registries. Adds an interactive confirmation prompt that can
be bypassed with --yes/-y for scripted workflows.

- Adds type guard (`assert store._registry is not None`) for mypy.
- Catches both FeastObjectNotFoundException and ProjectNotFoundException so
  the CLI exits cleanly (exit code 1) for either variant raised by concrete
  registry implementations.

Squashed history: this commit consolidates the previous unsigned commits on
the branch into a single DCO-signed commit, per DCO requirements.

Subject: [PATCH 2/2] fix: use store.registry property instead of
 store._registry in project_delete

store._registry is always None until accessed via the lazy-init registry
property. Using store._registry directly caused project_delete to always
crash with an AssertionError.

Fixes: Devin Review finding in feast-dev/feast#6302
