hamza.khyari 06428a5db6 feat(plan): implement git worktree sandbox for execute and merge-based apply
Replace flat shutil.copy2 apply with spec-aligned git worktree flow
(specification.md §13225-13276):

Execute phase: creates an isolated git worktree via GitWorktreeSandbox
for the plan's linked git-checkout resource.  LLM file output is
written to the worktree and committed on branch
cleveragents/plan-<plan_id> — no merge yet.

Apply phase: merges the worktree branch into the project's current
branch via git merge.  Prints spec-aligned panels:
  - Apply Summary: Plan ID, artifacts count, insertions/deletions,
    project name, applied-at timestamp
  - Sandbox Cleanup: worktree removed, branch merged to main
  - Footer: ✓ OK Changes applied

Non-git projects (fs-directory resources) fall back to the original
flat directory sandbox with shutil.copy2.

Also fixes:
- context_tier_hydrator metadata types (int/float → string) that
  caused Pydantic validation errors during context assembly
- A2A facade duplicate execute dispatch (idempotent handler)
- Logs actual error from context assembly failures
