[GENERAL] The PR enables the TID ruff rule with ban-relative-imports = "all" and converts relative imports to absolute across 39 files. However, 8 __init__.py files under samcli/commands/ still use relative imports and are not converted:

• samcli/commands/build/__init__.py
• samcli/commands/delete/__init__.py
• samcli/commands/deploy/__init__.py
• samcli/commands/docs/__init__.py
• samcli/commands/logs/__init__.py
• samcli/commands/package/__init__.py
• samcli/commands/publish/__init__.py
• samcli/commands/sync/__init__.py

Each of these contains from .command import cli # noqa. The bare # noqa comment (originally there to suppress F401 for the re-export) silently suppresses the new TID252 violation as well, so the lint won't fail. But this leaves the migration incomplete — the # noqa is now masking a banned pattern rather than just suppressing an unused-import warning.

Consider converting these files to absolute imports too (e.g., from samcli.commands.build.command import cli # noqa: F401) and narrowing the bare # noqa to # noqa: F401 so TID252 is actually enforced everywhere.
