[BUG] git commit fails when no default editor is available in image

[c-vigo]

Description

git commit fails in the devcontainer when no text editor is installed/configured as the default editor.

Steps to Reproduce

1. Start a shell in the devcontainer image.
2. Ensure no default editor is available/configured (e.g., no EDITOR/VISUAL set and no editor binary present).
3. Run git commit without -m.
4. Observe failure with an editor-related error.

Expected Behavior

git commit should have a usable editor path in the image, or fail with clear guidance on how to configure one.

Actual Behavior

Commit fails because Git cannot open an editor (no text editor is available in the image (or no default)), so the commit cannot proceed without -m.

Environment

• OS: linux 6.17.0-19-generic
• Shell: bash
• Workspace: /home/carlosvigo/Documents/vigOS/devcontainer
• Container Runtime: unknown
• Image Version/Tag: unknown
• Architecture: unknown

Additional Context

This blocks normal interactive commit flow and can surprise contributors expecting default Git behavior.

Possible Solution

Install/configure a default terminal editor in the image (or set core.editor/EDITOR), and document the fallback behavior in contributor docs.

Acceptance Criteria
