feat: add real-time conventional commit linting

[rm-hull]

Integrated go-conventionalcommits to provide instant feedback in the commit view. The UI now validates the message structure against conventional commit standards and checks for line length constraints (50 characters for subject, 72 for body).

Fixes #104

Code Review

This pull request implements commit message linting using the go-conventionalcommits library, enforcing length constraints on subject and body lines within the UI. Feedback highlights a critical syntax error in the uintPtr function and a potential runtime panic in the border rendering logic due to unchecked padding calculations. Recommendations were also made to use character width instead of byte length for validation and to improve the robustness of error parsing from the linting library.
