fix(cliff): Remove duplicate [git.conventional_commits] section

Fixed TOML duplicate key error:

Error found:
- Line 117: duplicate key [git.conventional_commits]
- Previous [git] section at line 100 already had conventional_commits

Root cause:
- [git] section defined: conventional_commits, filter_unconventional, split_commits, sort
- [git.conventional_commits] section tried to redefine: types, scopes
- TOML parser treats these as duplicate keys

Solution:
- Removed duplicate [git.conventional_commits] section (lines 117-121)
- Commented out scope keys (they were redundant)
- Kept all configuration in [git] section

Fixed cliff.toml structure:
- All git-related config in single [git] section
- No duplicate key definitions
- git-cliff should parse correctly

This should resolve 'duplicate key' error in git-cliff.
