Auto Changelog & Release / release (push) Successful in 7s
refactor: remove config.env and integrate settings into scripts
- Deleted `config.env` as all values are now directly integrated into the scripts.
- Updated `scripts/generate-changelog.sh` to replace remaining `echo` commands with `log_info` and `log_error`.
- Ensured all scripts are self-contained and consistent in their logging and configuration handling.

# generate-changelog.sh – generates a Debian-style changelog via git-cliff
#
# Usage:
# ./generate-changelog.sh -c cliff.debian.toml -t v2.9.1 -o debian/changelog
#
# Options:
# -c, --config <file> Path to a valid git-cliff config file (required)
# -t, --tag <tag> Git tag used as the starting point for the changelog (required)
# -o, --out <file> Target changelog file to write to (required, unless --debug)
# -d, --debug Print changelog to stdout instead of writing the file
# -h, --help Show this help message
#
# Behaviour:
# • Verifies git-cliff, sed, and git are installed.
# • Checks that the config file exists and is readable.
# • Ensures the parent directory of the output file exists (unless --debug).
# • Generates the changelog; removes a leading empty line.
