Remove the conditional retry logic and always run the venv creation, pip install of calibreweb, and uv sync without build isolation. Updated ct/calibre-web.sh and install/calibre-web-install.sh to: run `$STD uv venv`, `$STD uv pip install --python /opt/calibre-web/.venv/bin/python --no-cache-dir calibreweb`, then `$STD uv sync --no-dev --no-build-isolation`. This simplifies the dependency installation flow and ensures the virtualenv and package are installed before syncing.
Add retry logic to ct/calibre-web.sh and install/calibre-web-install.sh: if 'uv sync --no-dev' fails, the scripts now create/ensure a venv, install the 'calibreweb' package into it via 'uv pip', and retry 'uv sync' with '--no-build-isolation'. This works around failures caused by isolated builds or build-step issues and preserves existing log messages.
Replace pushd/popd directory stack usage with plain cd in ct/gramps-web.sh and install/gramps-web-install.sh, and remove the >/dev/null redirections. The frontend build and backend migration steps remain functionally the same but use simpler directory changes to avoid relying on pushd/popd output suppression.
Replace plain cd with pushd/popd (silenced) when building the frontend and running migrations to preserve the original working directory. Ensure database migrations run from /opt/gramps-web-api and export ALEMBIC_CONFIG in both install and update scripts so Alembic uses the correct config. Minor cleanup to silence directory stack output.
Replace legacy container/install scripts with a single tools/addon/cronmaster.sh addon. The new script consolidates install, update and uninstall flows, uses community-scripts core functions, fetches prebuilt GitHub releases, sets up Node.js (defaults to v22), creates a systemd service and an update helper (/usr/local/bin/update_cronmaster). Removed ct/cronmaster.sh and install/cronmaster-install.sh to avoid duplication and centralize maintenance.
Use an absolute path for the downloaded edgetpu model to ensure it lands at /edgetpu_model.tflite. Wrap the OpenVINO build step in a conditional: only copy the generated .xml/.bin and fetch the COCO class file if build_ov_model.py exits successfully; otherwise emit a warning and allow Frigate to fall back to the CPU model (handles machines without required CPU instructions).
