* Ensures DSM GUI refreshes its updates
* Removed whale icon and changed verbosity
* Added addon for Prometheus+node_exporter
* Changed local image check to check on image ID rather than name
* Update podcheck.sh
changed docker->podman, typo
* - **v0.6.0**:
- **Grafana & Prometheus Integration:**
- Added a detailed Prometheus metrics exporter that now reports not only the number of containers with updates, no-updates, and errors, but also the total number of containers checked, the duration of the update check, and the epoch timestamp of the last check.
- Enhanced documentation with instructions on integrating these metrics with Grafana for visual monitoring.
- **Improved Error Handling & Code Refactoring:**
- Introduced `set -euo pipefail` and local variable scoping within functions to improve reliability and prevent unexpected behaviour.
- Standardised container name handling and refined the Quadlet detection logic.
- **Self-Update Enhancements:**
- Updated the self-update mechanism to support both Git-based and HTTP-based updates, with an automatic restart that preserves the original arguments.
- **Miscellaneous Improvements:**
- Enhanced dependency installer to support both package manager and static binary installations for `jq` and `regctl`.
- General code refactoring across the project for better readability and maintainability.
* Update podcheck.sh
* increment version
* Update Quadlet detection logic
Update Quadlet detection logic to support flexible service naming
- Modified the quadlet update block to first try an exact match for "$i.service".
- If no exact match is found, build a regex pattern from the container name (allowing underscores and hyphens interchangeably) and search user service units.
- When multiple candidate units are found, the script attempts to choose the one that exactly matches (ignoring case) or defaults to the first candidate.
- This update allows containers like "containera" to match service units named "container_a.service" and supports scenarios with multiple counterparts (e.g., matrix-a, matrix-b, matrix_db).
* search name fix
* fixes to arg parsing
* Logic overhaul, verbose output and better syntax
* Added support for prometheus
