fix(integrations): address PR #465 review — CI Go version, GORM history limit, error callback

- CI workflow: bump go-version from 1.23 to 1.26 to match project requirements
- GORM plugin: add maxHistory field (default 1000) to bound query record growth
- GORM plugin: add OnParseError callback for visibility into parse failures
- GORM plugin: add NewPluginWithOptions constructor with PluginOptions struct
- Tests: add coverage for MaxHistory trimming, OnParseError callback, defaults
