Add -u (--image-upload-command) and -d (--image-delete-command) flags to allow using external CLI tools for image upload and deletion instead of Google Drive. The external CLI receives image data via stdin and environment variables: - DECK_UPLOAD_MIME: MIME type of the image - DECK_UPLOAD_FILENAME: suggested filename - DECK_DELETE_ID: resource ID to delete The upload command should output: - Line 1: public URL of the uploaded image - Line 2: resource ID for later deletion This enables integration with custom storage backends like GCS, S3, or any other service via CLI wrappers, similar to how laminate works for code block to image conversion. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add support for CEL template expressions in image upload/delete commands,
similar to how -c (code-block-to-image-command) works.
Upload command (-u) supports:
- {{mime}} - MIME type of the image
- {{filename}} - suggested filename
- {{env.XXX}} - environment variables
Delete command (-d) supports:
- {{id}} - resource ID to delete
- {{env.XXX}} - environment variables
Implementation:
- Extract template expansion logic into new `template` package
- Move tests from md/template_test.go to template/template_test.go
- Update md and deck packages to use the shared template package

The filename is not used by external uploaders like reprint-gcs, which generate their own object IDs using UUIDs. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
