ci: skip scheduled and release workflows on forks

[joffeoja]

Description

Prevent GitHub Actions workflows that rely on repository secrets or publishing permissions from running on forks. A lot of daily/weekly email spam from failed workflows on forks that are missing the secrets...

This change updates multiple workflows so they only run when the repository is continuedev/continue by adding a guard just like in https://github.com/continuedev/continue/blob/main/.github/workflows/cla.yaml#L17-L18:

if: github.repository == 'continuedev/continue'

This ensures that scheduled tasks, release automation, metrics collection, and dependency submission workflows do not run (and fail) on contributor forks, while preserving all existing behavior for the main repository.

Workflows updated include:

• Daily Snyk Agent
• Metrics (issue metrics)
• GitHub dependency graph submission
• Beta Release
• Stable Release
• Package release workflows for:
  • @continuedev/config-yaml
  • @continuedev/fetch
  • @continuedev/llm-info
  • @continuedev/openai-adapters

Fixes #8662.

Tests

• Validated syntax for each updated workflow
• Confirmed that workflows are skipped on forks
• Verified that workflows continue to run normally on continuedev/continue
