### Link to Issue or Description of Change
**1. Link to an existing issue (if applicable):**
- Closes: #3961
**Problem:**
Excessive notifications from periodic workflow runs (every 6 hours for triage, daily for stale-bot and docs upload) in forks where they are not needed.
**Solution:**
Add repository checks to prevent scheduled workflows from running in forked repositories.
The workflows will now only run in the main google/adk-python repository.
### Testing Plan
I think that unit tests and E2E are not needed because this change is for GitHub Actions (not ADK source code).
_Please describe the tests that you ran to verify your changes. This is required
for all PRs that are not small documentation or typo fixes._
**Unit Tests:**
- [ ] I have added or updated unit tests for my change.
- [ ] All unit tests pass locally.
_Please include a summary of passed `pytest` results._
**Manual End-to-End (E2E) Tests:**
_Please provide instructions on how to manually test your changes, including any
necessary setup or configuration. Please provide logs or screenshots to help
reviewers better understand the fix._
