Fix approved pr-agent-context refresh runs

[shaypal5]

Summary

Fixes the pr-agent-context refresh path used after Copilot or other bot-authored reviews land on an open PR.

This specifically addresses the manual Approve Run regression seen on PR #25: GitHub did create a second attempt after approval, but the refresh workflow failed at reusable-workflow validation with startup_failure before any job existed.

The refresh workflow already had direct review triggers and a scheduled dispatcher, but the workflow call still passed the old pull_request_* input names into shaypal5/pr-agent-context/.github/workflows/pr-agent-context.yml@v4. The reusable workflow expects the *_override inputs, so manually approved bot-triggered refresh attempts could fail at workflow startup before any job existed.

Changes

• Pass pull_request_number_override, pull_request_head_sha_override, and pull_request_base_sha_override to the reusable pr-agent-context workflow.
• Add trigger_event_name and trigger_event_action dispatch inputs, then forward them as trigger metadata overrides.
• Make scheduled workflow_dispatch refreshes non-cancelling so fallback dispatches do not churn in-flight runs.
• Add a run-name that makes scheduled/manual refresh runs easy to dedupe and inspect.
• Set coverage_source_workflows: CI for cross-run coverage lookup.
• Send schedule trigger metadata from the dispatcher.
• Update .agent-plan.md with the expected post-merge state.

Validation

• python YAML parse of both refresh workflow files passed.
• git diff --check passed.
• Commit hooks passed: trim trailing whitespace, end-of-file fixer, YAML check, merge-conflict check.

Notes

actionlint is not installed in the local environment, so validation used YAML parsing and the repository pre-commit YAML check.

Pull request overview

Fixes the pr-agent-context refresh fallback path by aligning the caller workflow inputs with the reusable shaypal5/pr-agent-context workflow’s expected *_override parameters, and by improving refresh dispatch metadata/concurrency behavior so bot-authored review refreshes reliably start.

Changes:

• Update refresh workflow to pass pull_request_*_override inputs and forward synthetic trigger metadata.
• Adjust refresh concurrency so workflow_dispatch fallback runs do not cancel in-flight runs; add a more informative run-name.
• Update scheduled dispatcher to send schedule trigger metadata and update .agent-plan.md status text.
