Add skip-if-no-match field support as inverse of skip-if-match

[Copilot]

Adds skip-if-no-match field to the on: section that skips workflow execution when a GitHub search query returns no matches (or fewer than minimum required). This is the inverse of skip-if-match which skips when matches exist.

Changes

Schema & Types

• Added skip-if-no-match to workflow schema supporting both string format (implies min: 1) and object format with explicit min threshold
• Added SkipIfNoMatchConfig struct and SkipIfNoMatch field to WorkflowData
• Added constants: CheckSkipIfNoMatchStepID, SkipNoMatchCheckOkOutput

Compiler Integration

• Created check_skip_if_no_match.cjs handler that validates minimum match count via GitHub search API
• Updated buildPreActivationJob() to generate skip-if-no-match check step when configured
• Updated activation condition logic to include skip_no_match_check_ok output
• Added extraction/processing functions in stop_after.go

Documentation

• Added skip-if-no-match section to triggers.md with usage examples and common patterns

Applied to issue-monster Workflow

• Added skip-if-no-match: "is:issue is:open" to the issue-monster workflow to prevent unnecessary runs when there are no open issues to process

Usage

# Wait for deployment PRs before running
on:
  schedule:
    - cron: "0 */2 * * *"
  skip-if-no-match: "is:pr is:open label:ready-to-deploy"

# Require minimum threshold
on:
  workflow_dispatch:
  skip-if-no-match:
    query: "is:issue is:open label:needs-review"
    min: 5

# Combine with skip-if-match for complex conditions
on:
  workflow_dispatch:
  skip-if-match: "is:issue is:open label:blocker"
  skip-if-no-match: "is:pr is:open label:ready"

Testing

Added comprehensive test suite covering string format, object format, combined checks, and edge cases. All tests passing.

Original prompt

Add a "skip-if-no-match" field support in the "on" section that works as opposite to the "skip-if-match" field.

Added skip-if-no-match to issue-monster workflow in commit 637f0e8. The workflow now includes:

skip-if-no-match: "is:issue is:open"

This prevents the workflow from running when there are no open issues in the repository, saving CI resources. The workflow will now skip execution if:

1. There are 9+ draft PRs from Copilot (skip-if-match condition)
2. There are NO open issues to process (skip-if-no-match condition)
