Merge missing-tools processing into conclusion job

[Copilot]

Consolidates the missing_tool safe output processing into the conclusion job rather than running it as a separate workflow job.

Changes

• notify_comment.go: Add missing-tool step to buildConclusionJob, following the existing noop pattern. Include tools_reported and total_count outputs.
• compiler_jobs.go: Remove buildCreateOutputMissingToolJob call from buildSafeOutputsJobs
• missing_tool.go: Remove unused buildCreateOutputMissingToolJob function
• missing_tool_test.go: Remove job creation tests (now covered by workflow compilation tests)

Result

Before: conclusion job depended on separate missing_tool job
After: conclusion job runs missing-tool step inline (same as noop)

# conclusion job now includes both steps
steps:
  - name: Process No-Op Messages
    id: noop
  - name: Record Missing Tool
    id: missing_tool
outputs:
  noop_message: ${{ steps.noop.outputs.noop_message }}
  tools_reported: ${{ steps.missing_tool.outputs.tools_reported }}
  total_count: ${{ steps.missing_tool.outputs.total_count }}

No permission changes needed—conclusion job already has contents: read.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/user
  • Triggering command: /usr/bin/gh gh api user --jq .login (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Merge the steps of "missing-tools" in the conclusion job, next to the noop steps. Remove missing-jobs job.
Adjust logic to generate conclusion job accordingly.
Adjust permissions for conclusion job accordingly.
