fix: remove Cirrus CI persistent worker integration

[deekay2310]

Summary

Closes #859.

Cirrus CI shut down on June 1, 2026 when Cirrus Labs joined OpenAI. This PR removes all dead Cirrus CI persistent worker code from the codebase:

• pkg/integrations/cirrus/ — deleted entirely (Go package, shell/ps1 setup snippets)
• CLI flags — --it-cirrus-pw-token and --it-cirrus-pw-labels removed from all 8 command files (AWS rhel/fedora/windows/mac-pool, Azure rhel/windows, IBM power/z) and from params.go
• Security groups — port 3010 ingress rules removed from AWS fedora, EKS, and mac machine modules
• Context — CirrusPWArgs field removed from ContextArgs and integration init
• Cloud-config templates — Cirrus blocks removed from rhel (base + snc) and fedora cloud-config files
• Bootstrap scripts — Cirrus blocks removed from Windows bootstrap.ps1, Azure rhqp-ci-setup.ps1 (including $cirrusToken param), and Mac request.sh
• Azure Windows — cirrusToken removed from powershell command format strings
• Docs — Cirrus line removed from README integrations list, flag docs removed from ibm-power.md and ibm-z.md
• Stale TODO — removed an outdated TODO comment in mac-pool.go that listed cirrus-persistent-worker as a future integration mode; this design direction was superseded by the current context-args pattern where integrations are selected via GHRunnerArgs/GLRunnerArgs fields

35 files changed, 437 lines removed. No functional changes to remaining integrations (GitHub Actions, GitLab Runner).

Test plan

• go build ./... passes — pure dead-code removal, no logic changes to remaining integrations
