[codex] Add E2E workflow profiles

[mashbean]

Summary

• Extend the Test E2E workflow with manual target_env and test_profile inputs.
• Keep the existing Vercel preview webhook path compatible through vercel_preview_url, pr_number, and pr_sha.
• Resolve default URLs for preview, matters.icu staging, and matters.town production.
• Block production E2E runs unless test_profile=prod-smoke or production_mutation_approved=true.
• Update docs/e2e-release-evaluation.md with the new workflow dispatch inputs.

Validation

• prettier --check .github/workflows/test_e2e.yml docs/e2e-release-evaluation.md
• ruby -e "require 'yaml'; YAML.load_file('.github/workflows/test_e2e.yml'); puts 'workflow yaml ok'"
• git diff --check
• Local resolver simulation:
  • preview/default -> npm run test:e2e
  • staging/mutation -> npm run test:e2e:mutation
  • production/prod-smoke -> npm run test:e2e:prod-smoke
  • production/default without approval -> blocked

Notes

This PR changes workflow dispatch behavior only. It does not run live E2E against preview, matters.icu, or matters.town.
