Split safe-output handler registry by category

[Copilot]

The 1,091-line safe-output handler registry combined 50 inline handlers in one map, making reviews and concurrent changes unnecessarily difficult.

• Registry organization

  • Split handlers into focused issue/discussion, pull request, automation, dispatch/reporting, and artifact/project registries.
  • Moved shared token resolution into a dedicated file.
  • Reduced the original registry file to category assembly.

• Regression coverage

  • Verify all 50 handler keys are assembled exactly once.
  • Detect missing, duplicated, or unexpected registrations.

• Fixes [deep-report] Split pkg/workflow/safe_outputs_handler_registry.go (1,091 lines, 49-entry closure map) by handler category #55470

Merged main and resolved conflicts — main had already merged an equivalent registry split (#55482) for the same underlying issue, so this branch now adopts main's version of the affected files and drops the redundant duplicate files this branch had added. Local make fmt/make lint/make test-unit pass (3 pre-existing lint warnings confirmed present on main itself, unrelated). See 7db22d6.
