Refactor safe-output repo target accessors

[Copilot]

Safe-output schema generation repeated AllowedRepos and TargetRepoSlug extraction across a large tool-name switch, making new tool support easy to implement inconsistently.

• Registry-based targeting

  • Replaced the switch with a tool-name-to-accessor registry.
  • Centralized repo-parameter eligibility and description generation.

  accessor := repoTargetAccessors[toolName]
  targetConfig := accessor(safeOutputs)

• Coverage guard

  • Added a focused test that verifies the registry contains exactly the supported repo-target tools.

• Fixes [duplicate-code] Refactor repeated repo-target extraction in safe output tool schema generation #53836
