[plan] Split `compiler_safe_outputs_config.go` by handler group

[github-actions]

Objective

Split pkg/workflow/compiler_safe_outputs_config.go (1,035 lines) into focused files by separating builder infrastructure from handler implementations.

Context

Discussion: #26221

This file generates the GH_AW_SAFE_OUTPUTS_HANDLER_CONFIG env variable consumed by the JavaScript safe-outputs runner. It mixes builder infrastructure, individual handler config functions, and the top-level orchestrator.

Approach

1. Move the handlerConfigBuilder struct and all its methods to compiler_safe_outputs_builder.go
2. Move individual handler config generator functions (issues, PRs, comments, discussions, etc.) to compiler_safe_outputs_handlers.go
3. Keep the top-level orchestrator and GenerateSafeOutputsHandlerConfig in the original file

Files to Modify

• Split: pkg/workflow/compiler_safe_outputs_config.go
• Create: pkg/workflow/compiler_safe_outputs_builder.go
• Create: pkg/workflow/compiler_safe_outputs_handlers.go

Acceptance Criteria

• Original compiler_safe_outputs_config.go is ≤ 300 lines
• Each new file is ≤ 300 lines
• make build && make test-unit pass without errors
• make fmt && make lint pass without errors
