Stabilize Daily Agent of the Day sub-agent model routing for Copilot chat endpoint compatibility

[Copilot]

The Daily Agent of the Day Blog Writer workflow was intermittently failing when sub-agent calls resolved to mai-code-1-flash-picker, which is not accessible via the /chat/completions path used in this execution flow. This change constrains sub-agent model selection to explicit chat-compatible models to prevent that failure mode.

• Model pinning for inline sub-agents

  • Updated inline agent model declarations in .github/workflows/daily-agent-of-the-day-blog-writer.md:
    • persona-generator: mai-code → claude-haiku-4.5
    • story-writer: large → claude-sonnet-4.6
    • seo-optimizer: mai-code → claude-haiku-4.5

• Prompt-level execution guardrail

  • Added explicit instruction in the workflow process section to pass compatible models on task sub-agent invocations, so runtime calls don’t drift to incompatible defaults.

• Compiled workflow sync

  • Regenerated workflow lock outputs to keep markdown source and compiled workflow artifacts aligned with the updated model configuration.

@copilot fix models.json to use the correct endpoint for this model

Implemented in commit 7055cf8.

• Added mai-code to both model catalogs with wire_api: "responses" so it routes to the correct endpoint.
• Kept catalog mirrors synchronized:
  • /home/runner/work/gh-aw/gh-aw/actions/setup/js/models.json
  • /home/runner/work/gh-aw/gh-aw/pkg/cli/data/models.json
• Added a targeted test in /home/runner/work/gh-aw/gh-aw/actions/setup/js/copilot_harness.test.cjs to assert COPILOT_MODEL=mai-code auto-configures COPILOT_PROVIDER_WIRE_API=responses.

Addressed in 4c8b08b: removed mai-code as a standalone entry from both models catalogs and kept only mai-code-1-flash-picker for wire API routing/tests.
