[ab-advisor] A/B experiment: sub_agent_strategy for agent-persona-explorer

[Copilot]

Implements the sub_agent_strategy A/B experiment campaign for agent-persona-explorer, testing whether consolidating all scenario testing into a single sub-agent call (batch) reduces token costs vs. the current per-scenario invocation approach.

Frontmatter changes

• Adds experiments: sub_agent_strategy block with variants [per_scenario, batch], 50/50 weight, t_test analysis, effective_tokens as primary metric, and guardrails requiring discussion_created == 1 and scenarios_analyzed >= 3
• issue: #aw_campaign placeholder omitted — parses as null in YAML (comment marker), failing the schema's integer constraint; can be added when a campaign issue number exists
• direction: sub-field on guardrail items replaced with the schema-compliant combined threshold: form (e.g. "==1", ">=3")

Phase 3 conditional blocks

{{#if experiments.sub_agent_strategy == 'batch' }}
Invoke the "agentic-workflows" custom agent **once** with all 3-4 selected scenarios...
{{else}}
For each selected scenario, invoke the "agentic-workflows" custom agent tool...
{{/if}}

• batch: single sub-agent call with all scenarios in a structured list; response parsed for per-scenario assessments
• per_scenario ({{else}}): original behavior preserved unchanged
• Shared Important guidelines remain outside the conditional

Lock file

Regenerated via gh aw compile --approve. The --approve was needed because the prior lock referenced docker/build-push-action and docker/setup-buildx-action that are no longer emitted — a pre-existing delta unrelated to this change.

Pull request overview

Implements an A/B experiment (sub_agent_strategy) for agent-persona-explorer to compare per-scenario sub-agent invocations vs. a single batched sub-agent invocation, aiming to reduce token usage while maintaining quality. Also includes regenerated workflow lockfiles reflecting updated generated firewall/model alias configuration.

Changes:

• Adds an experiments.sub_agent_strategy frontmatter block to agent-persona-explorer.md (variants, metrics, guardrails, analysis metadata).
• Adds Phase 3 conditional prompt logic to switch between batch and per_scenario sub-agent invocation strategies.
• Regenerates multiple workflow *.lock.yml files (notably updating the embedded AWF config model alias map).
