Add bootstrap and worker metadata for zero-discovery campaign initialization

[Copilot]

Implementation Complete: Bootstrap + Planning Model for Campaign Generator/Orchestrator ✅

This PR implements an explicit bootstrap + planning model for campaign generator/orchestrator workflows, addressing all requirements from the problem statement.

✅ All Requirements Met

1. Bootstrap + Planning Model

Requirement: Create/select initial work items when discovery = 0

Solution: Three bootstrap strategies implemented:

• seeder-worker: Dispatch scanner to discover work
• project-todos: Read from Project board Todo column
• manual: Wait for manual work item creation

2. Worker Metadata / Standardized Payload Schema

Requirement: Deterministic worker selection with defined input contracts

Solution:

• WorkerMetadata struct with capabilities, payload schemas, priorities
• WorkerPayloadField defines expected inputs with types and descriptions
• Deterministic selection algorithm: match capabilities → validate schema → select by priority

3. Labeling/Correlation Contract

Requirement: Guarantee worker outputs are discoverable and attributable

Solution:

• WorkerOutputLabeling defines guaranteed labeling format
• Workers use regular labels (not separate tracker-label field)
• Campaign's tracker-label automatically applied by workers
• Deterministic keys in titles: [{key}] {description}
• Metadata fields for Project board tracking

4. Orchestrator Integration

Requirement: Orchestrator uses bootstrap when discovery = 0

Solution:

• Bootstrap template renders Phase 0 instructions
• Orchestrator checks discovery count and follows bootstrap mode
• Payload building from worker metadata schemas
• Worker selection based on capabilities and priority

Implementation Details

Core Changes:

• pkg/campaign/spec.go: Added 8 new types for bootstrap and worker metadata
• pkg/campaign/orchestrator.go: Integrated bootstrap rendering
• pkg/campaign/template.go: Added RenderBootstrapInstructions()
• pkg/campaign/schemas/campaign_spec_schema.json: Extended schema
• .github/aw/bootstrap-agentic-campaign.md: Bootstrap template

Testing:

• 13 unit tests covering all scenarios
• Tests for YAML/JSON serialization
• Validation of payload schemas and output labeling
• All tests passing ✅

Documentation:

• Updated docs/campaign-workers.md with bootstrap guide
• Added comprehensive summary: docs/bootstrap-implementation-summary.md
• Documented worker selection algorithm and contracts

Example Usage

id: security-q1-2025
name: Security Alert Burndown
project-url: https://github.com/orgs/example/projects/1
tracker-label: campaign:security-q1-2025

bootstrap:
  mode: seeder-worker
  seeder-worker:
    workflow-id: security-scanner
    payload:
      severity: high

workers:
  - id: security-scanner
    capabilities: [scan-security-alerts]
    output-labeling:
      labels: [automated-scan]
      key-in-title: true
    idempotency-strategy: issue-title-based
    priority: 5
    
  - id: security-fixer
    capabilities: [fix-security-alerts]
    output-labeling:
      labels: [security, automated]
      key-in-title: true
    idempotency-strategy: pr-title-based
    priority: 10

Migration Path

✅ Backward Compatible: Existing campaigns work without changes
✅ Opt-in: New features are optional
✅ Incremental: Can add bootstrap or workers independently

Ready for review and merge! 🚀

Original prompt

The generator/orchestrator still needs an explicit bootstrap + planning model: a way to create/select initial work items when discovery is 0 (e.g., dispatch a seeder/scanner worker or treat Project “Todo” items as the task queue). It also needs worker metadata / a standardized payload schema so it can deterministically choose which worker to run and with what inputs, plus a guaranteed labeling/correlation contract so worker outputs become discoverable and attributable to the right task/campaign.

@copilot campaigns should use regular labels, not tracker label/ids.

@copilot campaigns should use regular labels, not tracker label/ids.

Updated to use regular labels instead of tracker-label in worker metadata. Workers now use the labels field for additional labels, and the campaign's tracker-label (defined at the campaign level) is automatically applied to all worker outputs.

Changes in commit 967a316:

• Removed tracker-label field from WorkerOutputLabeling struct
• Renamed additional-labels to labels
• Updated JSON schema to make labels optional
• All tests passing ✅

@copilot Remove invalid content entry in campaign docs

Removed invalid content entry. The dependency-upgrade-example.campaign.md file was incorrectly placed in docs/src/content/docs/examples/campaigns/ (Astro content directory). Campaign spec files belong in .github/workflows/, not in the docs content directory.

Fixed in commit ff659c3.
