Add pulumi-component-architect skill

[Copilot]

This repo's core purpose is Pulumi/AWS infrastructure, but had no skill for designing Pulumi components, stacks, or resource hierarchies. Adds pulumi-component-architect to fill that gap.

Skill (SKILL.md)

• Triggers on phrases like "design a Pulumi component", "how should I structure my stacks", "cross-stack outputs", "Pulumi resource hierarchy"
• 5-step workflow: parse requirements → component hierarchy summary → per-component design spec → TypeScript skeletons → design rationale
• TypeScript skeleton template enforcing project conventions (single quotes, semicolons, 4-space indent, JSDoc, registerOutputs)
• Stack layer reference table (acct-baseline → net-foundation → svc-platform/stateful-data → workload → monitoring)
• Cross-stack reference decision matrix: Pulumi Stack References vs. SSM Parameter Store
• Required tagging strategy (Environment, Stack, Component, ManagedBy, Name)
• Self-review quality checklist before output

Reference: component-patterns.md

Covers VpcComponent, SubnetComponent, SecurityGroupComponent, EcsClusterComponent, AlbComponent, EcsServiceComponent, RdsComponent, S3BucketComponent — each with URN type string, child resource list, outputs, and design notes. Includes IAM execution role / task role patterns and resource naming convention helper.

Reference: stack-patterns.md

Stack topology diagram, layer ownership and deployment frequency guidance, environment differentiation pattern (isPrd flags, per-env config sizing), cross-stack reference implementations, stack lifecycle deploy/destroy ordering, multi-region provider alias pattern, output naming conventions, and a GitHub Actions CI/CD deployment example.

Original prompt

Add pulumi-component-architect skill — design Pulumi components, stacks, and resource hierarchies (core to the repo's main purpose)
