feat(aws-observability): Add AWS Observability plugin

[theagenticguy]

Adds a new aws-observability plugin providing a comprehensive AWS observability platform combining CloudWatch Logs, Metrics, Alarms, Application Signals (APM), CloudTrail security auditing, and automated codebase observability gap analysis.

Changes

New plugin: aws-observability (12 files, 4300 lines)

• Plugin manifest (.claude-plugin/plugin.json): name, description, keywords, Apache-2.0 license
• MCP servers (.mcp.json): 4 stdio servers from AWS Labs:
  • awslabs.cloudwatch-mcp-server - CloudWatch Logs, Metrics, Alarms
  • awslabs.cloudwatch-applicationsignals-mcp-server - Application Signals APM, SLOs, tracing
  • awslabs.cloudtrail-mcp-server - CloudTrail security auditing
  • awslabs.aws-documentation-mcp-server - AWS documentation access
• Skill (skills/aws-observability/SKILL.md, ~155 lines): Auto-triggers on observability intent (monitoring, troubleshooting, incident response, log analysis, security audit, etc.) with progressive disclosure via reference file links
• Reference files (8 files in skills/aws-observability/references/):
  • incident-response.md - Incident management workflows with multi-tool correlation
  • log-analysis.md - CloudWatch Logs Insights query patterns and syntax reference
  • alerting-setup.md - Intelligent alarm configurations with AWS best practices
  • performance-monitoring.md - Application Signals APM, SLOs, distributed tracing
  • security-auditing.md - CloudTrail security analysis and compliance
  • observability-gap-analysis.md - Codebase observability audit across 6 languages
  • application-signals-setup.md - Application Signals enablement guide
  • cloudtrail-data-source-selection.md - CloudTrail data source priority strategy
• Marketplace registry (.claude-plugin/marketplace.json): Added aws-observability entry with category observability

Build validation: All checks pass (markdown lint, manifest validation, cross-reference validation, formatting, security scans).

This reference instructs the agent/user to “Check Cost Explorer for usage spikes” and includes “Cost Impact (Cost Explorer)” in the end-to-end workflow, but the plugin’s .mcp.json doesn’t configure a Cost Explorer-related MCP server (and the PR description notes Cost Explorer integration is out of scope). Please either remove/replace these steps with CloudWatch-based cost signals, or explicitly mark them as manual console/CLI checks.
