feat: personalization layer (Usage Analysis + My Stuff) — v1.1.0

[tajdars]

v1.1.0 — Personalization layer

Adds an opt-in personalization layer on top of the base dashboard. When enabled, the dashboard offers a My stuff toggle that filters services, APIs, and CloudFormation resources to only what's actually used in your account.

What's new

• Usage Analysis stack (--enable-usage-analysis): a new opt-in CloudFormation stack with a Step Functions state machine that orchestrates two analyzers (CloudTrail + CloudFormation) and a decorator. Output is written back to the website bucket as personalized data files.
• Settings page: new "Run usage analysis" button that triggers analysis on demand and polls for completion.
• Capability by Region page: new "My stuff" toggle in the page header. Active CloudFormation tab gains a Stack filter for resource types in use.
• Auto-discovery: deploy script auto-discovers the CloudTrail bucket from describe-trails if --cloudtrail-bucket is omitted.
• Lake Formation bootstrap: stack provisions cleanly on a fresh account by adding the analyzer role and the deployer role as Data Lake Admins (preserves any pre-existing admins).

Architecture

Component	Purpose
Step Functions State Machine	Runs two analyzers in parallel, then the decorator
CloudTrail Analyzer Lambda	Athena queries over CloudTrail logs
CloudFormation Analyzer Lambda	Inspects active CloudFormation stacks
Usage Decorator Lambda	Joins analyzer output with the master catalog
Glue Database / Table + LF Permissions	Schema over the CloudTrail bucket for Athena
EventBridge Rule	Daily scheduled runs (configurable)

Versions

• package.json (root + source/constructs, source/lambda, source/shared) bumped to 1.1.0.

Testing

• 83/83 lambda unit tests + 11/11 constructs unit tests passing.
• End-to-end verified on two fresh accounts: bootstrap CR ran, auto-discovery picked the right CloudTrail bucket, full analysis run produced personalized data, and the My stuff toggle / Stack filter rendered with non-zero counts.
