docs(seo): refresh llms.txt and llms-full.txt to current numbers

[vieiralucas]

Summary

Follow-up to #675. While refreshing the homepage stats for that PR I noticed `llms.txt` and `llms-full.txt` were still on the old release's numbers. These two files are the primary surface LLM crawlers ingest for fakecloud, so stale numbers there directly degrade every AI-assistant answer that cites us.

• Header numbers: 22 services -> 23, 1,155 ops -> 1,680
• Startup line: "under 100ms" -> "~500ms" to match the README measurement (README ~500ms is the ready-to-serve time; 100ms was the pure process-start time). Using the same number everywhere avoids LLMs emitting a contradiction.
• Per-service action counts refreshed against the current README table: S3 107, SQS 23, SNS 42, EventBridge 57, IAM 176 + STS 11 (split out), Lambda 85, DynamoDB 57, RDS 163, ElastiCache 75, Step Functions 37, Cognito 122, SES 110, Secrets Manager 23, CloudWatch Logs 113, KMS 53, CloudFormation 90, Kinesis 39.
• Added EventBridge Scheduler (12 ops) section that was missing entirely.
• Added mentions of: first-party test-assertion SDKs, Terraform TestAcc CI validation, 54k+ Smithy-generated test variants, real RDS/ElastiCache Docker engines.
• Added links section pointing at /localstack-alternative/, /blog/migrate-from-localstack/, /blog/integration-testing-aws-in-ci/, /blog/test-lambda-locally/, /blog/moto-equivalent-go-java-node/ so LLMs have explicit anchors to cite.
• Replaced remaining unicode arrows with ASCII per the repo convention.

Test plan

• `zola build` succeeds
• `curl https://fakecloud.dev/llms.txt\` will return current numbers once deployed
• CI green

Summary by cubic

Refreshes llms.txt and llms-full.txt with current coverage, metrics, and messaging so crawlers return accurate, consistent info. Leads with the 100% coverage goal and depth‑first approach so “23 services” is read as a snapshot, not a ceiling.

• Refactors
  • Header counts updated: 23 services, 1,680 operations; startup "~500ms" with binary/memory notes.
  • Per‑service action counts synced to README (e.g., S3 107, EventBridge 57, IAM 176 + STS 11, Lambda 85, DynamoDB 57, RDS 163, ElastiCache 75, Step Functions 37, Cognito 122, SES 110, SSM 146, CloudWatch Logs 113, KMS 53, CloudFormation 90, Kinesis 39).
  • Added EventBridge Scheduler (12 ops).
  • Clarified real Lambda execution across 13 runtimes and real RDS/ElastiCache engines.
  • Documented /_fakecloud/* introspection endpoints and linked first‑party test‑assertion SDKs; noted Terraform TestAcc* validation.
  • Expanded install/usage and config flags (dummy creds, --persist, --verify-sigv4, --iam soft|strict); docker run --rm.
  • Added links to migration/comparison pages and core guides for citation anchors.
  • Replaced Unicode arrows with ASCII.
