Subgraph-style JS/Postgres indexer example

[truthixify]

Extra labels: example, indexing
Tier: L (5-7 days) | Type: example

Context. Third-party indexer teams keep asking "what's your recommended ingest shape?" Ship a reference: TypeScript indexer that follows Soroban RPC events, writes to Postgres, exposes a GraphQL endpoint. Not production, just canonical shape.

Scope.

• New dir stellar/examples/indexer/ (TypeScript, Fastify, pg, postgraphile).
• Ingest all four contracts' events.
• Reorg-safe: watermark + rollback on chain reorg.
• README with docker compose up one-liner.

Acceptance.

• Runs on futurenet in one command
• Handles a synthetic reorg without corrupting state (test included)
• Doc'd endpoints for name resolution + announcement lookup
