Summary

Implements the HTTP API server for ExploreDNS as described in HAN-389.

Changes

`web/api/server.go`

HTTP server struct with NewServer(addr), Start(), Shutdown(timeout)
CORS middleware (allows all origins, GET/POST/OPTIONS)
Graceful shutdown via context.WithTimeout
net.Listen for immediate port binding (zero-port support for tests)

`web/api/handler.go`

POST /api/traverse — starts async traversal, returns {"id": "uuid", "status": "running"}
GET /api/traverse/{id} — polls status and results
GET /api/traverse/{id}/stream — Server-Sent Events for live progress
GET /api/health — health check
In-memory job store with 1-hour TTL and periodic cleanup
Background traversal via traverse.Traverser with hook-driven SSE fan-out
SPA static file serving with index.html fallback

`web/api/static/index.html`

Placeholder frontend (embedded via //go:embed static)

`cmd/server/main.go`

Runnable server binary with -addr flag and SIGINT/SIGTERM graceful shutdown

`web/api/handler_test.go`

12 tests covering health, CORS, traversal start/poll/stream, SPA fallback

Test results

go vet ./...          ✓
go test -race ./...   ✓ (all packages pass)

- web/api/server.go: HTTP server with CORS middleware, graceful shutdown,
  configurable listen address via NewServer(addr); uses net.Listen so the
  bound port is available via Addr() for tests.

- web/api/handler.go: REST handlers over Go 1.22 mux patterns:
    POST /api/traverse        start async traversal -> {id, status}
    GET  /api/traverse/{id}   poll status + results
    GET  /api/traverse/{id}/stream  SSE live progress events
    GET  /api/health          health check
  In-memory job store with 1-hour TTL and background cleanup goroutine.
  Background traversal via traverse.Traverser with hook-driven progress
  events fanned out to SSE subscribers.

- web/api/static/index.html: placeholder SPA shell (embedded via
  //go:embed static). Unknown URL paths fall back to index.html for
  client-side routing.

- cmd/server/main.go: runnable server binary with -addr flag and
  SIGINT/SIGTERM graceful shutdown.

All tests pass: go test -race ./...  |  go vet ./...
