The CI was consistently failing because go.mod declared 'go 1.25.6',
which triggered Go's GOTOOLCHAIN=auto mechanism to auto-download Go
1.25.6 on the CI runner. That pre-release build lacks the 'covdata'
tool, causing 'go test -race -coverprofile=coverage.out ./...' to exit
non-zero on cmd/ packages (which have no test files), even though all
actual tests passed.
Fix:
- Lower go directive from 1.25.6 to 1.24.0 (minimum required by deps)
- Set go-version: '1.24' in setup-go to match
- Add GOTOOLCHAIN=local to every go command in ci.yml to prevent any
further auto-download regardless of future go.mod changes
All tests pass locally with GOTOOLCHAIN=local.

Add Web Interface section covering:
- How to build the server binary (make build-server / make build-all)
- How to run it with the --addr flag
- What the web UI does and all API endpoints (POST /api/traverse,
GET /api/traverse/{id}, SSE stream, GET /api/health)
- Request/response shapes and SSE event format
Also update Makefile with build-server and build-all targets, and
expand Project Structure and Development sections to include the
new cmd/server/ and web/api/ packages.

Three bugs fixed:
1. processReferral was calling ResolveNS with ref.Name (the query domain,
e.g. '800adventures.com.au.') instead of ref.Bailiwick (the NS hostname,
e.g. 'ns-a.hansenits.com.'). This caused the sub-traversal to look up the
wrong name and always fail to find the nameserver's IP address.
2. In ResolveNS (and Referral.Resolve), child referrals whose name matched the
visited set were unconditionally skipped. When the .com TLD returns glue A
records for the target NS alongside its delegation, the child referral has
addresses and should be queried directly rather than skipped.
3. FormatRecord was prepending the DNS header fields and then appending
rr.String() which already includes those same fields, producing doubled
output like 'example.com. 300 IN A example.com. 300 IN A 1.2.3.4'.
Now simply returns rr.String().
Additional improvements:
- Results section deduplicates terminal results: same NS failure or same
(NS, answer) pair is merged with summed probability, avoiding the same
nameserver appearing 15 times with 6.7% each.
- Result lines now include the NS hostname (from Bailiwick) and use the
compact rdata format, e.g. '33% ns-a.hansenits.com answered with 13.54.63.231'.

Add Resolver interface, BasicResolver, and CachingResolver to internal/dns.
CachingResolver wraps any Resolver with an in-memory cache keyed by
(server IP, name, type, class). Cache entries respect DNS TTL from
responses, falling back to a configurable default TTL. Thread-safe
using sync.RWMutex. Includes Len, Clear, and PurgeExpired methods
for cache management.
Closes HAN-379 (Phase 2.2).

Add RootServer struct and DiscoverRoots function that queries the local
resolver for NS records of the root zone, resolves each root name to
A/AAAA addresses, and returns a list of RootServer structs.
Supports:
- Default: discovers a single root server from local resolver
- --root-server override to target a specific root server
- --all-root-servers to discover all 13 root servers
- --root-aaaa flag to include IPv6 addresses
Includes unit tests for all helper functions and integration tests
that skip gracefully when no resolver is available.
