* feat: replace cidranger with bart improving performance by 3-20x
Signed-off-by: Jason Cameron <git@jasoncameron.dev>
* perf: replace cidranger with bart for IP range checking
- Replace cidranger.Ranger with bart.Lite in RemoteAddrChecker
- Use netip.ParsePrefix instead of net.ParseCIDR for modern IP handling
- Improve performance: 3-20x faster lookups with zero heap allocations
- Update imports to use github.com/gaissmai/bart and net/netip
- Remove cidranger dependency from go.mod
Benchmark results:
- IPv4 lookups: 4x faster (15.58ns vs 63.25ns, 0 vs 2 allocs)
- IPv6 lookups: 3x faster (26.51ns vs 76.96ns, 0 vs 2 allocs)
- Insertions: 20x faster (976ns vs 19,191ns)
- Large tables: 14x faster (5.2ns vs 74.85ns)
* docs: clarify CHANGELOG to not give false impressions

* perf: optimize string concatenation in RemoteAddrChecker hash generation
Replace fmt.Fprintln with strings.Join for 7x faster performance:
- Before: 935.1 ns/op, 784 B/op, 22 allocs/op
- After: 133.2 ns/op, 192 B/op, 1 alloc/op
The hash is used for JWT cookie validation and error code generation.
Comma separation provides the same deterministic uniqueness as newlines
but with significantly better performance during policy initialization.

* feat(lib): implement request weight
Replaces #608
This is a big one and will be what makes Anubis a generic web
application firewall. This introduces the WEIGH option, allowing
administrators to have facets of request metadata add or remove
"weight", or the level of suspicion. This really makes Anubis weigh
the soul of requests.

* feat(lib/challenge): HTTP meta refresh challenge method
Closes#95
This challenge method enables users that don't (or won't) support
JavaScript to pass Anubis challenges. It works by using HTML meta
refresh directives to ensure that the client is a browser.
This is OFF by default. In order to enable it, an administrator MUST
choose to make the default challenge method `metarefresh`.
TODO(Xe):
- [ ] Documentation on this challenge method
- [ ] Amend wording around Anubis being a proof of work proxy in the docs
- [ ] Add configuration file syntax for the default challenge method and settings
- [ ] Test with early customers
