Closes#564
This one is really dumb. Take a seat and listen to my tale of woe.
While @victorvalenca was working on #693 we ran into a strange issue.
The tests would consistently pass on Firefox but instantly failed on
Chrome. After adding increasingly desperate debugging logs to the mix,
we found out that somehow Chrome was randomizing the contents of its
Accept-Language header. This was making the challenge string get
calculated differently, thus making things spuriously fail. I cannot
figure out what causes Chrome to do this other than you being in an
environment where you have more than one "system language" set.
Either way, this should finally fix this issue and bring peace to the
land forever*.

* 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.

Prev it would say that we had allocated 18pb

mem_test.go:135: Memory allocated for 1k extractOGTags calls: 18014398509481978.00
Now it's fixed with

* 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.
