* 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.

Gives us many nice things like:
* Windows support for yeet (modulo TecharoHQ/yeet#29)
* Removes the dependency on /bin/sh or /bin/bash thanks to
mvdan.cc/sh/v3
* Checksum-compliant reproducible builds by default

This means that yeet's version will be managed by `go.mod` and
auto-bumped with dependabot. This removes human error from the equation
and ensures that Anubis is always built with the newest version of yeet.
This also makes it trivial to make your own local packages for testing:
```text
go tool yeet
```

* feat(lib/policy): add support for CEL checkers
This adds the ability for administrators to use Common Expression
Language[0] (CEL) for more advanced check logic than Anubis previously
offered.
These can be as simple as:
```yaml
- name: allow-api-routes
action: ALLOW
expression:
and:
- '!(method == "HEAD" || method == "GET")'
- path.startsWith("/api/")
```
or get as complicated as:
```yaml
- name: allow-git-clients
action: ALLOW
expression:
and:
- userAgent.startsWith("git/") || userAgent.contains("libgit") || userAgent.startsWith("go-git") || userAgent.startsWith("JGit/") || userAgent.startsWith("JGit-")
- >
"Git-Protocol" in headers && headers["Git-Protocol"] == "version=2"
```
Internally these are compiled and evaluated with cel-go[1]. This also
leaves room for extensibility should that be desired in the future. This
will intersect with #338 and eventually intersect with TLS fingerprints
as in #337.
