Kristoffer Dalby 0f6d312ada all: upgrade to Go 1.26rc2 and modernize codebase
This commit upgrades the codebase from Go 1.25.5 to Go 1.26rc2 and
adopts new language features.

Toolchain updates:
- go.mod: go 1.25.5 → go 1.26rc2
- flake.nix: buildGo125Module → buildGo126Module, go_1_25 → go_1_26
- flake.nix: build golangci-lint from source with Go 1.26
- Dockerfile.integration: golang:1.25-trixie → golang:1.26rc2-trixie
- Dockerfile.tailscale-HEAD: golang:1.25-alpine → golang:1.26rc2-alpine
- Dockerfile.derper: golang:alpine → golang:1.26rc2-alpine
- .goreleaser.yml: go mod tidy -compat=1.25 → -compat=1.26
- cmd/hi/run.go: fallback Go version 1.25 → 1.26rc2
- .pre-commit-config.yaml: simplify golangci-lint hook entry

Code modernization using Go 1.26 features:
- Replace tsaddr.SortPrefixes with slices.SortFunc + netip.Prefix.Compare
- Replace ptr.To(x) with new(x) syntax
- Replace errors.As with errors.AsType[T]

Lint rule updates:
- Add forbidigo rules to prevent regression to old patterns

forbid:
# Forbid time.Sleep everywhere with context-appropriate alternatives
- pattern: 'time\.Sleep'
msg: >-
time.Sleep is forbidden.
In tests: use assert.EventuallyWithT for polling/waiting patterns.
In production code: use a backoff strategy (e.g., cenkalti/backoff) or proper synchronization primitives.
# Forbid inline string literals in zerolog field methods - use zf.* constants
- pattern: '\.(Str|Int|Int8|Int16|Int32|Int64|Uint|Uint8|Uint16|Uint32|Uint64|Float32|Float64|Bool|Dur|Time|TimeDiff|Strs|Ints|Uints|Floats|Bools|Any|Interface)\("[^"]+"'
msg: >-
Use zf.* constants for zerolog field names instead of string literals.
Import "github.com/juanfont/headscale/hscontrol/util/zlog/zf" and use
constants like zf.NodeID, zf.UserName, etc. Add new constants to
hscontrol/util/zlog/zf/fields.go if needed.
# Forbid ptr.To - use Go 1.26 new(expr) instead
- pattern: 'ptr\.To\('
msg: >-
ptr.To is forbidden. Use Go 1.26's new(expr) syntax instead.
Example: ptr.To(value) → new(value)
# Forbid tsaddr.SortPrefixes - use slices.SortFunc with netip.Prefix.Compare
- pattern: 'tsaddr\.SortPrefixes'
msg: >-
tsaddr.SortPrefixes is forbidden. Use Go 1.26's netip.Prefix.Compare instead.
Example: slices.SortFunc(prefixes, netip.Prefix.Compare)
