feat: bootstrap Go bindings for trogon-proto

[yordis]

• Gives Go consumers (services, libraries like `trogonerror`, internal tooling) a stable import path for the TrogonStack contract without each one having to install `buf`, run codegen, and stay in sync with the proto repo on every bump.
• Generated code is committed in `gen/` and verified up-to-date in CI, so consumers `go get` and import like any other Go module — no toolchain knowledge required.
• Mirrors `trogonerror`'s release pipeline (release-please, dependabot, semantic PR titles, DCO) so the Go side has the same release cadence and review story as the rest of the stack.

Walkthrough

Adds project scaffolding for trogonproto: Go module and tool versions, Buf codegen config, GitHub CI and release workflows, Dependabot and semantic config, gitattributes for generated protobufs, and README introductory content.

Changes

Go Project & Protobuf Setup

Layer / File(s)	Summary
Module & Dependencies go.mod	Declares module github.com/TrogonStack/trogonproto, go 1.26, and adds protobuf-related requirements.
Code Generation Config buf.gen.yaml	Adds Buf v2 generation config: managed mode, file option overrides for Go package prefixes, Go plugin remote, out: gen, and input module.
Development Tools mise.toml	Specifies tool versions: go = "1.26" and buf = "1.50".
Generated Code Handling .gitattributes	Adds * text=auto eol=lf, marks gen/** and *.pb.go as linguist-generated=true.
Project Documentation README.md	Inserts top-level descriptive content about trogonproto and preserves existing anchor heading.

GitHub CI/CD & Release Infrastructure

Layer / File(s)	Summary
CI Workflow .github/workflows/ci.yml	Adds CI with two jobs: regenerate/verify Buf-generated Go bindings and run Go tests/vet/lint via golangci-lint across Go 1.26.x.
Release Configuration .github/.release-please-config.json	Adds Release Please config for Go (release-type: go, include-v-in-tag true), changelog sections, package mapping to trogonproto, and sentence-case plugin.
Release Manifest .github/.release-please-manifest.json	Adds manifest mapping . to version 0.0.1.
Release Workflow .github/workflows/release-please.yml	Adds workflow to run Release Please action on pushes to main with required permissions and config/manifest paths.
Dependency Management .github/dependabot.yml	Adds Dependabot config for gomod and github-actions, monthly schedule, limit 3 open PRs.
Commit Conventions .github/semantic.yml	Adds semantic config: titleOnly: true and allowRevertCommits: true.

🐰 Small paws tap keys, configs unfurled,
Buf spins the protobuf into Go-world,
CI hums, releases take their leap,
Dependabot watches while I nap, not sleep,
A rabbit smiles—new infra snug as a curl.
