chore: modernize CI and update Go toolchain

- Bump Go from 1.19 to 1.26 and update all dependencies - Rewrite CI workflow with matrix strategy (Linux, macOS, Windows) - Update GitHub Actions to current versions (checkout@v4, setup-go@v5) - Update CodeQL actions from v1 to v3 - Fix cross-platform bug in mock/path.go (path.Join -> filepath.Join) - Clean up dependabot config (weekly schedule, remove stale ignore) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

+In [1.0.0](//github.com/imdario/mergo/releases/tag/1.0.0) Mergo moves to a vanity URL `dario.cat/mergo`. No more v1 versions will be released.
+
+If the vanity URL is causing issues in your project due to a dependency pulling Mergo - it isn't a direct dependency in your project - it is recommended to use [replace](https://github.com/golang/go/wiki/Modules#when-should-i-use-the-replace-directive) to pin the version to the last one with the old import URL:
+
+```
+replace github.com/imdario/mergo => github.com/imdario/mergo v0.3.16
+```

 ### Transformers

 Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, `time.Time` is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero `time.Time`?

+Chroma is a syntax highlighting library, tool and web playground for Go. It is based on Pygments and includes importers for it, so most of the same concepts from Pygments apply to Chroma.
+
+This project is written in Go, uses Hermit to manage tooling, and Just for helper commands. Helper scripts are in ./scripts.
+
+Language definitions are XML files defined in ./lexers/embedded/*.xml.
+
+Styles/themes are defined in ./styles/*.xml.
+
+The CLI can be run with `chroma`.
+
+The web playground can be run with `chromad --csrf-key=moo`. It blocks, so should generally be run in the background. It also does not hot reload, so has to be manually restarted. The playground has two modes - for local development it uses the server itself to render, while for production running `just chromad` will compile ./cmd/libchromawasm into a WASM module that is bundled into `chromad`.
