Load/Chaos codegen

[skudasov]

This pull request introduces a new code generation tool for chaos and load test templates, refactors the handling of chaos/load test logic into the wasp package, and updates documentation and dependencies across the project. The main themes are test generation tooling, package restructuring, and dependency maintenance.

Test Generation Tooling

• Added a new CLI command gen load to generate load/chaos test templates for Kubernetes namespaces, including options for workload, naming, output directory, and latency/jitter configuration (framework/cmd/main.go).
• Created documentation for the new test generation tool, describing its usage and best practices (book/src/framework/generate.md).
• Updated the book summary to include the new "Generating Tests" section (book/src/SUMMARY.md).
• Added a changelog entry for the chaos/load test codegen feature (framework/.changeset/v0.11.8.md).

Package Restructuring

• Refactored chaos/load test logic from the havoc package to the new wasp/havoc package, updating imports and dependencies in example projects (framework/examples/myproject/chaos/chaos_k8s_test.go, framework/examples/myproject/go.mod). [1] [2] [3]
• Removed havoc from the linter workflow job list (.github/workflows/linters.yml).

Dependency Maintenance

• Updated multiple dependencies in framework/components/dockercompose/go.mod and framework/components/fake/go.mod to their latest versions, including Kubernetes, OpenTelemetry, and several others for improved compatibility and security. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]

Miscellaneous

• Added .gitignore entries for new test output directories (framework/cmd/.gitignore).
• Updated file permission notation in TOML pretty-printing logic (framework/cmd/main.go).

idea: use whatever go version the system is currently using?

TODOs are way to point the user to where he should look, but maybe a better way would be making sure that these lines do not compile and need to be fixed?

I worry that it won't be obvious that this bool includeWorkload also controls generation of the gunCode

Dynamic Go mod version and TODO enforcer will be addressed in next PRs, good ideas 🚀
