Walkthrough

Repository-wide Go version upgrade from 1.26 to 1.26.1 across workflows, go.mod files, Dockerfiles, and documentation. Docker base images updated concurrently (Alpine 3.22 to 3.23). SGR parameter rewriting logic moved between runtime modules.

Changes

Cohort / File(s)	Summary
GitHub Workflows .github/workflows/e2e-tests.yml, pr-tests.yml, release-cli.yml, release-pipeline.yml, snyk.yml	Updated Go version from 1.26 to 1.26.1 in setup-go steps across all CI workflows for consistent build environment.
Go Module Files cli/go.mod, core/go.mod, framework/go.mod, transports/go.mod, examples/mcps/*/go.mod, examples/plugins/*/go.mod, plugins/*/go.mod, tests/*/go.mod	Bumped Go language version directive from 1.26 to 1.26.1 across all module files (40\+ files).
Container Images Makefile, transports/Dockerfile, transports/Dockerfile.local, docs/plugins/building-dynamic-binary.mdx	Updated Docker base images from golang:1.26-alpine3.22 to golang:1.26.1-alpine3.23 and node:24-alpine3.22 to node:24-alpine3.23.
Documentation AGENTS.md, docs/benchmarking/run-your-own-benchmarks.mdx, docs/plugins/writing-go-plugin.mdx, examples/mcps/http-no-ping-server/README.md	Updated Go version prerequisites and references from 1.26 to 1.26.1 in documentation and README files.
SGR Logic Reorganization cli/internal/runtime/sgr.go, cli/internal/runtime/tabmgr.go	Moved rewriteSGRParams function from tabmgr.go to sgr.go; handles colon-separated SGR sub-parameter conversion for color codes (38/48), underline styles (4), and drops unsupported underline color (58).

Poem

🐰 A version bump hops through the code,
From 1.26 to 1.26.1's road,
Dockerfiles dance with Alpine's grace,
SGR colors find their new place,
All workflows run with fresher pace! ✨
