🟡 Changes recommended
Several repository Go version pins still reference 1.26, so the Go 1.27 adoption is incomplete and may cause tooling/docs drift.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
Adopts Go 1.27 across the primary build surfaces (module directive, server container build image) and documents the intended versioning policy in AGENTS.md to keep the minimum toolchain and container build line aligned.
Changes:
- Bump root
go.modminimum toolchain togo 1.27.0. - Update server builder image to
golang:1.27-alpine. - Document the “go.mod minimum vs Docker image patch line” policy in
AGENTS.md.

Set Go 1.27.0 as the module minimum while moving server builds to the Go 1.27 image line. Align generated projects, development docs, and lint tooling with the new baseline while avoiding patch-only requirements for consumers. Signed-off-by: timflannagan <timflannagan@gmail.com>

Description
Adopt Go 1.27 while keeping the module directive at the minimum stable release,
1.27.0. Server container builds use the1.27image line so they receivepatch releases without raising the module minimum for consumers.
Document the distinction in
AGENTS.mdso future Go upgrades keep the moduleminimum and server builder aligned by language version.
Align the tools module, lint configuration, development documentation, and
generated MCP Go projects with the same Go 1.27 baseline. The tools module uses
a Go 1.27-capable
x/toolsversion while retaining the existing linter releaseand modernization baseline.
