Add script to sync Go version across repo

[doringeman]

Inspired by PR #508, which updates the Go version in a single file.
Once this is merged, I'll use it for that PR.

Adds sync-go-version.sh to keep Go version consistent across:

• go.work, go.mod, cmd/cli/go.mod
• Makefiles (based on GO_VERSION variable)
• Dockerfiles (based on ARG GO_VERSION)

Usage:

• check: verify version consistency
• sync: update all files to match go.mod

Example (2nd commit):

$ ./scripts/sync-go-version.sh check
Go version from go.mod: 1.24.0

Checking Go version consistency...

Mismatch: /Users/dorin/workspace/model-runner/Makefile
  have: GO_VERSION := 1.23.7
  want: GO_VERSION := 1.24.0

Files are out of sync. Run: ./scripts/sync-go-version.sh sync

$ ./scripts/sync-go-version.sh sync
Go version from go.mod: 1.24.0

Syncing Go version to 1.24.0...

Updated: ./Makefile
  GO_VERSION := 1.23.7 -> GO_VERSION := 1.24.0

Done. Review changes with: git diff

Summary of Changes

Hello @doringeman, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a robust shell script designed to centralize and automate the management of the Go programming language version across the repository. By providing check and sync functionalities, the script ensures that the Go version specified in go.mod is consistently applied to other critical configuration files, such as go.work, cmd/cli/go.mod, Makefiles, and Dockerfiles, thereby streamlining updates and preventing version mismatches.

Highlights

• New Go Version Sync Script: Introduced scripts/sync-go-version.sh to automate the process of keeping the Go version consistent across go.work, go.mod, cmd/cli/go.mod, Makefiles, and Dockerfiles.
• Go Version Consistency Checks: The new script includes a check mode to verify if the Go version is consistent across all relevant files, reporting any discrepancies.
• Automated Go Version Updates: The script provides a sync mode that automatically updates the Go version in specified files to match the version defined in go.mod.
• Makefile Go Version Update: The Makefile has been updated to reflect the new Go version 1.24.0.

<issue_to_address>
**issue (bug_risk):** Using `realpath` can break on systems where it is not available (e.g. some macOS setups).

On systems without `realpath` (notably some macOS setups), this will fail and break the script. Consider a more portable approach (e.g. resolving via a short Python `pathlib.Path(...).resolve()` helper, or a `readlink`/`greadlink`-with-fallback), or simply print `$file`, which is already relative to `REPO_ROOT`.

Code Review

This pull request introduces a very useful shell script to synchronize the Go version across different files in the repository, which will certainly help with consistency. The script is well-structured and follows good practices for shell scripting. I have one suggestion to improve its portability across different operating systems.
