Summary

During the golangci-lint v2 migration we dropped the noctx linter. Without it, new exec.Command usages can be added without a context or timeout, which was previously caught by lint.

Desired outcome

• Re-enable noctx in .golangci.yml.
• Update the codebase to call exec.CommandContext (or provide context-aware wrappers) for all external command executions.
• Ensure the linter passes without suppressing noctx globally.

Notes

• The git helpers in internal/git already centralize most command execution, so adding contexts there should cover the majority of cases.
• For CLI commands, a background context (or user-supplied timeout) is acceptable when no better signal exists.
