chore: bump tooling/deps and refactor scheduler counter to atomic.Uint64

[hyp3rd]

• Update golangci-lint from v2.11.3 → v2.11.4 across pre-commit hook, project settings, and Makefile
• Update buf from v1.66.1 → v1.67.0
• Bump github.com/hyp3rd/ewrap v1.3.7 → v1.3.9
• Bump modernc.org/sqlite v1.46.1 → v1.48.1
• Replace plain uint64 counter field in Scheduler with atomic.Uint64, eliminating the need for the atomic.AddUint64 package-level call in favour of the safer, self-contained s.counter.Add(1) method

Pull request overview

This PR updates core tooling/dependency versions and refactors the scheduler’s internal job ID counter to use sync/atomic.Uint64 for safer, self-contained atomic increments.

Changes:

• Bumped golangci-lint and buf versions across project settings, Makefile, and pre-commit hook.
• Updated Go module dependencies (github.com/hyp3rd/ewrap, modernc.org/sqlite) and corresponding go.sum entries.
• Refactored Scheduler.counter from uint64 + atomic.AddUint64 to atomic.Uint64 + s.counter.Add(1).
