git pre-push hooks for linting

[Kiran01bm]

What and Why ?

Local dev-tooling enhancement - Adding pre-push hook for linter checks.

Everything runs in containers (no local Go tools needed), allows consistency i.e same linter version for all developers, catches errors before they reach CI/CD, bypass using git push --no-verify (when needed), doc-updates and simple opt-in integration via make lint, make setup-hooks.

Example:

ζ git push --set-upstream origin kiran01bm/tooling/git-hooks-lint-docker
Running golangci-lint in Docker before push...
pkg/statement/parse_create_table.go:1099:4: QF1012: Use fmt.Fprintf(...) instead of WriteString(fmt.Sprintf(...)) (staticcheck)
			sb.WriteString(fmt.Sprintf(" `%s`", constraint.Name))
			^
pkg/statement/parse_create_table.go:1108:4: QF1012: Use fmt.Fprintf(...) instead of WriteString(fmt.Sprintf(...)) (staticcheck)
			sb.WriteString(fmt.Sprintf("`%s`", key.Column.Name.String()))
			^
pkg/statement/parse_create_table.go:1111:5: QF1012: Use fmt.Fprintf(...) instead of WriteString(fmt.Sprintf(...)) (staticcheck)
				sb.WriteString(fmt.Sprintf("(%d)", key.Length))
				^

❌ Linting failed! Please fix the errors before pushing.

To see detailed errors, run:
  docker run --rm -v $(pwd):/app -w /app golangci/golangci-lint:latest golangci-lint run --timeout=5m

To bypass this check (not recommended), use:
  git push --no-verify
