fix(lint): remove forbidden lint scripts, align coverage/test with n-rules canon

[vitaliytv]

Summary

• Removes scripts.lint / scripts.lint-* from root package.json — the bun.mdc policy-deny gate (bun/package_json) forbids these; lint runs only via npx @7n/rules lint, not package.json scripts.
• Fixes scripts.coverage to satisfy the test/package_json gate: now runs npx @7n/rules lint test --no-fix (matches the substring required by the coverage/mutation lint-detector concern shipped in @7n/rules@1.45.0, which supersedes the older @7n/test coverage direct-invocation canon still shown in the stale bundled docs).
• Fixes scripts.test to include --bun (bun run --bun vitest run), so forked vitest pool processes inherit the Bun engine and can resolve Bun-native built-ins like import { SQL } from 'bun'.
• bun.lock updated via bun i (bumps @7n/rules devDependency to ^1.45.0 to match what was actually resolved; reconciles stale @7n/tauri-components root lockfile entries against current package.json).

Why

These were pre-existing npx @7n/rules lint policy-deny violations in the repo root package.json, surfaced once it entered a lint delta scope — not caused by any unrelated recent change.

Note: a separate, already-tracked vue/package_json violation in owner/package.json (missing vite-plugin-vue-layouts-next / vue-macros) is intentionally left untouched — tracked at mt/lint-fix-vue-packages-c8869493/.

Test plan

• npx @7n/rules lint --no-fix bun test → exit 0 (both violations gone)
• npx @7n/rules lint (delta) → only the pre-existing, separately-tracked vue/package_json violation remains
