Remove temporary Renovate holds on pnpm, TypeScript, and golangci-lint

[kushuh]

Three temporary allowedVersions holds are present in the fleet-wide RENOVATE_PACKAGE_RULES in a-novel-kit/workflows (generic-actions/renovate/action.yaml) to stop Renovate opening PRs that cannot pass CI. Each must be removed once its condition clears; this task tracks that so the holds do not calcify.

1. pnpm — held off 11.12.0

• Why: pnpm 11.12.0 regressed its own global self-installer (createFullPkgId throws Cannot use 'in' operator … 'integrity'), so pnpm/action-setup crashes during CI setup.
• Rule: allowedVersions: "<11.12.0 || >11.12.0" (excludes only 11.12.0).
• Removal: self-clears. Renovate resumes bumping as soon as a fixed patch (11.12.1+) ships. Delete the rule then.

2. typescript — held below v7

• Why: TS7 drops JavaScript API surface needed by the Prettier TypeScript-config loader, and typescript-eslint still caps its peer range below v7.
• Rule: allowedVersions: "<7".
• Removal: manual. Delete the rule once the formatter and typescript-eslint support v7; verify their published peer ranges first.

3. golangci-lint — held off v2.13.0

• Why: its bundled nilness analyzer panics on valid service code with internal error: unhandled builtin recover, breaking both Renovate artifact generation and lint-go.
• Rule: allowedVersions: "<2.13.0 || >2.13.0" (excludes only v2.13.0).
• Removal: self-clears. Validate the first fixed release on the affected service, then delete the rule.
• Evidence: chore(deps): update module github.com/golangci/golangci-lint/v2 to v2.13.1 a-novel/service-narrative-engine#583.
• Implementation: fix(deps): stabilize Renovate Go updates #407.

The TODO above the rules block points back to this issue.

Target date is a review reminder, not a deadline; move it if the upstream fixes have not landed.
