Replaces Dependabot with Renovate. The new setup:
- One PR per ecosystem (GitHub Actions, Go modules + Makefile go-tool
pins, npm, Python via uv, Nix flake), opened weekly on Mondays with a
5-day release-age cooldown. Vulnerability PRs ship next-day via daily
cron + Renovate's `vulnerabilityAlerts` schedule bypass.
- All `uses:` action refs SHA-pinned with patch-level version comments
(same format as #36971, which this supersedes);
`helpers:pinGitHubActionDigests` keeps future bumps in that format.
- `renovatebot/github-action` runtime image pinned via the
upstream-recommended `RENOVATE_VERSION` env + magic comment +
`customManagers:githubActionsVersions` preset, so Renovate keeps the pin
updated.
- Custom regex manager tracks the `*_PACKAGE ?= <import-path>@<version>`
lines in `Makefile` (golangci-lint, swagger, actionlint, etc.) and
groups them into the same Go PR via `matchDatasources: ["go"]`.
- Post-upgrade tasks regenerate `assets/go-licenses.json` (`make tidy`)
and the SVG sprite (`make svg`), gated by an env-level command
allowlist.
- Replaces the standalone `cron-flake-updater` workflow — Renovate's nix
manager tracks `flake.nix` inputs and produces the same `flake.lock`
bump PRs on the regular weekly schedule.
- npm and gomod-replace pins live in `renovate.json5` only;
`updates@17.16.3` reads them from there too, so the standalone
`updates.config.ts` is gone and one source of truth covers both tools.
