Tame Dependabot: minor+patch only, one grouped PR per lane - #95
Merged
Conversation
The first run opened seven PRs at once: the npm groups worked, but github-actions had no group (five individual PRs), and the groups happily proposed React 18->19, js-yaml 4->5, TypeScript 5.9->7 and Vite 6->8. Those are migrations with real blast radius (js-yaml majors touch the round-trip contract), not weekly maintenance. Now: majors are ignored entirely across npm (upgraded deliberately, parity sweep included), weekly PRs carry minor+patch grouped per lane, and actions consolidate into a single grouped PR.

About
The first Dependabot run after #83 opened seven PRs at once. The npm grouping worked, but github-actions had no group (five individual PRs), and nothing limited update types, so the groups happily proposed React 18 to 19, js-yaml 4 to 5, TypeScript 5.9 to 7, and Vite 6 to 8. Those are migrations with real blast radius (js-yaml sits under the round-trip contract), not weekly maintenance.
This commit was meant to ride along in #83 but landed on the branch six minutes after the merge, so it needs its own PR.
New posture: majors are ignored across npm entirely and get done deliberately (js-yaml 5 is already tracked in #87), weekly PRs carry minor+patch grouped per lane, and actions consolidate into one grouped PR. Steady state is at most three quiet PRs a week.
The seven open Dependabot PRs (#88-#94) are being closed in favor of this config; the next weekly run regenerates the legitimate minor/patch updates grouped.
