* ci: add --affected filtering and fix Turbo cache invalidation
- Remove globalDependencies **/.env which invalidated all caches on any .env change
- Move 40+ env vars from globalEnv to build-specific env (lint/format/typecheck don't need DB_URL etc.)
- Add per-task inputs with test file exclusions so test changes don't trigger build/typecheck
- Enable affectedUsingTaskInputs for task-level --affected detection
- Add --affected to all turbo commands in CI (lint, format, typecheck, build)
- Add fetch-depth: 0 for proper git history comparison
- Add Docker Buildx + GHA layer caching for E2E builds
* ci: add Cloudflare remote cache for Turborepo
Configure turborepo-remote-cache-cloudflare as the remote cache backend.
This commit can be reverted independently to disable remote caching.
* fix(ci): set TURBO_SCM_BASE for --affected to work in PRs
Turbo defaults to comparing against `main`, but PRs target `dev`.
Without explicit base/head refs, --affected falls back to running
all tasks. Use the PR base SHA for pull_requests, the before SHA
for pushes, and HEAD~1 as a last resort.
* perf(typecheck): exclude bundled .cjs/.css from tsc
websocket (835K lines) and tasks (755K lines) had bundled output
files being typechecked due to `include: ["."]` in their tsconfig.
Full typecheck drops from ~70s to ~26s.
* perf(turbo): scope topo task inputs to package.json only
The topo virtual task had no explicit inputs, defaulting to all files.
This caused any source change to cascade cache invalidation through
all dependent packages via ^topo. Since topo is only for dependency
ordering, its hash should only change when dependencies change.
* fix(turbo): disable remote cache signature verification
The cache lives on a private CF worker, signature verification
just adds noise without security benefit.
* fix(turbo): remove runtime env vars from build cache key
These env vars (DB_*, AUTH_*, DOCKER_*, etc.) are all runtime
configuration provided by users when running the Docker container.
They don't influence the build output since Next.js standalone mode
reads process.env at runtime and SKIP_ENV_VALIDATION=true skips
validation during build. Listing them in build.env caused unnecessary
cache busting in local dev.
Also restores coverage report comments per review feedback.
* fix(turbo): include test files in typecheck cache inputs
Test files must be typechecked — excluding them from typecheck inputs
caused changed tests to skip type validation.
