Rewrite script/test to the canonical race-enabled pattern (closes #67)

script/test now runs go test -timeout 30s -race -cover ./..., quiet on success and rerunning verbose on failure. -race exposed a data race on the process-global apex/log logger: Init reconfigured it on every CLI run while other goroutines logged through it. internal/log now mutates the global under the write lock and reads it under the read lock; WithError is dropped because its Entry logged outside that lock, and run() reports a failed command's error via log.Errorf instead (still shown under -q). The corruption fuzz test is scaled to 1500 files / 100 iterations to fit the budget under -race; it pins the same claims at reduced breadth. Independent review ran the Docker lint gate uncached.

 # Completed Steps
 
+- 2026-09-21: rewrote `script/test` to the canonical pattern (30s timeout,
+  `-race -cover`, quiet-first with verbose-on-failure rerun) and fixed the
+  process-global logger data race it surfaced (#67)
+- 2026-09-21: added the canonical `.editorconfig`, made `.gitignore` cover
+  secrets, OS, editor, and Go artifacts, and removed the dead Drone CI
+  references from `.gitignore` and `bin/gitrev.sh` (#72)
 - 2026-08-09: added `.prettierrc`/`.prettierignore`, gave `script/fmt` and
   `script/fmt-check` one shared prettier file set via `script/prettier`, dropped
   the `|| true` that hid prettier failures, and added a node-based Dockerfile
