Adds the canonical .golangci.yml (v2 schema, default: all with a small documented disable list) and pins the Dockerfile lint stage to golangci/golangci-lint:v2.12.2 by tag and digest, replacing the previous v1.64.8 digest-only pin. The Makefile invokes golangci-lint unversioned and CI builds via Docker, so no other pins existed.

The v1 to v2 jump surfaced 74 findings; all are fixed with no changes to exported signatures or runtime behavior:

doc comments for the package and all exported symbols; unused handler parameters renamed to _ (revive, 38)
blank-line and whitespace conventions (nlreturn 8, wsl_v5 4, whitespace 1, embeddedstructfieldcheck 1)
errors wrapped with %w instead of %v (err113, 2)
error returns checked or explicitly discarded (errcheck 2, errchkjson 1)
http.NewRequestWithContext + http.DefaultClient.Do instead of http.Post, propagating the handler context (noctx)
fmt.Fprintln(os.Stdout, ...) instead of fmt.Println (forbidigo)
magic numbers named as constants (mnd, 2)
explicit slog.LevelDebug case, same white color as before (exhaustive)
interface{} to any (modernize)
tests moved to package simplelog_test with t.Parallel() (testpackage 2, paralleltest 1)
constructor ordering and long-line wrapping (funcorder, lll)

Three //nolint directives with justifications cover the package's intentional design: gochecknoinits/gochecknoglobals for the install-on-import default logger, and ireturn for NewExtendedEvent returning the exported ExtendedEvent interface.

make check (fmt-check, lint, test) is green. TODO.md Completed Steps updated in the same commit.

Noted while in here, not touched: golangci-lint warns that gomodguard is deprecated since v2.12.0 in favor of gomodguard_v2 (config is canonical and shared, so left as is), and the Dockerfile test stage still pins golang 1.22.12 from 2025-02.

Adds the canonical `.golangci.yml` (v2 schema, `default: all` with a small documented disable list) and pins the `Dockerfile` lint stage to `golangci/golangci-lint:v2.12.2` by tag and digest, replacing the previous v1.64.8 digest-only pin.

Add the canonical .golangci.yml (v2 schema, all linters enabled with a
small documented disable list) and pin the Dockerfile lint stage to
golangci/golangci-lint:v2.12.2 by tag and digest, replacing the old
v1.64.8 digest-only pin.

Fix all findings surfaced by the v1 to v2 jump without changing any
exported signatures or behavior:

- add package and exported-symbol doc comments (revive)
- rename unused handler parameters to underscore (revive)
- check or explicitly discard error returns (errcheck, errchkjson)
- wrap errors with %w instead of %v (err113)
- use http.NewRequestWithContext instead of http.Post (noctx)
- replace fmt.Println with fmt.Fprintln(os.Stdout, ...) (forbidigo)
- name magic numbers as constants (mnd)
- add explicit slog.LevelDebug case (exhaustive)
- interface{} to any (modernize)
- move tests to the simplelog_test package (testpackage) and add
  t.Parallel() (paralleltest)
- move NewWebhookHandler above its methods (funcorder)
- whitespace, line-length, and blank-line fixes (wsl_v5, whitespace,
  nlreturn, lll, embeddedstructfieldcheck)
- nolint with justification for the intentional init/global design
  (gochecknoinits, gochecknoglobals) and interface-returning
  constructor (ireturn)
