build: update golangci-lint to v2.12.2 with canonical config
Replace the commit-pinned golangci-lint install refs in Dockerfile and
script/bootstrap with the v2.12.2 version pin, and replace .golangci.yml
with the canonical v2-schema config (lint settings now live under
linters.settings, so the lll/funlen/cyclop/dupl thresholds are actually
applied).

Fix all findings surfaced by the newly-applied config:

- goconst: introduce shared constants for repeated status, priority,
  and DNS fixture strings in watcher.go and the notify, state, and
  watcher tests
- dupl: consolidate duplicated ntfy/slack HTTP-error tests and
  SendNotification endpoint-error tests behind shared helpers
- lll: wrap long test table entries and comments; shorten one inline
  nolint justification

# script/bootstrap: install all dependencies needed to build and develop
# this repo. Idempotent: every install is guarded by a check so already
# installed tools are skipped. Base tooling comes from nix, apt, brew,
# or apk (detected in that order); assumes nothing is present.
# golangci-lint and goimports are installed via `go install` at the same
# pinned refs the Dockerfile uses (never "latest").
