S3Storer.Get and Stat returned the raw AWS SDK error for a missing
object, so errors.Is(err, storage.ErrNotFound) was false on the s3
backend while the file and rclone backends honored the Storer contract.
Callers that branch on ErrNotFound behaved differently per backend.
Both now wrap ErrNotFound when the SDK reports a missing object,
leaving every other error intact. The not-found detection is a small
exported s3.IsNotFound helper, also used by HeadObject so the two share
one definition. A test asserts a missing key maps to ErrNotFound on the
s3 backend; it fails without the mapping.

Updates golangci-lint to v2.12.2 everywhere it is pinned and installs the canonical `.golangci.yml`, then remediates every finding the new linter/config surfaces so `make check` is green.
## Version bump
- `Dockerfile` lint stage: `golangci/golangci-lint:v2.11.3-alpine` -> `v2.12.2-alpine` (digest-pinned, date comment updated)
- `Makefile` `deps` target: `go install` moved from the old v1 module path at `@latest` to the pinned `github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.12.2`
- `.golangci.yml` replaced with the canonical config (v2 schema; settings under `linters.settings` so the thresholds actually apply; `default: all` with the standard six disables)
- `script/bootstrap` installs golangci-lint via the system package manager and carries no version pin, so it is unchanged
- CI (`.gitea/workflows/check.yml`) only runs `script/cibuild`, so it needed no change
## Lint remediation
The canonical config surfaced ~3,300 findings across 56k lines. All are fixed, behavior-preserving; incorporates and supersedes the per-package mechanical passes already merged to `main` (refs #61). Highlights:
- `err113`: dynamic errors replaced with package sentinels + `%w` wrapping; comparisons via `errors.Is`
- `goprintffuncname`: printf-style helpers renamed with an `f` suffix (`ui.Writer` message methods, `cli.ReportErrorf`, `database.Fatalf`) and all call sites updated
- `revive` stutter renames: `blob.Handler`, `blob.WithReader`, `blob.ChunkPosition`, `storage.URL`, `storage.Info`; missing doc comments added
- `contextcheck`/`noctx`: `context.Context` threaded through `blob.Packer` and the scanner call sites; context-aware `exec`/`sql` variants
- `funlen`/`cyclop`/`gocognit`/`dupl`: oversized and duplicated functions split into focused helpers (production and test code)
- tests: `t.Parallel()` added where safe (global logger init kept in the serial phase for `-race`), `t.TempDir()`/`t.Helper()` adopted, several suites converted to external test packages
- `gosec`: bounded integer conversions, `ReadHeaderTimeout` on the test HTTP server; remaining warnings suppressed per-site with justifications
- remaining `nolint` directives are rare, targeted, and each carries a reason (e.g. `nilnil` not-found contract in the repository layer, fx module globals, on-disk snake_case struct tags)
- removed the deprecated `log.LogOptions` alias (callers migrated to `log.Options`)
`make check` (tests with `-race`, lint, fmt-check) passes.

Scanner now writes all user-facing output to an io.Writer (os.Stdout
when progress is enabled, io.Discard in --cron mode). This fixes the
long-standing issue where --cron still printed progress lines.
S3 HeadObject now properly distinguishes not-found from other errors
instead of swallowing all errors as not-found.
Config/CLI error messages include actionable hints (where to find the
config, how to generate keys, what storage options exist).
- Implement deterministic blob hashing using double SHA256 of uncompressed
plaintext data, enabling deduplication even after local DB is cleared
- Add Stat() check before blob upload to skip existing blobs in storage
- Add rclone storage backend for additional remote storage options
- Add 'vaultik database purge' command to erase local state DB
- Add 'vaultik remote check' command to verify remote connectivity
- Show configured snapshots in 'vaultik snapshot list' output
- Skip macOS resource fork files (._*) when listing remote snapshots
- Use multi-threaded zstd compression (CPUs - 2 threads)
- Add writer tests for double hashing behavior
- Add gofakes3 for in-process S3-compatible test server
- Create test server that runs on localhost:9999 with temp directory
- Implement basic S3 client wrapper with standard operations
- Add comprehensive tests for blob and metadata storage patterns
- Test cleanup properly removes temporary directories
- Use AWS SDK v2 for S3 operations with proper error handling
