Harden the retry classifier and pin per-attempt deadlines (closes #80 )

A POST or PUT is replayed only when every errno in the cause chain is a connect errno, and postJSON/putJSON no longer follow redirects, so a redirect is an ApiError that is not retried. getRetryOptions() returns a copy. New tests pin every errno the classifier names, the cause-chain depth limit, a two-error cycle, and a fresh deadline per attempt for every retrying entry point. The README endpoint list is now the one place naming the requests the replay rule covers; code comments point to it. Model: opus-5-5

  rule covers.
- 2026-09-22: Dropped the deprecated `@types/libsodium-wrappers-sumo` stub from
-  `devDependencies` (issue 27). It shipped no declarations; the types come from
-  `libsodium-wrappers-sumo` itself. `yarn.lock` regenerated by `yarn remove`.
- 2026-09-22: Hardened the client session lifecycle (issue 10).
-  `Client.fromJSON` checks every snapshot field and each key's decoded length
-  and names the bad field; `toJSON` reads the token through
-  `ApiClient.getAuthToken` and throws when there is none; `logout` zeroes the
-  key buffers, and `collectionsSince` re-checks for logout after its request so
-  it never decrypts with zeroed keys. The CLI reports a corrupt session file
-  separately from a missing one (`src/cli-session.ts`).
- 2026-09-22: Sanitized file names taken from server metadata (issue 9). A new
-  `src/filename.ts` holds the one sanitizer, used by `quak get`/`get-thumb`
-  without `--out`, `downloadFile`/`downloadThumbnail` without `outPath`, and the
-  backup and metadata backup trees; it removes separators, control characters,
-  leading dots and Windows device names, and falls back to a name built from the
-  ID for an empty title. Originals-cache extensions are letters and digits only,
-  else `.bin`. A user-supplied path is used as is. `decryptFile` reads a missing
-  or non-string title as "" and rejects metadata that is not a JSON object.
 - 2026-09-22: Rewrote the README API reference (and the Getting Started / usage
  snippets) to match the shipped cache/API library on `next` (issue 53, issue
  13). Documented `Library.open` and its options, the default-read vs `fresh()`
