clawbot 3871d6228e Sanitize file names taken from server metadata (closes #9)
check / check (push) Successful in 37s
A file title or album name decrypted from server data could name a path
outside the chosen directory (`../../.ssh/authorized_keys`). One module,
src/filename.ts, now makes such names safe for `quak get`/`get-thumb`
without `--out`, downloadFile/downloadThumbnail without outPath, and the
backup and metadata backup trees. Originals-cache extensions are limited to
letters and digits. A user-supplied path is still used as is. decryptFile
reads a missing or non-string title as "" and rejects metadata that is not
a JSON object.

clawbot ead083c1d6 Carry file size, thumbnail size, and deletion flag through decryptFile (closes #37)
check / check (push) Successful in 25s
decryptFile now sets file.size/thumbnail.size from raw.info (undefined when absent) and carries an optional isDeleted on EnteFile. Plain EnteFile return, no caller changes; listFiles keeps filtering tombstones. Tests cover the three fields and the size-absent case.

sneak 15d2effc2d Green: unseal shared collection keys with the account keypair
decryptCollection now takes the full key material {masterKey,
publicKey, secretKey} and dispatches on keyDecryptionNonce: present
means an owned collection (secretbox under the master key), absent
means a shared collection (sealed box to our public key). Client
already held the keypair for unsealing the auth token, so it just
passes it through.

sneak f3958e911d Add quak backup-metadata: dump all decrypted metadata to plain JSON
New command: quak backup-metadata <dir>

Dumps every piece of decrypted account metadata into a directory tree
of plain JSON files without downloading any file content. Layout:

    <dir>/
        account.json                    { email, userID }
        collections/
            <id>-<name>/
                _collection.json        { id, name, type, pubMagicMetadata?, ... }
                <fileID>.json           { id, metadata, magicMetadata?, pubMagicMetadata? }

Also adds collection-level magic metadata decryption (magicMetadata,
pubMagicMetadata, sharedMagicMetadata) to decryptCollection, which was
previously only done for files. The server sends these for visibility
settings, sort order, cover photo selection, etc.

6 new tests covering: account.json, per-collection dirs with
_collection.json, collection pubMagicMetadata decryption, per-file
JSON with all three metadata layers, graceful handling of files with
no magic metadata, and incremental re-run safety. 116 total.

sneak d4098c711a Decrypt and persist all file metadata layers
Extends RawEnteFile and EnteFile with optional magicMetadata and
pubMagicMetadata fields. Both are secretstream blobs under the file
key, decrypted to arbitrary JSON (Record<string, unknown>).

pubMagicMetadata carries ML-derived data from the Ente clients:
camera make/model, image dimensions, datetime with timezone offset,
and (when present) captions, editedName, face labels, keywords.

magicMetadata carries private mutable fields like visibility.

Backup now writes per-file JSON at originals/<fileID>.json containing
all three metadata layers (basic + magic + pubMagic).

Live-tested: all 11 files in the dev account have pubMagicMetadata
with SONY DSC-RX1RM3 camera info and 3000x2000 dimensions.

sneak 44718a92a9 Fix file metadata decryption: use secretstream blob, not secretbox
File metadata is encrypted as a single-chunk secretstream blob (the
'decryptionHeader' is the secretstream init header, not a secretbox
nonce). Collection keys and names correctly use secretbox.

Adds decryptBlob(ciphertext, header, key) to the crypto module as a
convenience wrapper for single-chunk secretstream decryption (init +
pull + verify TAG_FINAL).

Live-tested: collection names and file metadata (titles, types, dates)
decrypt correctly from the real Ente API.

sneak f81216333e Phase 5 red: collection and file decryption tests
10 tests covering decryptCollection (key + name decryption from raw
server JSON, type mapping, isShared, missing name, wrong key) and
decryptFile (key + metadata decryption, fileType number-to-string
mapping, file/thumbnail header passthrough, wrong key).

Adds src/model/types.ts with both raw (server) and decrypted (library)
type definitions. src/model/decrypt.ts has throwing stubs.
