Andy Dixon ec204f0ea2 Add cp, folder mv, get -r, and unlock/lock to remember the key
Filesystem basics: mv now moves folders as well as files, and like mv(1)
a NEW ending in / or naming an existing folder means into it. cp copies a
file, or a folder with -r, by writing new records that share the
original's objects, so it is instant and takes no space; rm already keeps
objects another record still uses. New records go first, so an
interrupted move leaves both names, never neither. get -r extracts a
folder, keeping its structure.

vault unlock [--for 5m] checks the passphrase and starts the binary again
as a hidden __agent process, handing it the suite ID and seed over a pipe.
The agent keeps them in mlocked memory, with core dumps off and (on Linux)
PR_SET_DUMPABLE cleared, serves them on a Unix socket in a 0700 per-user
directory whose owner is checked on every use, and wipes them and exits
at a hard deadline or on vault lock. Commands ask it first unless
VAULT_PASSPHRASE is set, and genkey stops any agent left for that path.

Guide, man pages (new vault-cp, vault-unlock, vault-lock), README and
screenshots updated; the guide's error table is split so it fits.

Andy DixonandClaude Opus 5.5 0d45ecea59 Add rm -r for folders, and make ls list one folder level
rm -r FOLDER deletes a folder and everything under it, records and
objects, so the space is freed. It lists what will go (the first 20
names, then a count) with the total size and asks on the terminal; no
answer or no terminal deletes nothing. -f skips the question and makes a
missing name a no-op, -rf and -fr combine them, and rm -r / is refused.
Objects still in use are worked out once per delete, not once per file.

ls now shows one level, like ls(1): sub-folders once with a trailing
slash, their total size and newest date, then the files, with names
relative to the folder. list keeps the recursive listing of full names
that scripts pipe through cut -c31-, and ls -r is the same.

Docs, man pages, the guide (new rm-r screenshot) and README follow.

Andy DixonandClaude Opus 5.5 eea16c9076 Chunk objects, shard the store, and make filler configurable
File bodies are now cut into 4 MiB objects, the last padded to its
power-of-two bucket, so every object is 64 KiB to 4 MiB whatever the file
size. Object IDs are HMAC'd from a secret per-record seed, so nothing on
disk links a file's pieces, and each object still leads with its own ID,
binding it to its record and position. Chunks are encrypted and synced by
a small worker pool so their fsyncs overlap.

records/ and objects/ are sharded into 256 subdirectories by ID prefix,
all created at init, with every shard's mtime pinned to the epoch.

vault init --filler SIZE writes at least SIZE of filler. Filler entries
are now real entries for a throwaway key, of log-uniform random sizes, so
they carry multi-chunk files like a real collection.

The marker becomes VAULT 2; earlier vaults are not supported.

Andy Dixon be09659f8f Add decoy passphrase
genkey optionally takes a second passphrase that unlocks a separate
decoy identity. Every command run with it sees and changes only decoy
files; records sealed to the other key are skipped silently.

The key file always carries two equal-size slots in random order, with
random bytes in an unused slot, and both slots are always tried. init
seeds each vault with 8-32 entries sealed to a discarded key, so real
files are indistinguishable from filler to a decoy-only holder.

Andy Dixon d95f2d04a4 Initial vault: single-binary post-quantum file vault
Strip Fury back to its vault functionality in one `vault` command:
genkey, init, add (file or directory, optional folder inside the vault),
list, get, mv and rm.

The hybrid FrodoKEM-640 + ML-KEM-768 encryption core is kept under
internal/pqcrypt. Signing, policies, profiles, backups, SSH remotes,
FIDO2, agents, provenance and compression are removed.
