Resolves the build half of sow-tools#60 and closes the CLI gap sow-tools#53's
sweep found: PR #71 shipped #53's original surface, not the one #56, #62 and
#65 settled.
- `depot.KeyStore` (`ProbeKey`/`PutReader`/`GetKey`) addresses the zone by
object key instead of by depot sha, reusing the existing IPv4-pinned
transport, retry and tri-state probe. The sha-addressed `Backend` now rides
on it; no new HTTP client.
- `nwsync` gains a sink: the zone by default, a local tree with `--out DIR` as
the conformance path. Blobs upload as they are produced, the index lands
last, and a blob already in the zone is skipped without paying for
compression.
- CLI is now `emit [--as NAME] [--out DIR] <artifact-key> <file>` and
`assemble --group-id N [--tlk-key KEY] [--out DIR] <artifact-key>...`.
Indexes live beside their artifact with the extension replaced, derived in
one place. Flags may follow positionals, which cost a run during sow-tools#59.
- Fail-closed: an artifact key whose digest does not match the file is refused,
and `assemble` refuses an artifact with no index rather than publishing a
manifest missing a hak.
Conformance re-checked through the new CLI against upstream nwn_nwsync_write
2.1.2 on sow_vfxs_01.hak: the manifest is still byte-identical.

Builds sow-tools#53. Format spec followed is the resolution comment of sow-platform#94, checked line by line against niv/neverwinter.nim at HEAD (`nwsync.nim`, `compressedbuf.nim`, `nwsync/private/libupdate.nim`).
## What lands
`crucible nwsync emit <artifact> --out DIR` — explodes one `.hak`/`.erf`, or one loose file such as the TLK, into NWSync blobs plus a NSYM v3 manifest covering only that artifact, with the same `.json` sidecar upstream writes. Blob path `data/sha1/<h0h1>/<h2h3>/<sha1>`, body in NWCompressedBuffer framing (magic `NSYC`, version 3, algorithm 2, uncompressed size, zstd header version 1, dictionary 0, raw zstd frame). The sha1 that names a blob is over the uncompressed bytes.
`crucible nwsync assemble --order NAMES --entries DIR --out DIR [--group-id N]` — merges the per-artifact manifests into one, reading no bulk data at all. Merge rule is resref shadowing, not concatenation: a resref in more than one artifact resolves to the earliest artifact in `--order`, which is how the game resolves it. `--group-id` stays caller-supplied (1 current, 2 testing; 0 is absent, matching upstream omitting a zero integer meta field).
Rules taken from upstream and not re-invented: `nss`/`ndb`/`gic` always skipped; an unresolvable restype is a hard error, not a skip; a resource over 15 MB fails closed; no `latest` file and no `.origin` file, ever. A `.mod` is refused outright — a persistent world publishes no module contents, so the module contributes no bytes.
## Two deliberate departures
- **Emitter version is its own field, not the build revision.** `emitter_version` is a constant bumped only when emitted bytes change. Keying the refuse-to-merge check on `created_with` would invalidate every published index on every unrelated crucible commit and force a re-emit of the whole 15 GB corpus — the opposite of "nothing downstream ever needs the hak again".
- **`SOURCE_DATE_EPOCH` pins the sidecar timestamp.** The manifest itself was already deterministic; the sidecar's `created` was not, against the determinism rule in `docs/consumer-contract.md`.
## Not in this PR, and why
- **Direct upload.** Only the local `--out` sink exists, which is the conformance path. The upload sink and the mid-hak-failure question are sow-tools#60, and the consumer wiring is #65.
- **The conformance run against upstream.** sow-tools#59 owns getting `nwn_nwsync_write` running and capturing reference output. The format here was read from upstream source rather than from its output, so the byte-for-byte manifest comparison and the after-decompression blob comparison still have to happen — that is what #59 is for. The tests in this PR check the layout against the spec, so a shared misreading would pass them.
- **The `artifacts/haks/sha256/<a>/<b>/<sha256>.nsym` location.** emit writes `<out>/<name>.nsym`; where a publisher puts it is the publisher's business (#65).
- **The acceptance gate** — a real client syncing from an assembled manifest — is unchanged and still open.
## Checks
`make check` green (vet, unit tests, shellcheck, yamllint, workflow contract), `make smoke` green with the new builder, `nix build .#crucible` produces `crucible-nwsync`.

Closes#66.
`depot status` and `depot get` chose a depot tree on disk with `--target local`, taking the root from `DEPOT_DIR`. One decision, two flags — and `--target local` with no directory anywhere was valid but meaningless.
Now they take `--out DIR`, matching the crucible nwsync surface. `--target` names remote backends only (`bunny|cdn`). Passing both exits 64.
- `--target local` stays as a deprecated alias for `--out $DEPOT_DIR`, listed in the hidden-alias table in `docs/command-surface.md`. Nothing in `wrappers/` calls depot, but the three repos in `wrappers/consumers.txt` are out of reach from here, so the alias stays.
- `status --source` was already unused; it now warns "ignored; use --out DIR" instead of accepting silently.
- Fixes a real parse bug found on the way: the documented `depot get <sha> <dest> --target cdn` form never parsed its flags, because Go's `flag` package stops at the first positional. Positionals are split off by hand now; both orders are tested.
- Registry usage strings and `docs/command-surface.md` synced — that doc still said depot was unwired.
Not converted: `push --source` and `pull --dest`. Neither is `--target local`; one names a read source, the other a remote pull's destination. Say the word if they should become `--out` too.
`go test ./...` green.
