Bumps antd from 0.14.0 to 0.15.0, the release Indelible is waiting on for antd-go's range API. It's a minor bump because byte-range downloads and the --chunk-cache-capacity flag are new.

This PR

• antd/Cargo.toml and antd/Cargo.lock: 0.14.0 → 0.15.0. The lock is hand-edited; CI's --locked check validates it.
• Byte-range support now names its version:
  • openapi.yaml's Range parameter says "Added in antd 0.15.0"; older daemons ignore it and answer 200.
  • antd-go's DataStreamRange docs (REST and gRPC) say "Requires antd >= 0.15.0".
  • The error for a daemon that ignores the range now says "upgrade to antd 0.15.0 or later".
  • antd-go is tagged together with the daemon, which is why its docs change here. antd-rust's matching docs go in the SDK package bump PR, together with its 0.3.0 version.

What 0.15.0 ships (since v0.14.0)

Byte-range downloads (#313, #316):

• REST: Range on GET /v1/data/public/{address}/stream and POST /v1/data/stream.
• gRPC: offset and length on the stream RPCs.
• Only the chunks that overlap the range are fetched. The responses are 206 with Content-Range, or 416 with bytes */size; gRPC OUT_OF_RANGE carries the size in an x-content-range trailer.
• antd-go adds DataStreamRange and DataStreamPublicRange on both clients. antd-rust has the same (feat(antd-rust): byte-range stream methods on the REST and gRPC clients #317), published separately.

Chunk cache cap, a behaviour change (#314):

• The new flag is --chunk-cache-capacity / ANTD_CHUNK_CACHE_CAPACITY. Its default of 64 entries is about 256 MiB; before this, antd used ant-core's default of 1024, about 4 GiB.
• Peak RSS for a 4.5 GiB read fell from 4,654 MiB to 887 MiB.
• Re-reading more than about 256 MiB of distinct chunks now fetches them again; raise the flag to keep more cached.

Other changes:

• ant-core 0.12.0 (ant-cli-v0.3.10) with ant-protocol 4.0.0 (build(antd): repin ant-core 0.12.0 (ant-cli-v0.3.10) #319). antd's own source is unchanged.
• antd-go: Go 1.26 is now the minimum (build(antd-go): fix reachable govulncheck findings; Go 1.26 floor #322). x/net v0.60.0 requires it, and the bump clears govulncheck, along with grpc v1.83.1 and websocket v1.5.3. Modules that import antd-go (Indelible is on 1.25.13) move to go 1.26.0 when they upgrade.
• Release artifacts now include third-party notices (ci(release): ship third-party notices with antd #312).
• Housekeeping:
  • quinn-proto 0.11.19 in the locks for the cargo audit (build(deps): quinn-proto 0.11.19 for RUSTSEC-2026-0338 to -0342 #321); it isn't compiled into antd.
  • proto drift checks for every SDK that commits stubs (ci(proto-drift): drift checks for go/py/dart/ruby/elixir stubs + regenerate stale stubs #315).
  • review follow-ups (Follow-ups from the #315–#317 reviews (drift scripts, range error tests and docs) #318, Dart regen script: Windows paths for native tools; antd-go unsatisfiedSize table test #320).

Testing

• dev2, main at db42419 (this PR only adds the version and doc text on top of it):
  • antd built from main, plus the Go and Rust range checkers rebuilt against main's antd-go (grpc v1.83.1, x/net v0.60.0) and antd-rust.
  • The 4.5 GiB acceptance on a 25-node ant-node 0.22.0 devnet: all pass over REST and gRPC. The 38 ranges fetched the same number of chunks as the pre-merge run, and antd logged 0 errors or warnings.
• Mainnet, read-only, on the build(antd): repin ant-core 0.12.0 (ant-cli-v0.3.10) #319 build (the same compiled antd): 24/24.
  • Canary files downloaded byte-identically on 0.14.0 and the new build.
  • Ranges on a 485 MB file matched archive.org.
• Locally: cargo check --locked passes; for antd-go, go vet, go test and gofmt pass.

After merge

1. Push an annotated tag v0.15.0 at the merge commit. release.yml builds and signs; the stable tag requires signing, and the DigiCert certificate expires 2026-10-17.
2. The auto-tag workflow cuts antd-go/v0.15.0.
3. Add the cache-default and Go 1.26 notes above to the generated release notes.
4. Then do the SDK package bump PR (antd-rust 0.3.0 and the others).
