Release v0.13.0

Highlights

• Pluggable HttpTransport for curl/wget — embedding hosts can direct all
  sandbox HTTP through their own boundary (egress gateway, proxy, audit layer)
  by injecting a transport via BashBuilder::http_transport. bashkit keeps
  enforcing policy (allowlist, SSRF precheck, hooks, credential injection,
  bot-auth signing, response caps) before every dispatch; the transport
  receives the merged signed headers, timeouts, the SSRF precheck's pinned
  addresses, and the response size cap, and returns typed errors
  (Denied/Timeout/TooLarge/Transport) that map onto curl exit codes
  (7/28/63/1). Mirrors fetchkit's transport injection so one host egress
  implementation can back both libraries. See specs/http-transport.md
  (#2147).
• xargs -P parallel execution — -P/--max-procs runs command batches
  concurrently, with --process-slot-var exposing the slot index to each child
  (#2126).
• ls -d/--directory — list directories themselves instead of their
  contents (#2134).
• bashkit-eval reimplemented on the mira framework — the LLM eval harness
  now runs on mira (#2129).
• Linear-time glob * matching (TM-DOS-031) — replaces the pathological
  backtracking that allowed exponential blowup on adversarial patterns
  (#2142).

Breaking Changes

• HttpHandler removed. BashBuilder::http_handler and
  HttpClient::set_handler are replaced by BashBuilder::http_transport /
  HttpClient::set_transport (no compatibility shim, per repo policy).
  Migration: implement HttpTransport — wrap the old
  (method, url, body, headers) logic in execute(HttpTransportRequest)
  and return HttpTransportError variants instead of String.
  • Before: .http_handler(Box::new(MyHandler))
  • After: .http_transport(Arc::new(MyTransport))
