npmjs.com: add orca (orcareplay)

[xizhuomengcontin]

Adds orca to the npm provider so pkgx orca … resolves.

cmds:
  …
  - orca

args:
  …
  orca: npx --yes --package=orcareplay --

Why the explicit args entry rather than the ... default: the command is orca but the npm package is orcareplay, so the default [npx, --yes, --] would look for a package called orca and find the wrong thing. This is the same case chalk → chalk-cli and get-port → get-port-cli already handle, so I followed their shape.

What it is

OrcaReplay (Apache-2.0, Node 20+) records an AI agent's run at the HTTP boundary to its model provider — from outside the agent process — and replays that recording so the same run happens again with no provider called and no API key:

$ orca record claude -- claude -p "fix the failing test"
$ orca replay last
info replay.done reused=6/6 exact=6 divergences=0 exit=0

Ephemeral pkgx orca … suits it well: it is the kind of tool you reach for when a run has gone wrong rather than something you keep installed.

YAML parses clean (10 cmds). Disclosure: I maintain the package.
