chore(dsh-plugin-browserskill): prepare the package for npm publishing

- @browser-skill/ui and @remixicon/react move to devDependencies (the client
  bundle inlines both; the host face never imports them — verified).
- Drop private, add license: MIT, ship the repo-root MIT LICENSE in files.
- peerDependencies: add the runtime-required @deepseek-ai/schemastery, and
  the previously dangling meta entries @deepseek-ai/dsh-attachment and
  @deepseek-ai/dsh-llm (optional, matching actual type-level use).
- prepack runs the full build; npm pack now yields exactly 7 files
  (lib/index.mjs, lib/index.d.mts, lib/client.cjs, cordis.patch.yml,
  README.md, LICENSE, package.json).
- publint clean: the client face ships as lib/client.cjs (CJS extension in
  a type:module package); add lint:publint script. Built declarations pass a
  NodeNext consumer typecheck (strict, skipLibCheck false).
