* feat(v2ex): add node, user, member, replies, nodes commands
Add 5 new public API commands to the v2ex adapter:
- node: browse topics by node name
- user: list topics by username
- member: show user profile
- replies: list topic replies
- nodes: list all nodes sorted by topic count
All commands use strategy: public, browser: false.
* test(v2ex): add E2E tests for node, user, member, replies, nodes commands
* docs(v2ex): update adapter docs with new commands
* fix(v2ex): address review findings - rate-limit guards, sort verification, docs
* docs(v2ex): update README command tables and add user example
* test(v2ex): improve test quality - soft guards, value assertions, smoke tests
- Replace isExpectedChineseSiteRestriction with if(code===0) soft guard
(V2EX is globally accessible; YAML fetch doesn't throw FETCH_ERROR)
- Add value assertions: member username===Livid, limit effectiveness
- Add smoke tests for node, member, replies, nodes commands
* fix(v2ex): add url field to node/user commands, add missing user smoke test
- Add url to node.yaml and user.yaml pipeline map steps and columns
(V2EX API provides item.url; improves usability for follow-up lookups)
- Add v2ex user smoke test (other 4 new commands all had smoke tests; user was missing)
- Update E2E assertions to verify url field in node/user results
