doc: audit pass — fix env= bug, params, pagination, missing wrappers, broken examples

- env= -> environment= across all docs (Pydantic silently ignores env=)
- Remove __version__ check (doesn't exist in module)
- Fix APIClient(debug=True) missing required client_id/secret
- Fix post.listremoved usage (takes no postId, just lists removed posts)
- Fix JS true/false -> Python True/False in code blocks
- Fix parameter names: branchName->branch_slug, username->user_slug, postId->post_id
- Add missing lastEvaluatedKey param docs for list jobs
- Note post.listpublic as unauthenticated endpoint
- Fix pagination examples (LastEvaluatedKey, not ExclusiveStartKey dict)
- Remove non-existent headers param from make_request example
- Fix branch.listbyname example (takes no name arg)
- Add 4 missing wrapper docs: follow, react, trust, votecast
- Fix broken internal links (case-sensitive filenames)
- Fix <environment>_handle_token template artifact
- Add CODE_BUGS.md documenting 4 code bugs found during audit
