* feat(linkedin): add connections command to list first-degree connections Adds `opencli linkedin connections` — lists your first-degree LinkedIn connections (name, headline/occupation, public id, connected-at, profile URL) via the voyager `/voyager/api/relationships/connections` REST endpoint. - Reuses the shared JSESSIONID csrf-token + x-restli-protocol-version voyager fetch pattern; paginates start/count up to --limit (max 500). - Typed errors: AuthRequiredError (missing session / 401 / 403), CommandExecutionError (malformed payload / missing miniProfile), EmptyResultError (no connections). Live-verified end-to-end against a logged-in account (real connections with occupation + profile URLs). 7 new tests; full suite 5959 passed; audits new=0. * fix(linkedin): harden connections identity handling
