docs(cli): update README & output reference to v0.10.3

Bump CLI docs to v0.10.3 and refresh quick start. README quick-start was simplified (adds login/setup and condenses the flow to intent → discovery → negotiation → review). The CLI output reference was extensively revamped: version bump to v0.10.3, redesigned help layout, updated endpoints/URLs to https, new sections (Negotiations, Contacts, Scrape & Sync), short IDs/keys in lists, improved network/contact displays, updated commands/examples and options. package.json was also updated to reflect the new CLI version.
