The README had grown stale relative to the project's current state. This
brings it up to par with comparable open-source credential tools
(Doppler, Infisical) and agent infra READMEs (Ollama, Continue).
Tier 1 (correctness):
- Fix Tests + codecov badge URLs from manojbajaj95 to agentrhq.
- Drop broken link to docs/specs/authsome-v1.md (removed upstream).
- Replace 3 em-dashes with periods per house style.
- Repoint Docs section links to hosted authsome.agentr.dev/docs instead
of local MDX paths (better reading experience on GitHub).
Tier 2 (close gaps every comparable project has):
- Add Install section before Quick Start with pip and uvx commands.
- Add Community section linking Discord and Issues.
- Add Security section pointing at the responsible disclosure policy.
Critical for a credential tool; was previously absent.
- Add Contributing section linking to CONTRIBUTING.md.
Tier 3 (polish and differentiation):
- Add light/dark wordmark logo at top (reuses the SVG mark shipped to
the docs site, sized for README hero).
- Add header link bar (Docs / Website / Discord / Issues).
- Surface "44 bundled providers" callout near the top.
- Add Agent Integrations section listing Claude Code, Codex, Cursor,
OpenCode, LangChain, LlamaIndex, OpenAI Agents SDK, Anthropic SDK.
- Add Discord badge to the badge row.
- Replace the ASCII art block with the logo image. The ASCII was a
placeholder before a real brand mark existed.
