docs: point Paperclip docs links at docs.paperclip.ing (#9300)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The public README files are owned discovery surfaces for users who
arrive from GitHub or npm.
> - Some documentation links still used the old
`https://paperclip.ing/docs` redirect path.
> - Redirect hops are worse for users and for SEO because crawlers and
readers do not land on the canonical docs host immediately.
> - Package metadata should still point at the GitHub repository,
because npm package homepages are expected to identify the
source/project page.
> - This pull request updates only explicit documentation links to the
canonical docs subdomain.
> - The benefit is a smaller, clearer link sweep with no package
homepage metadata change.

## Linked Issues or Issue Description

- No public GitHub issue exists for this small documentation maintenance
change.
- Problem: public README documentation links used a redirecting docs URL
instead of the canonical docs host.
- Expected behavior: README documentation links should point directly at
`https://docs.paperclip.ing`.
- Scope: root README, CLI README, and the Hermes adapter README docs
reference.
- Related search results reviewed: #793, #592, #675, and this PR. No
open duplicate PR was found for this README-only canonical docs URL
sweep.

## What Changed

- Updated the root README Docs navigation link from
`https://paperclip.ing/docs` to `https://docs.paperclip.ing`.
- Updated the CLI README Docs navigation link from
`https://paperclip.ing/docs` to `https://docs.paperclip.ing`.
- Updated the Hermes adapter README Paperclip Docs link from
`https://paperclip.ing/docs` to `https://docs.paperclip.ing`.
- Kept all `package.json` homepage fields pointing at the Paperclip
GitHub repository or package-specific GitHub README pages.

## Verification

- `git diff --check origin/master...HEAD`
- `rg 'https://paperclip\.ing/docs|https://docs\.paperclip\.ing'
README.md cli/README.md packages/adapters/hermes/README.md`
- `rg '"homepage": "https://docs\.paperclip\.ing"' -g 'package.json'`
returned no matches.
- Reviewed the final diff against `origin/master`; only the three README
files changed.

## Risks

- Low risk: this is a documentation-only URL update.
- The main review risk is scope creep into npm metadata; that was
explicitly avoided by keeping package homepages on GitHub.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI GPT-5-based Codex coding agent with local shell, git, GitHub
CLI, and Paperclip API tool use.
