Replace the 'Platform primitives / RossoCortex data plane' narrative with a
project-focused landing page: an org-level intro plus three groups of project
cards (core projects, research collaborations, automation & repo maintenance).
Each card carries only the essence of the project and links to its repository,
where the details, instructions, and examples live.

The earlier platform direction stays on the page as a 'Past activities'
section: the data-plane functions and services cards return as a historical
record (shipped through v0.8), each pointing at the repository where that work
lives today (RossoCortex is renamed to cortex throughout).

The old landing page is additionally archived as a draft backup
(welcome-platform-story.mdx), and the site tagline is updated to match the new
focus.

The GitHub button next to Get started rendered taller than its neighbour:
MDX parsed the multi-line JSX children as a markdown paragraph inside the
link, adding paragraph spacing inside the button. Write the Link on a
single line so both CTAs render identically.

The ecosystem plugin's editUrl now points at this repo instead of the
archived rossoctl/ecosystem-guide, so the landing page's "Edit this page"
link resolves (it previously 404'd on a doubled path).

The historical data-plane/services cards and the archived-repositories
table are gone from the page. The pre-pivot narrative remains available
in the repo as the draft backup (welcome-platform-story.mdx).

Reverts the Accordion now/discontinued extensions, which existed only to
render those cards; the component is back to its pre-PR shape.

The hero's Get started button now anchors to the Core projects section
on the landing page instead of /docs/, which still presents the earlier
platform work. Each project card always shows an explicit Get started
link to its own repository in the footer, so the per-project entry
point is unmistakable even before reading the card.

Match the sibling GitHubStars component and render the card anchors
through @docusaurus/Link instead of raw <a>, and build the repository
URL once per card instead of twice (title and footer Get started
anchor), per review feedback.

Docs: align the org profile repository list with the current focus

Feat: pivot the landing page to the project directory

Callers use secrets: inherit, which passes every secret of the calling
repo to this workflow. A caller that passes ADD_TO_PROJECT_PAT by name
fails today, because the secret is not declared here.

The declaration is required: false, so callers that use secrets: inherit
work as before.

fix: Declare ADD_TO_PROJECT_PAT so callers can pass only that secret

Three pages of the 0.7 and 0.8 docs give the old installer URL,
https://raw.githubusercontent.com/rossoctl/cortex/main/authbridge/install.sh.
That path is a stub in rossoctl/cortex. The stub runs scripts/install.sh
from main. Cortex can delete the stub only when no live page gives its URL.

The new URL, https://www.rossoctl.dev/cortex/install.sh, serves a copy of
the same scripts/install.sh from main. The command does not change, and
--claude-code is still a valid option.
