Org profile README has stale repo links, a member-only Discord URL, and duplicated sections

[rahlk]

What's wrong
The org profile README has accumulated link rot, duplication, and structure that grew section by section.

Broken or stale:

• codeanalyzer-ts and cocoa-py resolve only via GitHub rename redirects (now codeanalyzer-typescript and cocoa-mcp). Nothing 404s today, which is why this went unnoticed — the links break only if a name is ever reclaimed.
• The Discord link is a discord.com/channels/<guild>/<channel> deep-link. It resolves for people already in the server and fails for everyone else, exactly inverting its purpose.
• The Contact table displays rangeet.pan@ibm.com but the mailto: points at gmail.
• The <picture> element's fallback <img> has no src attribute, so it has no working fallback.
• badge.fury.io/py/cldk and opensource.org/licenses/Apache-2.0 both 30x-redirect.

Live but not worth linking:

• npm @codellm-devkit/cldk is 0.0.0-pre-alpha, published April 2025 and never updated.
• codeanalyzer-go (124 KB) and codeanalyzer-rust (93 KB, last pushed Feb 2025) are stubs.

Duplication:

• "Documentation and Examples" repeats bullets already under Getting Started.
• The second code example differs from the first by two words.

Where
profile/README.md in codellm-devkit/.github, rendered at https://github.com/codellm-devkit.

Expected
Every link resolves without relying on a redirect, no section duplicates another, and the page is restructured on the shape of the Model Context Protocol org profile README.

COCOA references come out entirely for now — the org has three COCOA repos (cocoa, cocoa-mcp, cocoa-ts) where the README describes one, and the landing page is the wrong place to settle that.

Additional context
Definition of done

• Every URL returns 200 without a redirect, except discord.gg, whose 301 is Discord's own canonical shortener.
• No link targets a stub repo or a pre-alpha package.
• Every mailto: matches the address displayed beside it.
• No occurrence of "cocoa" in any form.
• The logo renders in both themes and its <img> fallback has a src and a descriptive alt.
