README: product name spelled "WebCMD" in two places, "Webcmd" everywhere else

[rajarshidattapy]

Description

README.md:29 and README.md:31 use WebCMD:

WebCMD learns the navigational context of websites as agents use them…
On top of live browser control, WebCMD adds 3 layers of learnings.

Every other occurrence in the repo uses Webcmd, including:

• the README H1 itself (README.md:25 — # Webcmd)
• docs/docs.json ("name": "Webcmd")
• all 13 docs/*.mdx pages
• skills/webcmd-usage/SKILL.md
• CONTRIBUTING.md, PRIVACY.md

These are the first two body paragraphs of the README, so the inconsistency is above the fold on npm and GitHub.

Suggested fix

Change both to Webcmd.
