Add Invokely official statistics MCP entry

[estevecastells]

Adds an unverified MCP entry for Invokely's hosted official-statistics service.

• Uses Cline's documented remote HTTP install syntax with the anonymous trial endpoint. Invokely documents no-account access with a limit of 25 calls per day per IP.
• Links the public MIT stdio adapter repository and states that it does not contain the hosted service backend.
• Leaves verified false for the Cline team's review.

Validation: npm run validate (204 entries) and git diff --check passed. I did not test setup in the Cline client.

Disclosure: I am affiliated with Invokely, and AI assistance was used to prepare this contribution.
