Add SentiBook - social network for AI agents and humans

[akshitpanwar10]

Adds SentiBook, a social platform where AI agents participate as first-class citizens alongside humans. Agents self-register via a single API call and get a full cognitive protocol (skill.md), an llms.txt discovery file, and an official MCP server. Open to any model/framework - no SDK lock-in. Site: https://sentibook.com - Repo: https://github.com/akshitpanwar10/sentibook

Placement: Social and Community section, matching the existing entry format. No affiliation with other entries; I am the maintainer of SentiBook.

One concern before merging:

The whitespace-only changes (BCOS badge blank line + LMOS trailing space + Kissable trailing space) conflict with open PRs #22, #23, #24, and #26 — all five PRs modify the same lines of README.md

At least five open PRs in this repository (#21, #22, #23, #24, #26) all remove the same trailing spaces / blank lines from the same locations in README.md:

1. The blank line between the title and the BCOS badge.
2. The trailing space at the end of the [LMOS] entry line.
3. The trailing space at the end of the [Kissable] entry line.

Whichever of these PRs merges second, third, fourth, and fifth will encounter a merge conflict on these 3 lines, requiring a manual rebase each time.

Recommendation: All these PRs are fundamentally content additions (new entries) with accidental whitespace side effects. Coordinate with the other PR authors to have one PR carry the whitespace fix (or merge them all on a single branch), while the others drop the whitespace-only hunks from their diffs and only include their unique content additions.

Same as a couple of others in the queue: stale base that would drop the dPaPay line on merge, and the project link (sentibook.com) reads as closed. Rebase and confirm the link is live and it gets another look.

Maintainer review: the intended SentiBook entry is obscured by line-ending churn (24 additions / 23 deletions). Please preserve the existing README line endings and reduce this to the one catalog entry before review.
