Fix #273: Audit trails for multi-agent task execution

[JiwaniZakir]

Closes #273

Motivation

Issue #273 identified a need for cryptographic audit trails in multi-agent workflows. The community ecosystem section in README.md lacked a listing for asqav, which provides signed records for task transitions, agent handoffs, and outputs in KaibanJS deployments.

Changes

README.md, line ~609 — Adds asqav to the community projects list between kaiban-distributed and the community-maintained disclaimer. The entry links to https://asqav.com and describes its core value: cryptographic signing of each task transition, agent handoff, and output for auditability.

README.md, line ~612 — Updates the disclaimer from singular ("Community-maintained project") to plural ("Community-maintained projects") and from "the project author" to "the respective project authors", accurately reflecting that there are now multiple community-maintained entries in this section.

Testing

Manual verification steps:

1. Render README.md and confirm the asqav bullet appears in the correct position within the "Community Projects" section, after kaiban-distributed.
2. Confirm the link https://asqav.com resolves and the description accurately reflects the project's functionality.
3. Confirm the disclaimer immediately below the list reads "Community-maintained projects" (plural) with "respective project authors" — no leftover singular phrasing.
