Add Knocket live chat service (alongside Chatra/Tidio)

[rrivory]

Adds Knocket as a third chat service, next to the existing Chatra and Tidio integrations.

Knocket is a 100% free live chat widget (one <script> tag) aimed at indie developers and bloggers — free forever, no ads, no seat limits. Powered by Tencent RTC.

Changes

• New partial layout/_third-party/chat/knocket.njk
• Add an elif theme.knocket.enable branch in layout/_third-party/index.njk
• Add a knocket: block to the Chat Services section of _config.yml

Behaviour

• Disabled by default (enable: false); the widget only renders when enabled and identifier is set — no impact on existing sites.
• Mirrors the existing Chatra/Tidio pattern (single async script).

Config example

knocket:
  enable: true
  async: true
  identifier: YOUR_ID   # from https://trtc.io/solutions/knocket

Happy to add a corresponding docs page (third-party-services/chat-services) if you would like.
