docs: Support article CDN URL refresh + plugin SHA bumps (minor)

[claude-yolo]

Night shift report

WHY THIS MATTERS: This is routine archive housekeeping with zero user-facing content changes. The 70+ support article changes are entirely CDN image URL token rotations — Intercom's hosted image URLs have expires= and signature= query parameters that refresh periodically, so every image link in every article gets a new URL on each fetch cycle. The marketplace.json updates are SHA pointer bumps for 3rd-party plugins (ClickHouse, CrowdSec, Dash0, DeepEval, HeyGen, JFrog, Mergify, and others) reflecting upstream commits to those plugin repos. The .metadata.json changes are fetch timestamps.

HIGHLIGHTS:

• 70+ support articles: only CDN image URL tokens changed (expires= / signature= params), no text or structure edits
• marketplace.json: 8 third-party plugin SHAs updated (ClickHouse, CrowdSec, Dash0, DeepEval, HeyGen, JFrog, Mergify, claude-remember) — upstream plugin authors pushed commits
• .metadata.json: timestamp refresh from fetcher run
• No Claude Code doc changes, no CHANGELOG entries, no API changes, no version bump (still 2.1.220)
