docs(changelog): publish v0.2.18 release notes (#1745)

* docs(changelog): publish v0.2.18 release notes

Today's release covers 13 PRs since v0.2.17. Spotlight is the full Issue
Labels feature (backend + CLI + Web UI), plus the Labs settings tab,
sidebar invitation indicator, and the sharded Redis realtime relay.
Improvements and fixes round out comment rendering, project-icon usage
across the app, self-host env-var pass-through, and several
Windows-specific agent issues.

* docs(changelog): simplify v0.2.18 entries

Trim each line to a short, user-facing sentence; drop implementation
detail (sharded relay, build-id symlinks, --description-stdin, etc.) per
review feedback that the previous draft was too detailed.
