From e3ada13adf81e7a6a251aad2b6db573fe48bbd6e Mon Sep 17 00:00:00 2001 From: rabbitblood Date: Fri, 17 Apr 2026 14:47:07 -0700 Subject: [PATCH] fix(slack): use blocks API for mrkdwn rendering + restore Level 3 Slack's chat.postMessage renders the text field as plain text when username override is used. Switching to blocks with type=mrkdwn forces rich formatting (bold, links, code, dividers). Also restores FetchWorkspaceChannelContext that was lost in rebase.
