[Bug] A message sent while /compact is running will be ignored

Craft Agents Version

0.13.3

Operating System

macOS (Apple Silicon)

OS Version

macOS 15.6

AI Provider

Anthropic API (custom endpoint)

Model

GLM-5.3 (z.ai via Pi provider)

Description

When the user sends a message while compaction is still running, it will show as a queued message. However, when compaction finishes, this message will be ignored; no reply will ever arrive, so the user has to resend it again.

Steps to Reproduce

• Start a session on a Pi provider connection and give it a long history so compaction runs for a while
• Send /compact
• While compaction is still running, send a normal message
• Wait for compaction to finish

Expected Behavior

After the compaction, the upcoming message should be sent and get a reply like always.

Actual Behavior

The bubble shows the Queued chip while compaction runs. When compaction completes, the chip disappears and the session goes quiet.
