Pi Mono: Session Safety Under Concurrency

PR 9179 stops tree navigation from corrupting compaction results if a navigation happens…
Second theme: packaging fragility. PR 9170 fixes a fresh install of the coding agent that was broken because a runtime dependency on the Pi Server package was missing — this affected ordinary imports, not just experimental features. PR 9172 follows up to prevent that class of defect from being published again by…
Third, smaller theme: model catalog upkeep. Commit 0dbf2b7 and PR 9093 both remove an experimental Grok build from the built-in xAI catalog. Commit 17de82d adds support for GPT-6 Astra.
