Sarah Wooders d7793a4474 fix(core): stabilize system prompt refresh and expand git-memory coverage (#9438) ...

* fix(core): stabilize system prompt refresh and expand git-memory coverage

Only rebuild system prompts on explicit refresh paths so normal turns preserve prefix-cache stability, including git/custom prompt layouts. Add integration coverage for memory filesystem tree structure and recompile/reset system-message updates via message-id retrieval.

* fix(core): recompile system prompt around compaction and stabilize source tests

Force system prompt refresh before/after compaction in LettaAgentV3 so repaired system+memory state is used and persisted across subsequent turns. Update source-system prompt tests to explicitly recompile before raw preview assertions instead of assuming automatic rebuild timing.
