From b606c773b4ce37d37aa013aa6b599a6e03644f5f Mon Sep 17 00:00:00 2001

Subject: [PATCH] refactor: exclude unused crates from workspace, fix flaky
 tests

Workspace cleanup:
- Exclude from workspace builds (keep directories for future use):
  terraphim_build_args, terraphim-markdown-parser (planned future),
  haystack_atlassian, haystack_discourse, haystack_jmap, haystack_grepapp
  (unused providers), terraphim_repl (superseded by terraphim_agent)
- Comment out grepapp_haystack path dep in terraphim_middleware
- Remove 10 nested crates/*/crates/terraphim_settings/ duplicate dirs
- Update .release-plz.toml for excluded crates
- Remove terraphim-repl references from release-minimal.yml

Test fixes:
- Fix test_save_one_memory in terraphim_config: handle global storage
  singleton already initialized by other tests with different profiles
- Fix test_circuit_breaker_half_open_after_cooldown in terraphim_spawner:
  increase sleep margin from 5ms to 50ms to prevent flaking under load

Refs: #622, #623, #624
