chore(obsidian): drop unused vault-registration probe (host owns it)

[senamakel]

content::obsidian_registry (Obsidian vault-registration detection + VaultRegistration) has no caller in tinycortex, tinymemory or any other vendor crate. OpenHuman keeps its own copy as host desktop policy (which third-party app the desktop product deep-links into and where it keeps its config), so this is a dead duplicate. Removes the module, its tests and the dirs optional dependency; the obsidian feature (bundled .obsidian/ defaults) is unchanged apart from no longer pulling dirs. fmt, clippy --all-features -D warnings and cargo test --all-features (1484 lib tests + integration) pass.

Summary by CodeRabbit

• Changes
  • Obsidian support continues to stage the bundled .obsidian/ defaults.
  • The app no longer checks Obsidian configuration files to determine whether a content folder is registered as a vault. Vault registration is handled by the desktop host policy instead.
  • Obsidian vault-registration status is no longer available through the app’s public interface.

description

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: Removes the dead `obsidian_registry` module, its types, tests, and the `dirs` dependency, as this functionality is owned by the host. The change is clean and introduces no new issues. _The code index is behind this pull request (indexed at `6958497ed313`), so retrieved context may be out of date._ _Memory was unavailable (model: cortex: v1/recall: timed out after 10s), so this review ran without it._

e2e

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: Removes the unused `obsidian_registry` module and its `dirs` dependency, simplifying the `obsidian` feature to only stage `.obsidian/` defaults. No end-to-end test covered this removed functionality; any consumer relying on it would see a compile-time error, not a silent regression. Safe to merge. _The code index is behind this pull request (indexed at `6958497ed313`), so retrieved context may be out of date._ _Memory was unavailable (model: cortex: v1/recall: timed out after 10s), so this review ran without it._

📝 Walkthrough

Walkthrough

The obsidian feature now covers staging bundled .obsidian/ defaults. The vault registry probe, its public API and types, the feature-gated module declaration, and the related tests were removed. The optional dirs dependency was also removed.

Changes

Obsidian feature scope

Layer / File(s)	Summary
Remove registry probing and narrow feature scope Cargo.toml, src/memory/store/content/mod.rs, src/memory/store/content/obsidian_registry*	The obsidian feature no longer enables dirs or declares the registry module. The registry probe, its public types, and its tests were removed.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: 🔵 Low · up to 0ba41

The change intentionally removes registry probing while retaining bundled defaults staging. It is mergeable with awareness of the public API removal; no supported consumer breakage has been established.

Architecture Summary

Architecture risk: 🔵 Low · up to 0ba41

Before / after behavior

• observed — Modified behavior in Cargo.toml: The obsidian feature description now covers staging bundled defaults only and assigns vault-registration detection to the host; the feature changes from ["dep:dirs"] to an empty dependency list.
• observed — Modified behavior in Cargo.toml: Removed the optional dirs dependency previously used for per-OS Obsidian vault-registry probing.
• observed — Modified behavior in src/memory/store/content/mod.rs: The module-layout documentation now describes obsidian interop as staging bundled defaults; it no longer mentions vault-registration detection.
• observed — Modified behavior in src/memory/store/content/mod.rs: Removed the obsidian_registry module declaration gated by the obsidian feature.

Account for the removed public module.

With the obsidian feature enabled, downstream crates that import obsidian_registry can fail to compile because pub mod obsidian_registry was removed. If this crate has supported downstream consumers, document the breaking change and apply the appropriate version bump. The repository does not define a deprecation requirement, and the crate is currently marked publish = false.
