docs: update codebase concerns and structure maps

[FSM1]

Summary

• Updated CONCERNS.md and STRUCTURE.md in .planning/codebase/ to reflect phases 28-33 completion
• Removed 4 resolved concerns (console.log pervasiveness, web observability gap, monolithic files, sync FilePointer resolution on both platforms)
• Added new concerns: residual console.time in web3auth hooks, mutex unwrap() in FUSE code, fire-and-forget IPNS unenrollment
• Structure updated for Phase 31 decomposition and new modules from Phases 28/30

Test plan

• Review CONCERNS.md for accuracy against current codebase
• Review STRUCTURE.md directory layout matches actual structure

Summary by CodeRabbit

• Documentation
  • Revised codebase architecture, directory and CI/test guidance, and refreshed audit/analysis dates.
  • Clarified unenrollment behavior: web-to-SDK delegated unenrollments and a persisted unenrollment queue to retry on next session; noted silent unenrollment risk if a session closes mid-request.
  • Narrowed web auth/logging concerns and documented remaining typing and observability items.

Walkthrough

Updated planning documentation: CONCERNS.md revises IPNS unenrollment flow, Web3Auth notes, and FUSE/Mutex concerns; STRUCTURE.md updates analysis date, normalizes naming, refines backend/desktop/web layout and test/CI descriptions, and adds a Hook Inventory section.

Changes

Cohort / File(s)	Summary
Concerns Documentation .planning/codebase/CONCERNS.md	Rewrote IPNS unenrollment concern to describe SDK-delegated unenroll via fireAndForgetUnenroll() and persisting unenroll queue in IndexedDB; narrowed web-app concerns to Web3Auth-specific items (unguarded console.time calls and two any casts); removed several obsolete concerns; adjusted FUSE/Mutex panic notes, platform line counts, unit-test gap targets, and audit phrasing.
Structure Documentation .planning/codebase/STRUCTURE.md	Updated analysis date; normalized service/dir naming (e.g., jwt-issuer), added IPFS provider submodules and tests, clarified NestJS/TypeORM migration semantics, revised Tauri/Rust layout and vendor paths, expanded web app lib/components/routes/stores docs (api config, logger, Faro, errors, logout cleanup), standardized styling guidance, clarified test-suite and CI/infra listings, and added "Hook Inventory (Phase 31 Decomposition)".
