Cas/clean tauri api layer

[Cas Linden (CasLinden)]

Summary

In tauri-api.ts:

• cleaned unused invocation handlers (and their rust counterparts in commands)
• cleaned up types and constants
• now reflects the main.rs (which reads only from commands)

In components:

• replaced direct invoke calls with (exisitng and new) handlers in tauri-api.ts
• now read all types from shared.ts

Docs

• src-tauri/src/README.md — updated commands/ entry to reflect current handler list and tauri-api.ts as the call site
• src/README.md — new frontend architecture overview

Test Plan

Feedback type refactor

I managed to spin up the hono-api receiving these locally, and though drizzle kit was able to confirm that the type refactor does not block or meaningfully impact the ability to receive error data

One test fails for directory picker. Test case received conflicted updates both of which were kept in a merge conflict resolution by copilot-swe-agent.

File	Result	Notes
src/stores/widget-store.test.ts	PASS	25 tests
src/hooks/use-permissions.test.ts	PASS	6 tests (logged plugin-fallback warnings are expected)
src/components/widget/widget.test.tsx	PASS	4 tests
src/components/widget/controls/directory-picker.test.tsx	FAIL (1 failing)	ignores setHostAttr failures without breaking the happy path — expected ["mbp"], got [] (line 223). 9 of 10 tests pass. Pre-existing failure: identical test code/mocks exist on origin/develop and reproduce the same failure (verified by checking out develop's version of the file and running). The fix commit 55dd4a91 is already an ancestor of HEAD; merging develop would not resolve it. Root cause: mocked setDir wrapper calls mockListHosts() (default []) instead of using the hosts field from mockSetDir.mockResolvedValue({hosts: ["mbp"]}).

Think the build error intorudeced elsewhere in e2e changes is addressed by scott elsewhere

[Cas Linden (CasLinden)]

Converting this to draft because it requires serious attention to consolidate with what was merged after

[Juanpe Bolívar (arximboldi)]

Massive diff. To address conflicts, I wonder if it would make sense to recreate it from original prompts. Probably best to tackle after the open PR inflation situation has been taken under control :)

[Cas Linden (CasLinden)]

I wonder if it would make sense to recreate it from original prompts

I wondered that too when I put this on draft, but I think I can salvage it, maybe.

And roger about tackling this later.
