v0.3.3 — cleanup button fix & the vault is data only 🧹📦

Fix: the 🧹 Vault cleanup button works on every install — and the vault is now pure data, with all code and prompts shipped in the repo.

• 🧹 Cleanup button fixed — in 0.3.2 it pointed at a script inside the vault that many installs didn't have yet (the sync that delivered it only ran one release later), failing with Failed to spawn … (os error 2). It now runs the repo's own copy by absolute path — present on every install the moment the update lands. Also fixed: the result summary silently degraded to a generic "Done" instead of showing files/MB cleaned.
• 📦 The vault is data, the repo is code — the autograph maintenance scripts, the nightly-memory format rules and the dbrain-processor prompts moved out of vault/.claude/ into the repo (scripts/autograph/, scripts/memory/instructions/). They now update with the app instead of rotting inside every vault, and the .claude layout — a leftover of the tooling the memory engine was first built with, never a runtime dependency — is gone from new vaults entirely. The per-vault schema.json moves to the vault root (a one-time automatic migration copies it; the legacy folder in existing vaults is left untouched).
• 🧭 Skills go to agent/skills/ only — Iva's always-on instructions now state where skills live, so "install this skill" can never land files in a .claude folder.

Update as usual — iva update or the Update button in Telegram. No manual steps.
