Adds src/lib/agent/memory.ts (remember/forget/listMemories, dedupe by
normalised text, formatMemoriesForPrompt) and wires it in: a
"## What you remember" system-prompt section, the remember/forget/
list_memories tools (src/lib/agent/tools-actions.ts, a per-request
factory since these need the actor unlike the static read-only tool
set), a REST view for the UI (/api/ask/memories), and a Memory drawer
in chat-view.tsx (Mine / Shared with everyone, add, delete).
Adjusted src/lib/agent/read-only.test.ts: its blanket "no mutation
calls under src/lib/agent" contract now allowlists the specific write
seams the plan designates (memory.ts here; tools-actions.ts, gateway.ts
and images.ts to follow) instead of forbidding every file, since
memories/requests are specified to bypass the gateway and write
directly.
Live browser check skipped: ask_log doesn't exist yet in the target
PocketBase (pending the user's --apply of Task 1's schema). Covered by
mocked unit tests instead.
