flatten: move poc-memory contents to workspace root

Browse source 
No more subcrate nesting — src/, agents/, schema/, defaults/, build.rs
all live at the workspace root. poc-daemon remains as the only workspace
member. Crate name (poc-memory) and all imports unchanged.

// api/anthropic.rs — Anthropic Messages API backend
//
// Native Anthropic wire format for direct API access. Key advantages
// over the OpenAI-compat path:
// - Prompt caching (90% cost reduction on repeated prefixes)
// - No middleman (OpenRouter) — cleaner error handling
// - Native tool use and thinking support
//
// Message format conversion happens at the boundary: internal Message
// types are converted to Anthropic content blocks on send, and
// Anthropic streaming events are converted back to internal types.

// config.rs — Configuration and context loading

// Loads configuration from three layers (later overrides earlier):
// 1. Compiled defaults (AppConfig::default())
// 2. JSON5 config file (~/.config/poc-agent/config.json5)
// 3. CLI arguments
//
// Prompt assembly is split into two parts:
//
// - system_prompt: Short (~1K chars) — agent identity, tool instructions,
// behavioral norms. Sent as the system message with every API call.
//
// - context_message: Long — CLAUDE.md files + memory files + manifest.
// Sent as the first user message once per session. This is the identity
// layer — same files, same prompt, different model = same person.
//
// The split matters because long system prompts degrade tool-calling
// behavior on models like Qwen 3.5 (documented: >8K chars causes
// degradation). By keeping the system prompt short and putting identity
// context in a user message, we get reliable tool use AND full identity.

// the model waiting for user input is a conscious action (calling
// yield_to_user), not the default.

// This inverts the tool-chaining problem: instead of needing the
// model to sustain multi-step chains (hard, model-dependent), the
// DMN provides continuation externally. The model takes one step
// at a time. The DMN handles "and then what?"
//
// Named after the brain's default mode network — the always-on
// background process for autobiographical memory, future planning,
// and creative insight. The biological DMN isn't the thinking itself
// — it's the tonic firing that keeps the cortex warm enough to
// think. Our DMN is the ARAS for the agent: it doesn't decide

// merge-logs: Recover historical entries from a checkpoint log and merge
// with the current log into a NEW output file.
//
// This tool was written to recover history destroyed by rewrite_store()
// (see persist.rs comment). It reads two capnp node logs, finds entries
// in the old log that don't exist in the current log (by uuid+version),
// and writes a merged log containing both.
//
// SAFETY: This tool never modifies either input file. The merged output
// goes to a new directory specified by the user.
//
// Usage:
// merge-logs <old_log> <current_log> <output_dir>
//
// Example:
// merge-logs ~/.claude/memory/checkpoints/nodes.capnp \
// ~/.claude/memory/nodes.capnp \
// /tmp/merged-store
