feat: POST /memory/learn endpoint + refactor mem learn CLI

Learning flow now goes through the service, not local JSONL:
- POST /memory/learn: accepts markdown, chunks it, runs gated loop
  (LLM evaluates + compacts), stores in pgvector. OpenAI-style API.
- mem learn CLI: reads files, calls POST /memory/learn per file
- Removed cmd_compact (gated loop IS the compaction)
- Updated README with new commands and API docs

Memory never grows unbounded — every update is a rewrite, not append.
The gated loop LLM acts as evaluator + compactor in one pass.

+### Learning Flow
+
+```
+Agent/CLI → POST /memory/learn → chunk markdown → gated loop:
+  For each chunk:
+    LLM evaluates: does this add new knowledge? (update gate)
+    If yes → LLM rewrites memory incorporating new fact (compaction)
+    If no → chunk rejected, memory unchanged
+  → Store compacted memory in pgvector (embedded, searchable)
+  → Return {chunks_seen, chunks_used, memory, stored}
+```
+
+Memory never grows unbounded — every update is a rewrite, not an append.
+The LLM acts as both evaluator and compactor in one pass.
