2026-06-07	Add public.zig as the libpanto root; delete root.zig	t
	public.zig is now the sole exported root (build.zig points the panto module at it). It defines the curated public API allowlist: behavioral facades (Agent/Stream/Conversation wrapping a pointer to the heap-pinned internal), the ResultParts struct, Pricing, the session seam, and data-type aliases for the Config/Conversation/Event families. A clearly-marked transitional block re-exports the internal module namespaces and the freestanding result-part helpers the panto CLI still imports directly; Phase 4 trims these as the CLI migrates onto the curated surface. Stream.Phase is now pub so State can alias it. The refAllDecls test contract moved from root.zig into public.zig.
2026-06-07	R2: redesign session store with wire-format identity	t
	Replace the single-session SessionManager seam with a directory-backed catalog. session_manager.zig -> file_system_jsonl_store.zig; the old machinery becomes internal SessionFile, and a new FileSystemJSONLStore implements the redesigned SessionStore vtable (create/list/resolve/latest/ load/appendMessages) minting Session/SessionInfo handles. Session logs now record wire-format provider identity ({api_style, base_url, model, reasoning}) instead of a single provider string or CLI aliases; no api_key material is ever stored. Disk* content types renamed Stored*; the rich audit-oriented write record is PersistentMessage (in-memory Message + WireIdentity + provenance). Agent.init now takes a Session; persist_provider/persist_model display strings deleted (banner stays alias-based, resume picks default model). Message.metadata round-trips. Dangling-prompt recovery dropped. CLI migrated to the catalog store for run/resume/list. Clean break, no version bump (old logs wiped).
