NCBM 729627eee9 docs: spell out the turn and round model

doc/turns-and-rounds.md defines the two nested units the loop is built on: a round is one request→response plus the tool batch it asked for, a turn is one user message through the explicit stop (0..N rounds), and a session is a stored sequence of turns. It records what bounds each unit (max_rounds, truncation continues, retries), which work is round-scoped (request assembly, context reduction, the aggregated soft confirm) and which state resets per turn (read-before-edit, yyy auto-continue, /yolo once, the todo touched flag, usage totals) versus what outlives it (rows, todo stack, grants, reminder bands).

Linked from the architecture doc, with the short version in AGENTS.md.

plyngent
- typedef: Shared type aliases.
- lmproto: Protocols for interacting with LLM service.
  - (common)
    - model: Messages models of specified providers.
    - config: Configurations for specified providers.
    - client: Clients for accessing existent specified services.
    - server: Servers for accepting other clients.
  - openai_compatible: Chat Completions base (kind=chat_completions).
  - openai: Platform Responses + chat (kind=responses).
  - anthropic: Messages API (kind=messages).
  - deepseek
    - openai_compat (kind=chat_completions)
    - responses (kind=responses; DeepSeek Responses API)
    - anthropic (kind=messages; DeepSeek Anthropic-compatible API on https://api.deepseek.com/anthropic)
- utils: Common utilities for code architecture.
  - components: Utilities for class composition.
- memory: Storage controlling for sessions and messages.
- config: Plyngent configuration center (TOML), including [plugins] and [networking] (e.g. fetch SSRF Fake-IP CIDR exemptions). Model entries may override provider preset / url for mixed API routing. [skills] holds the skill roots, discovery sources, catalog limits, and the standing write grant.
- runtime: create_client maps effective provider preset → protocol client.
- skills: Skill discovery (ordered roots, SKILL.md frontmatter subset, mtime-cached store) and the read/write path rules the tools use.
- agent: Kind-based tool loop, streaming, usage, compact; bridges: responses_bridge/responses_dispatch, messages_bridge/messages_dispatch; @tool / tags / registry. History stays chat-completions-shaped.
- tools: Workspace file/process/VCS/chat/todo/net/skill tools + directory-access grants (access); catalog; plugins; instance/session context and views.
- prompting: Shared ask/choose/form for CLI and tools.
- cli: Click entry, slash registry, REPL, one-shot chat.
- web: Web service (Phase H; not implemented).

Plugins (third-party entry points, allowlisted under [plugins]): plugins.md. Conversation units (a round = one request→response plus its tool batch, a turn = a user message to the explicit stop): turns-and-rounds.md.
