Tianyi Cui 066f94c7e0 docs: unwrap hard-wrapped Markdown to one line per paragraph

Hard line breaks mid-paragraph make docs harder to edit and diff — a
one-word change reflows and re-diffs the whole paragraph. Reflow all
tracked non-vendor Markdown (plus vendor/AGENTS.md) so each prose
paragraph is a single line; soft-wrapping is the editor's job. Fenced
code, tables, and list structure are preserved (wrapped list items fold
to one line per bullet). Documents the convention in AGENTS.md.

echo-agent

Runnable demo: stdin chat with a scripted mock model and an echo tool.

What it shows

A complete Cordis app loaded from cordis.yml — the standard "stack of plugins" pattern
mock-llm.ts — a mock LlmAdapter that streams scripted responses and calls the echo tool when the user types "echo "
echo-tool.ts — a tool registered via ctx.tools.register() that echoes text back uppercased
session-jsonl.ts — a minimal persistence plugin: write-behind buffering of session/event notifications, drained to a JSONL file at session/flush
stdio-chat.ts — a minimal UI plugin: reads stdin lines and send/steers the agent, renders stream deltas, tool calls, and tool results

Plugin files

File	Role	Key patterns demonstrated
`mock-llm.ts`	`LlmAdapter` registration	`ctx.llm.registerAdapter(['mock-echo'], …)`, streaming chunks with proper `block-start`/`block-end` protocol
`echo-tool.ts`	Tool registration	`ctx.tools.register(defineTool(…))` with typed `execute` args, tool execution returning `ContentBlock[]`
`session-jsonl.ts`	Persistence	`session/event` listener + `session/flush` drain, fiber-dispose cleanup
`stdio-chat.ts`	UI	`agent/stream-chunk`, `session/event` (tool/*), stdin→send/steer
`start.ts`	Bootstrap	`Context` + `Loader` + `plugin-include` wired to `cordis.yml`

Run

yarn demo
# or:
node --expose-internals --import tsx examples/echo-agent/start.ts

Type a message and press Enter. "echo " triggers a tool call round-trip (the mock model requests the echo tool, which echoes the text uppercased, and the next model step acknowledges it).

The session is persisted to <session-id>.jsonl in the examples/echo-agent/ directory. Clean up with: rm -f examples/echo-agent/*.jsonl
