Pull #17

github

Add a recipes guide, usage-rules.md and clearer compile errors

Compile errors for the likely mistakes now show the right form:
- {:ok, user} <- fetch(id), the with habit, points at user <- fetch(id)
- other patterns on the left of a step explain that a step is named by
  a single variable
- run/put/let/inspect calls inside a block no longer say "since Q 2.0";
  they and Q.run(...) style calls point at bindings, and at the
  functional API for a step per item

guides/recipes.md collects complete patterns with failure and cleanup
paths: matching errors by step, boolean checks, optional steps, cache
halts, undoing steps, per-item steps (flat and as a child queue),
reusable step groups, using results on success, and testing. Each
recipe was run against stub services.

usage-rules.md is a short list of rules and common mistakes for coding
agents. Both ship in the hex package and appear in the docs; the README
links them.
