Add two new flags for the `easycrypt` CLI to support LLM coding agents: - `-upto <pos>`: compile up to a given position and print goals there - `-lastgoals`: print the last unproven goals Also add a dedicated `llm` command mode and an LLM agent guide (doc/llm/CLAUDE.md) documenting EasyCrypt tactics and workflow for use with AI coding assistants.
Allow rewrite patterns to designate a subterm inside a larger context with the [x in pattern] syntax. This lets rewrite target exactly the occurrence named by the surrounding context, and adds regression coverage for that form. The context variable must appear exactly once in the pattern (linearity check). Delta expansion and conversion are disabled during contextual pattern matching to ensure position computation remains sound.

Non-rewriting should be enforced more strictly to try to reduce future breaks. Maybe refactor into separate helper function to contain dependency?
