v0.7.1

The confirmation before move_money and set_category_budget now says what the category will have available, signed, wherever that differs from what is budgeted (#157). get_spending_trends reads the months up to the current one instead of months budgeted ahead (#151), and reconcile_account looks for duplicates from the plan's day rather than the machine's clock (#161).

Security: fastmcp 4.1.2 (#154), and every lock file in the repository is now audited in CI (#160). avenir-mcp can also run in a container, from a Dockerfile at the root (#158).

The README now starts with the install and what you can ask, with a new demo (#155); tool descriptions explain their parameters and point to the right sibling tool (#153).

No change to tool names or arguments. See CHANGELOG.md.
