Redesign the rendering pipeline so that presentation logic lives in Typst template files rather than compiled Rust code, thus enabling user-defined templates written in Typst. This continues and supersedes #88. Adapters are refactored to emit a Typst literal, and templates are reinterpreted to mean a Typst file which supplies a render() function which, when given an appropriate domain-specific literal, is renders out the appropriate layout. Every domain has an Adapter which projects from the parser's internal AST to a set of types that are domain-specific. These are denormalized and suitable for being used by a template. These domain-specific objects are then serialized out as a Typst literal. This literal can then be used by a Template. Each domain has a default built in, but the `--template` command-line option allows the user to specify their own Typst file to handle the rendering.

Refactor the machinery orchestrating rendering at the top-level. Change the --output option of technique render to select between writing PDF and writing Typst markup (for debugging). Articulate a new Template trait and add a new --template option to the technique render command, with use
sourceas the current default.Templates are composed of two phases. First there is an "adapter" which takes the abstract syntax tree from the parser and projects it into a set of types suitable to the domain being modelled, and then there is a "renderer" which provides a custom implementation of transforming those domain objects into Typst markup.
Two templates are provided with _very+ preliminary implementations: a
checklistone, meant for simple todo lists, and aprocedureone, which presents an operations plan written in Technique with full fidelity.Bumps the major version to
0.5.
