This commit adds exhaustive academic documentation covering the theoretical
foundations of the Anvomidav DSL for figure skating choreography notation.

## Formal Specification
- grammar.adoc: Complete EBNF grammar, lexical specification, parsing complexity
- semantics.adoc: Operational, denotational, and axiomatic semantics
- automata-theory.adoc: DFAs, PDAs, timed automata, tree automata

## Type Theory
- type-system.adoc: Dependent types, refinement types, effect system, linear types
- category-theory-foundations.adoc: CCCs, monads, adjunctions, fibred categories

## Domain Mathematics
- rink-geometry.adoc: Coordinate systems, paths, collision detection, topology

- skating-physics.adoc: Mechanics, dynamics, biomechanics
- numerical-analysis.adoc: Integration, error analysis, constraint handling

## Verification
- rules-specification.adoc: Formal ISU rule encoding
- verification-methodology.adoc: Theorem proving, model checking, runtime verification

Each document includes theorems, proofs (or proof sketches), definitions,
and clearly marked TODO sections for areas requiring further development.
