feat(ucalc): provenance tracking on AST nodes (#672)

* docs(ucalc): AST evaluator conversion plan for Epic #642

Plan for converting the expression evaluator to AST-based with
provenance tracking, rewrite pattern database, and structural
pattern matching. Five phases, each delivering standalone value.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat(ucalc): provenance tracking on AST nodes (#667)

Add Provenance enum (exact/computed) to ASTNode. Leaf nodes (Literal,
Variable, Constant) are tagged exact. Operation nodes (BinaryOp,
UnaryOp, FunctionCall) are tagged computed.

Provenance displayed in ast command output:
  `-- op:- [computed]
      |-- fn:sqrt [computed]
      |   `-- var:a [exact]
      `-- fn:sqrt [computed]
          `-- var:b [exact]

This enables the cancel command (future Phase 4) to distinguish
actionable cancellation (exact inputs, fixable by rewrite) from
inherent cancellation (computed intermediates).

JSON output includes "provenance" field on every AST node.

Resolves #667
