feat(ucalc): test vector generation command (testvec) (#661)

* feat(ucalc): test vector generation command (#633)

Add `testvec <type> <function> [a, b, n]` that generates golden
reference test vectors for regression tests.

Output formats:
- Plain (default): C++ constexpr initializer list, directly pasteable
  into test code
- --json: structured JSON with input/value/decimal/binary per entry
- --csv: tabular with header row
- --quiet: input-value pairs

Example:
  ucalc testvec posit16 sin [0, 3.14159, 5]
  // Golden reference vectors for sin(x) in posit< 16, 2, uint16_t>
  struct TestVector { double input; double expected; };
  constexpr TestVector sin_posit16[] = {
      { 0, 0 },  // 0.0000e+00
      { 0.785397, 0.707031 },  // 7.0703e-01
      ...
  };

Resolves #633

* fix(ucalc): use variable binding instead of std::to_string in testvec

std::to_string(x) truncates to 6 decimal digits, causing input/output
mismatch. Now binds x as a variable into the evaluator (same pattern
as sweep) so the full double-precision value is used for evaluation.
