fix(coverage+validation): C2/C3 script gate, V1/V2/V4 JSON/XML errors, I2/I3/I4 tests

C2: Fix coverage.sh — remove || true from lcov capture/extract steps so real
    lcov failures are visible; empty coverage.info now exits with code 3.
C3: Add coverage gate to quality-gates CI job (SKIP_COVERAGE_GATE=1 ramp-up
    mode until I5 is resolved — fast suite covers ~9.6% not 80%). Thresholds:
    80% line / 70% branch / 90% function (agreed 2026-05-31).

V1: Wrap JSON parse + field extraction in try/catch — nlohmann parse_error and
    type_error now surface as std::runtime_error with the file path.
V2: Wrap stoi/stod in XML Solver parser — missing/non-numeric attributes throw
    std::runtime_error instead of leaking std::invalid_argument.
V4: Validate required JSON keys (dof_vector, solver, solver.*) before access —
    missing field produces a clear named-field error message.

I2: 6 serialization negative tests (missing file, malformed JSON, missing
    dof_vector, missing solver block, missing XML file, non-numeric XML attr).
I3: load_mesh throws on non-triangulated (quad) mesh — covers the
    is_triangle_mesh guard that was previously untested.
I4: spherical_hessian throws on edge DOFs — covers the logic_error guard.

290/290 tests pass (+8 new).
