Add PrecisionCheckLevel enum (NONE/FUNCTION/MODULE) to GlobalEnv for fine-grained control of precision checking. Register backward hooks for both Function and Module levels to check gradients during backward pass. Key changes: - Add PrecisionCheckLevel to GlobalEnv with env var support (INFINI_PRECISION_CHECK=module/function) - Register backward pre/post hooks in Module::operator() on output tensor grad_fn - Register precision check hooks in Function::Apply based on precision level - Add HookHandle base class definition - Update Module::Forward call syntax from Forward() to operator() - Simplify CheckTensors output format 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
…te hook types - Replace environment variables (INFINI_PRECISION_CHECK, INFINI_PRECISION_CHECK_ALL_RANKS) with command-line flags (--precision_check, --precision_check_all_ranks) - Move hook type definitions from global scope into Function class to eliminate duplication between function.h and function_hook.h - Update GlobalEnv to accept precision check parameters and propagate through InitAllEnv - Update precision_checker to use GlobalEnv instead of getenv() - Add gflags definitions to gpt2 and llama3 examples - Fix module operator() calls to use correct syntax Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Add automatic precision checking for backward pass via INFINI_PRECISION_CHECK environment variable. Hooks are registered on gradient functions to detect NaN/Inf and monitor gradient statistics during backpropagation.
