Detailed Description

Implements the OP_TRY_PUSH opcode to begin a try/catch region.

This file handles the OP_TRY_PUSH instruction, which marks the start of a try/catch region in the current frame by pushing the index of the TRY instruction onto a small per-frame stack. The actual catch target IP is stored in the TRY instruction's operand and may be patched later by the compiler/linker.

Behavior:

• Pushes the index of this TRY instruction (f->ip - 1) onto f->try_stack.
• Does not modify the value stack.

Errors:

• If the try depth exceeds the size of f->try_stack, prints a runtime error and terminates the process.
