chore(scripts): remove tool_call aliases and legacy tool discovery

These 4 scripts are redundant aliases and a tool that uses a
non-canonical MCP API path.

Removed (4 files, ~3.5 KB):
- scan_all_hints.py (2.0 KB) - only referenced in
  .claude/commands/mma-tier2-tech-lead.md (local AI tool config,
  not the project). The MMA workflow uses audit_weak_types.py.
- tool_call.bat (49 B) - cmd wrapper for tool_call.py
  (redundant with tool_call.ps1)
- tool_call.cmd (50 B) - cmd wrapper for tool_call.py
  (redundant with tool_call.ps1)
- tool_discovery.py (1.4 KB) - tool spec discovery using the
  legacy mcp_client.MCP_TOOL_SPECS API path (will be refactored
  by mcp_architecture_refactor_20260606)

Kept tool-call bridge: tool_call.cpp (source), tool_call.exe
(binary), tool_call.py (Python bridge), tool_call.ps1 (PowerShell).
