Summary

This PR adds cross-solver option aliases to enable interchangeable option names across all 5 solvers (Ipopt, Knitro, MadNCL, MadNLP, Uno). Users can now use any solver's option names with any other solver, making the API more consistent and user-friendly.

Features

Cross-Solver Aliases Added

Maximum iterations - All 5 solvers now support:

• :max_iter (canonical in Ipopt, MadNCL, MadNLP)
• :maxit (canonical in Knitro) ← NEW
• :maxiter, :max_iterations (existing aliases)

Maximum wall time - All 5 solvers now support:

• :max_wall_time (canonical in Ipopt, MadNCL, MadNLP)
• :maxtime (canonical in Knitro) ← NEW
• :max_time (existing alias in MadNCL/MadNLP) ← NEW
• :time_limit (canonical in Uno) ← NEW

Acceptable tolerance - 3 solvers now support:

• :acceptable_tol (canonical in Ipopt, MadNCL, MadNLP)
• :acc_tol (existing alias in MadNCL/MadNLP) ← NEW for Ipopt

Implementation

• StrategyOptions: Added alias_map field for O(1) alias resolution
• build_strategy_options: Constructs alias map from strategy metadata
• Access methods: getindex, haskey, option now resolve aliases automatically
• Preservation: Aliases remain accessible after solver construction

Examples

# Before: Different names per solver
ipopt = Solvers.Ipopt(max_iter=500, max_wall_time=3600.0)
knitro = Solvers.Knitro(maxit=500, maxtime=3600.0)  
uno = Solvers.Uno(max_iterations=500, time_limit=3600.0)

# After: Any names work with any solver
ipopt = Solvers.Ipopt(maxit=500, maxtime=3600.0)  # Knitro names with Ipopt
knitro = Solvers.Knitro(max_iter=500, max_wall_time=3600.0)  # Ipopt names with Knitro
uno = Solvers.Uno(maxit=500, max_wall_time=3600.0)  # Mixed names with Uno

# Access via any alias after construction
opts = ipopt.options
opts[:maxit]        # ✅ 500 (Knitro name)
opts[:maxtime]      # ✅ 3600.0 (Knitro name)  
opts[:time_limit]   # ✅ 3600.0 (Uno name)
