[CHORE] Commands optimizer

[Felienne]

A bit of performance detective work showed that the achievements code calls allCommands a lot, but allCommands actually parses the code, which is expensive.

A few more tweaks could be made:

• Fix the TODO "hacks" I made to get this done
• Optimize even further by parsing once, and passing the parse tree to allCommands instead of parsing twice
• If we expand the hypothesis testing, remove the allcommands call there too (it now parses twice)
