v0.9.1

• Simple variable declarations no longer require a trailing semicolon: typing int i = 0 and pressing Enter now auto-inserts a semicolon (#499).
• Improved NuGet installation output, using a Spectre.Console status display with log lines rendered above it (#500).
• Autocomplete menu: replaced the colored unicode circles/squares with more meaningful characters like Ⓕ for fields and Ⓟ for properties, (#503).
• Reworked assembly and NuGet loading so that all references load through a single, dedicated AssemblyLoadContext. Fixes a class of assembly and nuget loading errors (#498).
• AI code-completion errors (for example network or HTTP failures) are now caught and surfaced as REPL feedback instead of crashing the REPL (#501).
