start-native.bat

@echo off
REM Kimi Code launcher with native Rust tools built.
REM Usage:
REM   start-native.bat               - Run Bun CLI with native Rust tools
REM   start-native.bat --pure-rust   - Run pure Rust standalone REPL binary (kimi-agent-cli)
REM   start-native.bat --web         - Run Web UI powered by native Rust server (kimi-agent --serve)

REM `shift` never updates `%*`, so rebuild the argument list after consuming the
REM launcher flags; otherwise `--web` / `--pure-rust` leak into the CLI parser.
REM The flags are recognised in any position, so `--model X --web` works the same
REM as `--web --model X`.
REM The accumulator is written without the `set "VAR=..."` wrapper on purpose:
REM that wrapper pairs its own quotes with the ones around `%~1`, which leaves
REM `&`, `|`, `<` and `>` inside an argument unquoted -- the line then splits and
REM the argument is silently dropped.
