* bring in shell impl

* add `$` to global bun scope

* Expose shell parse func on debug mode

* Expose lex tokens and add tests

* refactor parser to have better ast

* assigns and export

* pipeline kinda working

* Decouple Subprocess spawning code from JS stuff

* Subprocess works!

* Conditional execution

* Support JS objects in template expression

* More complete redirection

* Properly drain stdin/stdout/stderr and fix crash from deallocating JSC memory

* Return errors in parser

* Support command substitution

* wip brace expansion stuff

* Rearrange some files

* expansion wip

* Brace expansion working

* wip brace expansion

* refactor brace algorithm

* wip brace expansion on shell

* fix brace expansion

* Working nested brace expansion!

* brace expansion in shell variable assignment only set the last expanded

* stuff

* Small little perf things

* benchmark and test and stuff

* stuff

* fix nested braces but its also kinda broken

* attempt to fix complicated nested braces

* test

* Use fast tokenized algorithm for non nested braces, use parsed algorithm for nested braces

* fix nested braces one and for all

* small stuff

* Not sure if that made a difference

* revert that

* good speed optimization

* rip

* Environment variables, builtin/native shell cmds

* Fix tests

* Support `cd`, `pwd`, add boilerplate for glob expansion

* Support `which`

* Support `rm`

* wip

* wip

* escaping and abstract shell char iterator

* strpool unicode

* Brace expansion support unicode, disallow invalid surrogates in shell script

* shell choose ascii or unicode lexer depending on input

* fix bugs write tests

* kinda start async stuff

* HOLY SHIT big refactor of Subprocess

woops forget to commit this

...and this

* HOLY MOLY it works

* Refactor some stuff, start eval word expansion

* interpret all the nodes

* stuff

* stuff

* stuff

* kind of works but doesnt

* Buffered output works

* no need to heap allocate autosizer

* Fix bug

* Fix some stuff

* unprotect

* move out dummy shell thing

* Bring back assignments

* create expansion state so it can be non blocking for expansions that need IO (glob, cmd subst)

* glob back in action

* Setup builtin non blocking IO commands and implement export

big issue is control flow is really fcked up here need to fix that

* make Cmd state machine use a loop so control flow is a bit more clear

* rename stuff

* move that

* Implement the echo builtin again

* implement cd again but non blocking io

* Fix ls and use proper write function to prevent blockign writes

* Implement which

* holy moly big port std.fs.deleteTree

* fix compile errors

* Okay that works

* rm works thatsnice

* damn

* split it out

* rm async implementation

* fix rm bug for nested

* prevent root from being deleted

* rm error handling

* oops

* pwd and fix some script exec bug

* Implement `mv`

* stub out mv to work accross filesystems

* move it around

* woops

* boilerplate for ls and options

* more boilerplate

* stuff

* that got lost in merge

* upgrade shell stuff zig 0.12.0-dev.1828+225fe6ddb

* Implement basic ls

* smol cleanup

* Fix stream, response redirect stdin

* No longer need spawn to be abstract

* Custom promise

* move around some stuff

* shell promise returns shell output

* make tht work for builtins

* refactor IO abstractions to work with JS or mini event loop

* woops

* scaffolding for refactor

* refactor builtins to make event loop refactor easier

* Fix parsing edge case on assignments, fix expansion on cmd assignments

* change subproc to work with any event loop

* Finish refactoring subproc

* move global abstraction out

* big refactor boys

* holy moly: integrate into cli and fix allll the compile errors

* okay works in bun run now

* actually tick the event loop lol

* Fix more stuff

* Support comments

* Fix some tests

* delete that

* Properly report errors when failing to spawn command

* fix `rm -d`

* fix `rm -d`

* Fix boolean logic

* error on subshells (e.g. `true && (echo hi && echo lol)`)

* Move out shell state from interpreter struct

* Cmd substitution supports arbitrary script, not just a single cmd

* Some escaping/quotation tests

* Fix stuff add more tests:

- cmd substitution quotations
- escape backticks in single quots

* ALOT of stuff:

- fix proper subshell inheritance of env for cmd subst
- fix: was wrong, assignments don't run in subshell in conditionals
- fix lexing chained vars `$VAR$VAR`
- more tests

* Fix subtle bugs

* Fix crazy redirect to arraybuffer bug

* more crazy echo edgecases

* Proper lexer errors instead of just panicking lol

* yoops

* Proper parsing errors

* Errors for bun run shell script

* Fix redirecting to file

* More test fix bugs yay

* Fix redirect on builtins

* Open redirection fds with O_TRUNC

* Fix lexing invalid variables and add ability to change cwd from JS api

* yoops

* Fix `.cwd()`

* `$PWD` and fix redirection bugs

* Get rid of  some `FIXME`s

* throw errors in some places instead of panicking

* Print some errors to stderr

* Get rid of some more panics again

* Handle errors on glob
