* `"fs"` - Most of the arguments / validation

* `fs` - Rest of the arguments / validations

* Begin wiring up the `fs` module

* Fix all the build errors

* support printing typed arrays in console.log

* It...works?

* Support `require("fs")`, `import fs from 'fs';`, `import * as fs from 'fs'`

* Fix a couple bugs

* get rid of the crash reporter for now

* Update fs.exports.js

* [bun.js] slight improvement to startup time

* [bun.js] Improve error message printing

* [Bun.js] Add `Bun.gc()` to run the garbage collector manually and report heap size

* [Bun.js] Add Bun.generateHeapSnapshot to return what JS types are using memory

* [Bun.js] Add `Bun.shrink()` to tell JSC to shrink the VM size

* Improve encoding reader

* [bun.js] Improve callback & microtask performance

* Update node_fs.zig

* Implement `console.assert`

* simple test

* [Bun.js] Prepare for multiple globals/realms to support testing

* Create callbacks-overhead.mjs

* Update http.zig

* [Bun.js] Implement `queueMicrotask`

* Add test for queueMicrotask

* :sleepy:

* [Bun.js] Implement `process.versions`, `process.pid`, `process.ppid`, `process.nextTick`, `process.versions`,

* Implement `process.env.toJSON()`

* [Bun.js] Improve performance of `fs.existsSync`

* :nail_care:

* [Bun.js] Implement `process.chdir(str)` and `process.cwd()`, support up to 4 args in `process.nextTick`

* Reduce allocations in many places

* swap

* Make `bun` start 2ms faster

* Always use an apiLock()

* libBacktrace doesn't really work yet

* Fix crash in the upgrade checker

* Clean up code for importing the runtime when not bundling

* :camera:

* Update linker.zig

* 68!

* backtrace

* no, really backtrace

* Fix

* Linux fixes

* Fixes on Linux
