[Ongoing] Reduce Package Size

[aklinker1]

Feature Request

This is an ongoing ticket around reducing the size of WXT. WXT alone is only 760kb. However, when including all it's dependencies, it's 110mb. I'd like to reduce that number.

https://pkg-size.dev/wxt (sort by "Package Size" or "Dependency Size" for best view IMO)

Some ideas:

• perf: Downgrade esbuild so a single version is shared between sub-dependencies #1045 (~20mb)
• Replace execa with nano-spawn #1037
• Minimize publish-browser-extension, another repo I own (~1mb)
• Stay inside the unjs ecosystem when possible
• Write custom version of web-ext - I already have a fork, web-ext-run, that's smaller (65mb → 26mb). Not sure if I want to start maintaining this... But if we did, we could make firefox support a separate package you have to install, making types much smaller.
• chore: shrink down on dependencies #1050
