Add configurable HTTP timeout for Bun and Tailwind CLI downloads

[ashuklaa]

Exposes the HTTP request timeout used when downloading Bun and Tailwind as a cli flag and a toml config option under [tools.lustre.bin].

Fixes #149

Changes

• Added flag read functionality that pulls timeout from cli flags primarily with the user’s gleam.toml [tools.lustre.bin].timeout as the secondary location, defaulting to 60000ms if neither are present.
• Updated Bun and Tailwind download functions to call httpc.timeout(timeout) using this value.
• Documented timeout flag in the TOML reference.

Testing Methodology
Created a small Gleam project with lustre_dev_tools as a local dev-dependency.

Added to gleam.toml:
[tools.lustre.bin]
timeout = 120000

Ran:
gleam run -m lustre/dev add tailwind

gleam run -m lustre/dev add bun

Confirmed that configured timeout value was used by testing with timeout = 10, received ResponseTimeout error as expected:

Thank you for this! Do you think you could use the approach that other config options are using by using the cli module: that way we'd get a command-line flag for free too :)

Could we also name the option just timeout!

Sure, no worries! This was my first shot at an open source contribution so I appreciate your patience.

I read through the flag config for build and start and redid my implementation through the cli module, and tested to ensure that toml and cli flag based configs were respected:

I also found that the download function for bun/tailwind was being used by the build and watcher functions so those now also respect toml based timeout flags.

Let me know if there are further changes required!

Hi @hayleigh-dot-dev just realized I forgot to follow up on this and ask if there were any further enhancements needed but just checking in! Happy holidays!

Resolved concerns regarding timeout logic, switching to seconds-level control instead of ms, and removed verbose console logging

Looks wicked, thank you!
