Description

This PR introduces initial Start Work flow that:

• adds a "Start Work" shortcut to the home view
• lets user to select a GitHub issue and then starts a create-branch flow
• suggests the repository of the selected issue as default repository for creating a branch
• suggests a default branch name based on issue title

Mostly nitpicks - the only major suggestion would be to set up a provider that manages the issue querying and includes caching and error handling as we have with Launchpad. Most of this would be for future-proofing purposes - we don't automatically query for issues with this feature like we do for Launchpad - but the need for that may arise sooner than we think (for example - some UX on the Home view showing a count of how many issues we have, etc.)

[axosoft-ramint]

Nitpick, but we might want to mention worktrees in here somehow since this flow will, most likely, at least heavily encourage creating one.

Might want to follow up with @justinrobots if you haven't already since I think there was some confusion on whether this gating applies to "Start Work" the same way it does for Launchpad.

I put the 'beaker' icon as a placeholder in my WIP, but we should probably check in with the team on what would make a good representative icon for this feature in general, as well as for actions like this.

[axosoft-ramint]

Perhaps we can do one of the following:

1. Create a startWorkProvider
2. Rename the launchpadProvider to be a bit more flexible outside the domain of Launchpad itself and extend it

And then we can add functions to the provider to:

1. Get searched issues, with caching and error handling like we do for Launchpad items, and the ability to filter out stale ones and other post-processing like we do with PRs for Launchpad (not that we have to implement any post-processing now, just the caching and error handling parts)
2. Complete actions on "start work" items, like creating a branch, etc.
3. Set up other utilities that we want in the future for Start Work so that the command file doesn't get out of hand.
4. Use those functions here as needed, like launchpad does with launchpadProvider.

Please review it one more time. All notes related to implementing a provider haven't been fixed yet, because I've been focusing on the functionality and Eric has suggested to implement optimizations as a follow-up.

So, now you're welcome to suggest any urgent fixes that I can make on Monday.

@sergeibbb I assume you mean @eamodio instead of me, right?

True. Sorry for bothering

5. (in the pre-release, if I click the globe to open a Launchpad PR in the browser, the quickpick stays open).

disappears for me in pre-releas. It disappears every time when the window looses the focus, but it stays if (and after) the quickpick has a text in the search field.

But I agree that Start Work is different from Launchpad. After typing something in the search field and clicking the globe: Launchpad stays, but Start Work disappears. I'm going to fix it.

Some of the issues from previous review may be due to debugging or pre-existing regressions. We will address those and any other unaddressed issues above post-merge.
