Add environment-aware new thread picker

[colonelpanic8]

What Changed

• Added a chat.newEnvironment command on Mod+Shift+N.
• Added a two-stage new-thread flow: choose an environment, then choose a project available on that environment.
• Presents every environment in one flat Run on list; the primary environment is labeled with its runtime hostname instead of Local.
• Keeps existing Mod+N project/context behavior unchanged.
• Migrates only the previous exact Mod+Shift+N chat.newLocal default while preserving custom chat.newLocal bindings.

Why

Thread creation previously collapsed projects across environments and silently selected one machine. This makes execution location explicit without treating local as a separate mode.

UI Changes

Environment selection:

Environment-scoped project selection:

Checklist

• Focused keybinding and environment-grouping tests pass (92 tests).
• Targeted formatting and lint checks pass.
• Integrated web verification covers environment -> project -> draft.
• Repository-wide vp check completes with only existing warnings outside this change.
• Repository-wide vp run typecheck is blocked by the existing interactive Astro dependency prompt and existing unrelated web type errors; changed packages/files introduce no reported type errors.

Note

Medium Risk
User-visible shortcut behavior changes for anyone on the old default binding, and thread creation now depends on environment shell bootstrap timing in the command palette.

Overview
Adds an environment-first way to start threads: Mod+Shift+N now binds to chat.newEnvironment and opens a “New thread on…” command palette flow (environment → projects on that machine). chat.newLocal is no longer the default on that shortcut; custom chat.newLocal bindings (e.g. other keys) are unchanged.

The palette gains a new-thread-on open intent, resolveNewThreadOnIntent to defer until environment shells load and close when no environments have projects, and buildSidebarProjectPickerEntries optional targetEnvironmentId so project lists don’t fall back to another environment’s copy of a repo.

Server startup migrates persisted configs that still have the exact legacy mod+shift+n → chat.newLocal rule to chat.newEnvironment, while leaving other chat.newLocal entries alone.

Note

Add environment-aware new thread picker triggered by chat.newEnvironment shortcut

• Adds a 'New thread on…' command palette flow that lets users pick an environment then a project when starting a new thread, bound to Shift+Mod+N by default.
• Introduces resolveNewThreadOnIntent to gate palette opening based on load state; the palette defers display until environment data is ready and closes if no targets exist.
• Extends buildSidebarProjectPickerEntries to accept an optional targetEnvironmentId, filtering project picker entries to a specific environment.
• Migrates the legacy mod+shift+n → chat.newLocal default keybinding to chat.newEnvironment on startup, leaving any user-defined chat.newLocal bindings intact.
• Behavioral Change: Shift+Mod+N now opens the environment picker instead of directly creating a local thread for users who had the previous default binding.

Deferred intent resets palette navigation

Medium Severity

The new-thread-on command palette flow can discard user selections. The palette displays "New thread on..." items before all environment shells are bootstrapped. If a user navigates into a submenu during this time, the openNewThreadOnFlow later clears the view stack, resetting their in-progress selection once bootstrapping completes.
