feat: send editor context (visible files, open tabs, shell, timezone) to CLI backend

[markijbema]

Summary

Send editor context information (visible files, open tabs, active file, shell, timezone) alongside chat messages to the CLI backend.

Changes

• EditorContext interface added to src/services/cli-backend/types.ts — defines the shape of editor context data (visible files, open tabs, active file, shell, timezone, cwd)
• sendMessage() in http-client.ts extended to accept and forward an optional editorContext parameter to the CLI backend
• gatherEditorContext() in KiloProvider.ts — new method that collects:
  • Visible text editor file paths
  • Open tab file paths
  • Active file path
  • Default shell from VS Code terminal profile
  • User timezone (via Intl.DateTimeFormat)
  • Workspace root as cwd
• All paths are workspace-relative; files outside the workspace are excluded
• Existing active editor file:// URI injection into the message body is preserved for backward compatibility
• Includes docs/vscode-context-plan.md design document

Context

Implements the extension-side pieces of Phase 1 + Phase 2 from docs/vscode-context-plan.md. The CLI backend side (consuming the context) is tracked separately.

Remove full file

don't send the full open editor, as the agent will interpret that as part of the prompt, no wi can say hello to the agent again without the agent starting work on the todo immediately

WARNING: Timezone offset mismatch — getTimezoneOffset() returns the server/CLI process local offset, not the offset for the user's timezone string.

When the CLI backend runs in a different timezone than the VS Code client (e.g., remote dev server in UTC, user in Europe/Amsterdam), the displayed offset will be wrong while the timezone name is correct.

To compute the correct offset from the timezone string, you could use Intl.DateTimeFormat:

function getUtcOffset(timezone: string): string {
  const now = new Date()
  const formatter = new Intl.DateTimeFormat("en-US", {
    timeZone: timezone,
    timeZoneName: "shortOffset",
  })
  const parts = formatter.formatToParts(now)
  const tzPart = parts.find((p) => p.type === "timeZoneName")
  return tzPart?.value ?? ""
}

Or simply omit the computed offset and just display the timezone name, since the name is authoritative.

SUGGESTION: The old ignoreController is replaced but never disposed when the workspace directory changes. This leaks the previous controller's internal state (loaded contents, realpath cache).

Consider disposing the old controller before replacing it:

this.ignoreController?.dispose()

before assigning the new one.

SUGGESTION: Orphaned JSDoc comment — this doc block ("Gather VS Code editor context...") was likely intended for gatherEditorContext() at line 1527, but it's now attached to nothing since getIgnoreController() has its own JSDoc immediately below. Consider removing this block or moving it above gatherEditorContext().
