feat: add config option for sidebar default state#6955

[themarcel]

Adds a new tui.sidebar config option to set the sidebar's initial state. Accepts "auto" (default), "show", or "hide".

• Config provides initial default before user interaction
• User toggles via keybind are stored in KV and take precedence
• Priority: KV store > config.tui.sidebar > "auto"

Reopening of #6955
Closes #3682

  • feat: add persistent sidebar overlay toggle in command palette (resolves #6086) #6093
  • Why it's related: Also deals with sidebar UI state management, though it appears to focus on command palette toggle functionality rather than config-based default state

The current PR (23137) is a reopening of the original #6955 for the sidebar config feature. The search results primarily return this PR itself and one other sidebar-related feature. The feature appears to be novel—adding a config option for sidebar default state with KV store precedence is distinct from the persistent toggle functionality in PR #6093.
