v0.8.2-fork.1

Added

• Added herdr session kill <name> and the opt-in keys.kill_session action to stop and permanently delete the current named session after confirmation. The default session remains protected.
• With exactly two panes, the shared divider now accents the half beside the focused pane.

Changed

• The expanded sidebar header now shows the active session name, and session snapshots expose it as name.
• Entering a linked Git worktree in a space's root pane now opens the primary checkout as its parent space while keeping the linked worktree focused.
• Spaces now group under the repository they belong to, so worktrees created outside Herdr and several spaces on one checkout share a single group.
• Grouped rows now show their checkout name alongside the branch and ahead/behind counts instead of replacing the name with the branch.

Fixed

• Fixed a panic on builds whose version carries a prerelease suffix, which killed the server whenever a plugin manifest was loaded.
