fix: improve hidden index tree item visibility and menu actions

[lte-z]

Fixes #656

Changes

This PR improves hidden index visibility and context menu behavior in the tree view.

Tree item updates

• Added hidden/default state segments to IndexItem context values
• Added a hidden description for hidden indexes in the tree view

Context menu updates

Updated menu when clauses so only valid actions are shown:

• Hidden indexes show only "Unhide Index…"
• Non-hidden indexes show only "Hide Index…"
• _id_ indexes show neither action

Behavior

Hidden indexes

• Display hidden next to the index name in the tree
• Show only "Unhide Index…" in the context menu

Regular indexes

• Show only "Hide Index…" in the context menu

_id_ index

• Does not show hide/unhide actions

Screenshots

id index

Regular and hidden indexes

Notes

• Tooltip behavior remains unchanged
• Uses createContextValue() to compose index state context segments

Note

Copilot was unable to run its full agentic suite in this review.

Adds richer context and UI cues for DocumentDB index tree items so the Hide/Unhide Index commands only appear when appropriate (e.g., not for default _id_ indexes, and toggling based on hidden state).

Changes:

• Add index_hidden / index_default context values and show a “hidden” description for hidden indexes in the tree.
• Update command when clauses to hide/show Hide/Unhide actions based on those context values.
