Board search and filter

Summary

Add a text filter input and an archived show/hide toggle to the kanban board. The filter matches cards by title, name, or token across all columns. The archived toggle hides/shows the archived column. Pure frontend change — no backend modifications.

Motivation

When a project accumulates 20+ changes across the six lifecycle columns (ideas, draft, todo, in_progress, done, archived), finding a specific change requires visually scanning all columns. A text filter and archived toggle make the board usable at scale.

Design

Frontend (dashboard/dist/index.js)

Add a filterText state variable and an showArchived boolean (default: true) to the Board component. Add a filter Input and an archived toggle button to the board header (between the repo name and the columns). Filter byCol entries before rendering: a card passes if its title, name, or token contains the filter text (case-insensitive). When showArchived is false, the archived column is hidden entirely.

Hash interaction

When a hash token is present in the URL, bypass the filter for that specific item — clear the filter or exclude the hash-matched card from filtering so the detail dialog can open.

Alternatives considered

• Per-column checkboxes. Rejected — too much UI for a dense toolbar. The archived show/hide toggle covers the main use case.
• Server-side filtering. Rejected — the board payload is already fully loaded. Client-side is simpler and instant.
