Board: fix redundant title control when primary field matches groupBy

[brylie]

Summary

• Closes Board/Calendar: primary field and groupBy can point at the same field, showing redundant controls #104: when a Collection's primaryFieldKey and Board's groupBy name the same select field, a card showed two separate editable controls for the identical value — the title PropertyValueCell and the "Move to column" <select>.
• UX decision (per the ux-designer skill's cross-surface-consistency principle, §6): keep the "Move to column" select as the single editable control in that case, falling back the title to the same plain non-editable label already used when there's no primary field at all.
• Calendar was inspected too and doesn't have this problem — its entry title is always plain, non-editable text (entryTitle()/primaryFieldDisplayValue), never a PropertyValueCell. No Calendar change was needed.
• Documented the resolved behavior in docs/specifications/collection-views.md §7.

Test plan

• Added a Board component test covering the collision case (title renders as plain text; exactly one editable control — the "Move to column" select — remains on the card)
• npm run test (1261 passed)
• npm run lint
• npm run check

Summary by CodeRabbit

• Bug Fixes

  • Board cards now use the resolved primary field for titles.
  • When the primary field controls columns or swimlanes, its title is displayed as non-editable, while the corresponding move selector remains available for changes.
  • Improved handling when the primary field overlaps with either Board grouping dimension.

• Documentation

  • Clarified Board title-editing and move-control behavior when the primary field is used for grouping or swimlanes.

📝 Walkthrough

Walkthrough

The Board detects when its primary field matches its grouping property. It renders the primary value as plain text and keeps the column selector editable. Documentation and a regression test define this behavior.

High-Level Assessment

The following are alternative approaches to this PR:

1. Disallow primary and grouping collisions

• ➕ Prevents duplicate semantics at configuration time.
• ➕ Keeps card rendering logic unconditional.
• ➖ Unnecessarily restricts two independent view and collection settings.
• ➖ Requires validation and configuration recovery for existing collisions.

2. Remove the column selector on collision

• ➕ Preserves inline primary-field editing.
• ➕ Also leaves only one editor for the shared value.
• ➖ Removes the board-specific move affordance.
• ➖ Makes moving cards inconsistent depending on primary-field configuration.

Recommendation: Keep the PR's conditional title rendering. It preserves valid independent settings and retains the board's purpose-built column movement control while removing only the redundant editor.

1. Swimlane cards still show duplicate editors ✓ Resolved 🐞 Bug ≡ Correctness

Description

titleEditableViaCell disables the title cell only when titleProperty.key matches
groupProperty.key, ignoring swimlaneProperty.key. When a Board groups columns by one field and
swimlanes by the primary field, the card still renders an editable title cell alongside the “Move to
swimlane” select for the same value.

Code

src/lib/components/BoardCollectionView.svelte[R157-159]

+	const titleEditableViaCell = $derived(
+		titleProperty != null && titleProperty.key !== groupProperty?.key
+	);

●●● Strong

Accepted precedent fixes duplicate Board dimensions when groupBy and swimlaneBy collide; this is the
same redundant-control bug.

PR-#218

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The new condition compares the title only with groupProperty, while the same component renders a
separate swimlane <select> bound to swimlaneProperty. Therefore a primary field matching only
swimlaneBy bypasses the new guard and remains editable in both controls.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`titleEditableViaCell` checks only the column grouping property, so a primary field that matches `swimlaneProperty` still produces two editable controls for the same value: the title `PropertyValueCell` and the “Move to swimlane” select.

## Fix Focus Areas
- src/lib/components/BoardCollectionView.svelte[157-159]
- src/lib/components/BoardCollectionView.svelte[526-540]

## Recommended Fix
Make `titleEditableViaCell` false when the title property matches either `groupProperty` or `swimlaneProperty`. Add a regression test with `primaryFieldKey` equal to `swimlaneBy`, a different `groupBy`, and assertions that the card has plain title text and only one editor for that value.
