Changelog

Add bidirectional GitHub Projects v2 sync for project assignment:

when a task is assigned to a PrivStack project linked to a GitHub

Project, it now appears on the GitHub board. Unassigning removes it.

Two scenarios on assign:

• If the task is already a GitHub issue, add it to the project via

the addProjectV2ItemById GraphQL mutation.

• If the task is local-only, create a GitHub issue first (in a repo

matching the project's org/user from configured issue sources),

then add the new issue to the project.

On unassign: remove the item from the GitHub Project via the

deleteProjectV2Item mutation. The issue itself is not deleted.

Changes:

• GitHubIssue model: add NodeId from REST API node_id field
• GitHubIssueFieldMapper: persist github_node_id in custom fields

during issue sync for later use in project mutations

• TaskItem: add GitHubNodeId convenience accessor
• GitHubProjectApiClient: add AddItemToProjectAsync and

RemoveItemFromProjectAsync GraphQL mutations

• GitHubProjectSyncService: add PushTaskToProjectAsync and

RemoveTaskFromProjectAsync with issue creation fallback and

node_id resolution; inject IGitHubIssueApiClient and

GitHubIssueSourceService for repo resolution

• TasksViewModel.Projects: hook FireGitHubProjectSync into

AssignTaskToProject, BulkAssignToProject, and

ApplyProjectEditorResultAsync (fire-and-forget with error toast)

• TasksPlugin: share GitHubIssueApiClient instance between issue

sync and project sync services

API-created tasks (via IApiProvider) were missing updated_at in the

create payload because the caller (fix-bugs skill, external API)

doesn't include timestamps. The Rust backend auto-sets created_at

but not updated_at, leaving it as DateTimeOffset.MinValue.

• HandleCreateTaskAsync: inject created_at and updated_at if missing
• HandleUpdateTaskAsync: always set updated_at to now on PATCH
• UtcToLocalConverter: return null for MinValue dates so the detail

panel shows blank instead of "Jan 1, 0001 12:00 AM"

Remove InvalidateVisual() from the catch block — Avalonia throws

if a visual is invalidated during an active render pass. The

compositor will naturally re-render on the next frame without it.

All toolbar controls now use consistent Compact sizing:

• Font: ThemeFontSizeXsSm (12px) everywhere (was ThemeFontSizeSm/13px

on project row, mixed elsewhere)

• Padding: 8,6 on all ComboBoxes, buttons, toggles (was 12,6 / 10,6 /

missing on filter ComboBoxes)

• CornerRadius: ThemeRadiusSm (6px) on all controls (was ThemeRadiusXs)
• VerticalAlignment=Center on all elements for proper row alignment

Also changed right-side filter WrapPanel to a horizontal StackPanel

with consistent Spacing="8" to eliminate the per-item margin hacks

(Margin="0,0,12,4") that caused uneven spacing.

GitHub Sync: The project picker state was missing an error message

display, so GraphQL errors were silently swallowed. Added error

TextBlock and improved the auto-fetch catch to surface the error.

The SyncDirection ComboBox used ComboBoxItem wrappers with

SelectedItem bound to a string — replaced with x:String items.

Also normalize corrupted SyncDirection values on load.

Settings Overlay: Same ComboBoxItem binding bug on StatusCategory,

FieldType, and RuleTriggerType dropdowns. Replaced with ItemsSource

+ SelectedValueBinding + DisplayMemberBinding pattern using static

KeyValuePair arrays in the ViewModel.
