📝 Full Task Prompt

## Objective
Ensure Jira issue searches carry the full issue body through the typed backend search result, not only a truncated preview, so imported Jira tickets can feed planner prompts.

## Scope
- `src/contracts/project-management-types.ts`
- `src/services/jira-api-client.ts`
- `src/services/sprint-issue-service.ts`
- `tests/backend/services/jira-api-client.test.ts`
- `tests/backend/services/sprint-issue-service.test.ts`
- Symbols: `JiraIssueSearchResult`, `searchIssues`, `normalizeJiraIssueSummary`, `RepositoryIssueSearchResult`

## Implementation Requirements
1. Extend the Jira search result contract to carry full description markdown separately from `bodyPreview`.
2. In `src/services/jira-api-client.ts`, extract the Jira description once and return both the full description markdown and the existing truncated preview.
3. In `normalizeJiraIssueSummary`, populate `issueBodyMarkdown`, `issueCreatedAt`, and `issueUpdatedAt` from Jira search results while preserving existing display fields.
4. Add regression coverage proving Jira generic issue search returns full `issueBodyMarkdown` even when `bodyPreview` is truncated or only used for cards.

## Constraints
- Preserve existing Jira search filters, sort behavior, status handling, and result limit clamping.
- Do not remove or repurpose `bodyPreview`; dashboard issue cards still need concise previews.
- Keep GitHub, GitLab, and non-Jira importer behavior unchanged except for shared type compatibility.

## Verification
- `pnpm exec vitest run tests/backend/services/jira-api-client.test.ts tests/backend/services/sprint-issue-service.test.ts`
- Success means Jira search results include full `issueBodyMarkdown`, preview behavior remains unchanged, and existing Jira search tests still pass.
