v0.3.0

Changed

• search_issues responses are now field-driven: each issue contains key, url, and only the requested fields (previously a fixed set of keys)
• ADF-to-text conversion joins adjacent inline nodes without inserting spaces (formatting marks no longer split words) and separates block nodes with blank lines instead of single spaces
• key is no longer selectable in search_issues fields — it is always returned, and requesting it now returns VALIDATION_ERROR
• The package installs as src rather than exposing jira, tools, and utils as top-level modules, so python -m src works outside the project directory

Fixed

• JQL bound checks match bounding keywords as whole words and ignore matches inside quoted strings and the ORDER BY clause
• Attachment filename sanitization strips Windows-style path separators and rejects dot-only names (., ..), falling back to attachment
• Attachment downloads report file-write failures as DOWNLOAD_FAILED instead of raising
• search_issues derives is_last from next_page_token when Jira omits isLast, so clients no longer stop paginating while a page remains
