Include resume entry prose in exported search text

[RowletCC]

The exported resumeSearchText helper drops non-bullet paragraphs beneath an entry subtitle. For example, Processed bathymetry observations. remains in parseResume(...).sections[0].entries[0].markdown but the exported search text contains no bathymetry.

Use the full entry Markdown as the body when flattening each entry, retaining its title and place. This preserves later paragraphs and list content without repeating subtitle/highlight text. The fix is limited to the exported helper; the current repository candidate-directory implementation does not call it, so this does not claim to change the live directory search.

Validation: four independent behavioral checks pass (ordinary paragraphs, non-Latin text across entries, full body without duplicated structured lines, and existing-field preservation). The unchanged baseline fails three and passes one. Both focused search text tests pass. npm run build and tsc -p tsconfig.json --noEmit pass.
