chore(release): 0.3.1 (#51)

Two data-loss fixes since 0.3.0, both on the Markdown write path: `lash add`
reassigning the previous task's body to the new task, and `lash format`
deleting everything inside `## Tasks` it could not rebuild from the model.

 ## [Unreleased]
 
+## [0.3.1] - 2026-08-11
+
+Two fixes to the root cause the 0.3.0 sweep left standing. The parsed model
+does not record a task's free-text body, and both write paths assumed a task
+was its checkbox line plus its annotation block. Both lost content and exited 0.
+
+### Fixed
+
+- `lash add` no longer inserts a new task between the previous task's title and
+  its body, which reassigned that body to a task it had nothing to do with.
+  Tasks carry prose, numbered steps and acceptance criteria that the parser does
+  not record, so the insertion point landed one line below the title. Nothing
+  surfaced it: `lash lint` passes on the damaged file, and `lash show` prints a
+  task's ID, title, status, file and labels but never its body. Present since
+  0.1.0.
+- `lash format` no longer deletes what it cannot rebuild from the parsed model.
+  0.3.0 stopped it from dropping whole sections, but the `## Tasks` span was
+  still regenerated wholesale from the task tree, so free-text bodies, `---`
+  separators, comments, `### Subsection` headings and the wrapped continuation
+  lines of every contextual note were lost on each run. Formatting
+  `lash.index.md` produced a 238-line diff, nearly all of it deletion; it is 52
+  lines now. The formatter regenerates the lines the model accounts for and
+  copies every other line through.
+
+### Changed
+
+- Blank lines between tasks survive `lash format`. They belong to the author,
+  and `lash add` writes one when it appends below a task that has a body.
+
