A dailies picker (zkd-style): lists the last `journal_days` (default 7) days newest-first, previews existing journals and shows "@create" for new ones, and opens the chosen day (creating if new). Journals resolve by their ISO-date title, so no new RPC is needed. picker.select gains an optional Telescope preview pane. e2e covers the recent-days list (exists/@create across a month boundary) and open-on-pick via a stubbed vim.ui.select.

--- A single selection primitive. Uses built-in `vim.ui.select` so headless e2e
|
|
--- needs no plugins; auto-upgrades to Telescope when it is installed and not
|
|
--- explicitly disabled. Tests set `vim.g.heph_force_ui_select` and stub
|
|
--- `vim.ui.select`, so a picker never blocks in `--headless`.
