* feat(buffer): open as bottom-drawer split like fugitive

Problem: :Pending replaced the current buffer, making it impossible to
view tasks alongside the file being edited. No way to close the drawer
without :q or switching buffers manually.

Solution: open the task buffer in a botright horizontal split instead of
replacing the current buffer. Track the drawer window ID so re-opening
focuses it rather than creating a second split. Set winfixheight so the
drawer keeps its height when other windows open or close. Add q/<Esc>
mappings to close the drawer, and a WinClosed autocmd to clear the
tracked window ID when the user closes it manually. Add drawer_height
config option (default 15).

* fix(buffer): default to natural split height like fugitive

Problem: hardcoded drawer_height=15 was too small and diverged from
fugitive's model. Fugitive issues a plain botright split and lets Vim's
own split rules (equalalways, winheight) divide the available space.

Solution: remove the default height so the split sizes naturally. Only
call nvim_win_set_height when the user sets drawer_height to a positive
value, preserving the opt-in customization path.

 Edit tasks like text. `:w` saves them.
 
-A buffer-centric task manager for Neovim. Tasks live in a plain buffer — add
-with `o`, delete with `dd`, reorder with `dd`/`p`, rename by editing. Write the
-buffer and the diff is computed against a JSON store. No UI chrome, no floating
-windows, no abstractions between you and your tasks.
+<!-- insert preview -->
 
-## How it works
+## Requirements
 
-```
-School
-  ! Read chapter 5                             Feb 28
-  Submit homework                              Feb 25
+- Neovim 0.10+
+- (Optionally) `curl` and `openssl` for Google Calendar and Google Task sync
 
-Errands
-  Buy groceries                                Mar 01
-  Clean apartment
-```
+## Installation
 
-Category headers sit at column 0. Tasks are indented below them. `!` marks
-priority. Due dates appear as right-aligned virtual text. Done tasks get
-strikethrough. Everything you see is editable buffer text — the IDs are
-concealed, and metadata is parsed from inline syntax on save.
-
-## Install
+Install with your package manager of choice or via
+[luarocks](https://luarocks.org/modules/barrettruth/pending.nvim):
 
 ```
 luarocks install pending.nvim
 ```
 
-**lazy.nvim:**
-
-```lua
-{ 'barrettruth/pending.nvim' }
-```
-
-Requires Neovim 0.10+. No external dependencies for local use. Google Calendar
-sync requires `curl` and `openssl`.
-
-## Usage
-
-`:Pending` opens the task buffer. From there, it's just vim:
-
-| Key       | Action                          |
-| --------- | ------------------------------- |
-| `o` / `O` | Add a new task                  |
-| `dd`      | Delete a task (on `:w`)         |
-| `p`       | Paste (duplicates get new IDs)  |
-| `:w`      | Save all changes                |
-| `<CR>`    | Toggle complete (immediate)     |
-| `<Tab>`   | Switch category / priority view |
-| `g?`      | Show keybind help               |
-
-### Inline metadata
-
-Type metadata tokens at the end of a task line before saving:
-
-```
-Buy milk due:2026-03-15 cat:Errands
-```
-
-On `:w`, the date and category are extracted. The description becomes `Buy milk`,
-the due date renders as virtual text, and the task moves under the `Errands`
-header.
-
-### Quick add
-
-```vim
-:Pending add Buy groceries due:2026-03-15
-:Pending add School: Submit homework
-```
-
-### Archive
-
-```vim
-:Pending archive      " purge done tasks older than 30 days
-:Pending archive 7    " purge done tasks older than 7 days
-```
-
-## Configuration
-
-No `setup()` call required. Set `vim.g.pending` before the plugin loads:
-
-```lua
-vim.g.pending = {
-  data_path = vim.fn.stdpath('data') .. '/pending/tasks.json',
-  default_view = 'category',  -- 'category' or 'priority'
-  default_category = 'Inbox',
-  date_format = '%b %d',      -- strftime format for virtual text
-  date_syntax = 'due',        -- inline token name (e.g. 'by' for by:2026-03-15)
-}
-```
-
-All fields are optional. Absent keys use the defaults shown above.
-
-## Google Calendar sync
-
-One-way push of tasks with due dates to a dedicated Google Calendar as all-day
-events.
-
-```lua
-vim.g.pending = {
-  gcal = {
-    calendar = 'Tasks',
-    credentials_path = '/path/to/client_secret.json',
-  },
-}
-```
-
-```vim
-:Pending sync
-```
-
-On first run, a browser window opens for OAuth consent. The refresh token is
-stored at `stdpath('data')/pending/gcal_tokens.json`. Completed or deleted tasks
-have their calendar events removed. Due date changes update events in place.
-
-## Mappings
-
-The plugin defines `<Plug>` mappings for custom keybinds:
-
-```lua
-vim.keymap.set('n', '<leader>t', '<Plug>(pending-open)')
-vim.keymap.set('n', '<leader>T', '<Plug>(pending-toggle)')
-```
-
-| Plug mapping               | Action               |
-| -------------------------- | -------------------- |
-| `<Plug>(pending-open)`     | Open task buffer     |
-| `<Plug>(pending-toggle)`   | Toggle complete      |
-| `<Plug>(pending-view)`     | Switch view          |
-| `<Plug>(pending-priority)` | Toggle priority flag |
-| `<Plug>(pending-date)`     | Prompt for due date  |
-
-## Data format
-
-Tasks are stored as JSON at `stdpath('data')/pending/tasks.json`. The schema is
-versioned and forward-compatible — unknown fields are preserved on round-trip.
-
