test(file-token): add parse, diff, views, edit, and navigation tests

Problem: the file: token implementation had no test coverage.

Solution: add spec/file_spec.lua covering parse.body extraction,
malformed token handling, duplicate token stop-parsing, diff
reconciliation (store/update/clear/round-trip), LineMeta population
in both views, :Pending edit -file, and goto_file notify paths for
no-file and unreadable-file cases. All 292 tests pass.

 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.
-

+
+Completion-based recurrence: ~                      *pending-recur-completion*
+By default, recurrence is schedule-based: the next due date advances from the
+original schedule, skipping to the next future occurrence. Prefix the pattern
+with `!` for completion-based mode, where the next due date advances from the
+completion date: >
+    rec:!weekly
+<
+Schedule-based is like org-mode `++`; completion-based is like `.+`.

+Google Calendar: ~
+Recurrence patterns map directly to iCalendar RRULE strings for future GCal
+sync support. Completion-based recurrence cannot be synced (it is inherently
+local).

-    `!`           Toggle the priority flag on the task at cursor
-    `D`           Prompt for a due date on the task at cursor
-    `<Tab>`       Switch between category view and priority view
-    `U`           Undo the last `:w` save
-    `g?`          Show a help popup with available keys
+    `q`           Close the task buffer (`close`)
+    `<CR>`        Toggle complete / uncomplete (`toggle`)
+    `!`           Toggle the priority flag (`priority`)
+    `D`           Prompt for a due date (`date`)
+    `<Tab>`       Switch between category / queue view (`view`)
+    `U`           Undo the last `:w` save (`undo`)

+    `O`           Insert a new task line above (`open_line_above`)
+    `gf`          Open the file attached to the task under the cursor (`goto_file`)

     `zo`          Unfold the current category section (category view only)

+
+`at` supports count: `d3at` deletes three consecutive tasks. `it` selects
+the description text between the checkbox prefix and trailing metadata
+tokens (`due:`, `cat:`, `rec:`), making `cit` the natural way to retype a
+task description without touching its metadata.

+          next_due = "2026-03-01",  -- earliest future due date, or nil
+        }
+<
+    The counts are read from a module-local cache that is invalidated on every
+    `:w`, toggle, date change, archive, undo, and sync. The first call triggers
+    a lazy `store.load()` if the store has not been loaded yet.
+
+    Done, deleted, and `someday` sentinel-dated tasks are excluded from the
+    `overdue` and `today` counts. The `someday` sentinel is the value of
