docs: update help file for new command surface and document reload

Problem: the help file listed compile as the default subcommand, still
included the stop subcommand, omitted the reload provider field, and
had a misleading claim about shipping with zero defaults.

Solution: make toggle the default in the commands section, remove stop
from subcommands, add reload to provider fields, fix the introduction
text, reorder API entries to match new primacy, and add an output path
override example addressing #26/#27.

@ -10,8 +10,8 @@ preview.nvim is an extensible framework for compiling documents asynchronously
in Neovim. It provides a unified interface for any compilation workflow —
LaTeX, Typst, Markdown, or anything else with a CLI compiler.
The plugin ships with zero provider defaults. Users must explicitly configure
their compiler commands. preview.nvim is purely an orchestration framework.
The plugin ships with opt-in presets for common tools (Typst, LaTeX, Pandoc)
and supports fully custom providers. See |preview.nvim-presets|.

Compile the document in the given buffer (default: current).

Kill the active compilation process for the buffer.
preview.clean({bufnr?}) *preview.clean()*
Run the provider's clean command for the buffer.
preview.toggle({bufnr?}) *preview.toggle()*
Toggle auto-compile for the buffer. When enabled, the buffer is
immediately compiled and automatically recompiled on each save
(`BufWritePost`). Call again to stop.
preview.compile({bufnr?}) *preview.compile()*
One-shot compile the document in the given buffer (default: current).
preview.stop({bufnr?}) *preview.stop()*
Kill the active compilation process for the buffer. Programmatic
