Problem: after apply_template writes a file's content to the buffer,
cursor positioning was left entirely to the user's setup_code hook,
forcing everyone to reimplement the same placeholder-stripping logic.
Solution: add an optional templates.cursor_marker config key. When set,
apply_template scans the written lines for the marker, strips it, and
positions the cursor there via bufwinid so it works in both the
provisional and existing-file paths.
Problem: new solution files were always created empty, requiring users
to manually paste boilerplate or rely on editor snippets that fire
outside cp.nvim's control.
Solution: add an optional template field to the language config. When
set to a file path, its contents are written into every newly created
solution buffer before the setup_code hook runs. Existing files are
never overwritten.
Problem: vim.loop is deprecated since Neovim 0.10 in favour of vim.uv.
Five call sites across scraper.lua, setup.lua, utils.lua, and health.lua
still referenced the old alias.
Solution: replace every vim.loop reference with vim.uv directly.
Also fix contest-change detection so URL open logic triggers when either platform or contest changes. This makes :CP next/:CP prev and problem jumps open the correct page when open_url is enabled.

Problem: when opening a contest for the first time (metadata not
cached), the setup_code hook fired before state.set_language() was
called, causing state.get_language() to return nil inside the hook.
Solution: call state.set_language(lang) before the hook in the
provisional-buffer branch of setup_contest(). The value is already
computed at that point and is identical to what setup_problem() sets
later, so the early write is idempotent.
