## Problem
Calling \`:LiveServerStart\` from an oil.nvim buffer (or any URI-scheme
buffer) caused two issues: first, \`find_cached_dir\` entered an
infinite loop as \`fnamemodify(cur, ':h')\` degenerated to \`.\`,
freezing Neovim and pegging the CPU; second, even after fixing the loop,
the server would error out instead of doing the right thing — serving
the directory being browsed.
## Solution
Add a progress check to \`find_cached_dir\` so it bails if the path
stops changing. Fix \`resolve_dir\` to detect URI-scheme buffer names
(e.g. \`oil:///path/to/dir\`) and extract the real filesystem path from
them, so \`:LiveServerStart\` correctly serves the browsed directory.
Also corrects the bug report repro template (\`require('lazy')\`, \`lazy
= false\`, no deprecated \`opts\`) and ignores \`repro.lua\`.
Closes#34
