Working with love2d.nvim

When modifying this plugin:

1. Read the existing code first — match the project's conventions
2. Check AGENTS.md for project-specific rules and file structure
3. Look at existing tests/*_spec.lua files to match testing style
4. Look at existing autocmd patterns in lua/love2d/autocmd.lua

Architecture Notes

• Module dispatch — init.lua is a thin dispatcher. setup() calls config, lsp, autocmd, and events modules. No logic lives in init.
• Job management — love2d.job module manages process lifecycle (run, watch, stop). Single concurrent instance via job.state.id.
• Output panel — love2d.output module manages a floating window for LÖVE stdout/stderr with inline diagnostics via vim.diagnostic.
• Event-driven — love2d.events detects project enter/leave and fires User EnterLove2DProject/LeaveLove2DProject. Other modules subscribe.
• LSP integration — love2d.lsp dynamically injects/removes LÖVE library paths on project enter/leave. Uses vim.lsp.config config-chain merge.
• Project detection — love2d.utils walks up from CWD to find a LÖVE root (conf.lua with love.conf, main.lua with LÖVE callbacks/modules).
• Vendored libraries — Do NOT edit libraries/love2d/ or libraries/luasocket/. These are git submodules with LÖVE/LuaSocket type definitions.
