vim.diagnostic.Opts.VirtualText has a `source` option to prefix
diagnostic messages with their source (`'if_many'` or always), but the
newer virtual_lines handler never got the same option, even though the
shared helpers it needs (diagnostic_shared.prefix_source/count_sources)
are already render-target-agnostic and used by virtual_text as-is.
Add the same `source` field to vim.diagnostic.Opts.VirtualLines and
apply it in the virtual_lines handler right after message formatting,
mirroring virtual_text's own ordering (format first, then prefix the
source onto the already-formatted message).

Problem:
Handlers defer `show()` on unloaded buffers with a buffer-local BufRead
autocmd whose id is stored per-namespace:
- `noautocmd bwipeout` deletes the autocmd, so the next show/hide fails.
- Showing another buffer in the same namespace cancels the pending show.
Solution:
Handlers skip unloaded buffers. The existing global BufRead autocmd
shows cached diagnostics when the buffer loads.

Problem: Argument type mismatches are excluded from EmmyLua checks.
Solution: Correct runtime annotations and calls, document local checker
workarounds, and enable the diagnostic.

Enable EmmyLua's assign-type-mismatch diagnostic after correcting the
runtime annotations and assignments it flags.
Correct option, tuple, and return types, and use separate locals when a
value changes representation. Add guards and narrow casts where needed
so the runtime passes the stricter check. Regenerate the affected docs.

Enable EmmyLua's need-check-nil diagnostic and resolve nullable values
through more precise types, explicit invariants, and guards for missing
runtime state. Keep analyzer-specific workarounds local and update the
affected API documentation.
Exclude the bundled re.lua from analysis so its nil-check warnings do
not fail CI.

Problem:
`vim.diagnostic.handlers.underline.show` throws `E565: Index out of bounds` when
it tries to underline a diagnostic whose `lnum` is past the end of the buffer.
This happens with stale diagnostics set on an unloaded buffer (e.g. via
`bufadd()`) that are drawn only after the buffer is loaded: by then the file on
disk can be shorter than the `lnum` the diagnostic carried. File pickers
(snacks.nvim) that open files via `bufadd` + `:buffer` hit this whenever an LSP
server has already emitted diagnostics for that URI.
Solution:
Skip diagnostics with an out-of-range `lnum` in the underline handler.
Other handlers `M.virtual_text.show()`, `M.signs.show()`, have a similar condition.

Problem: vim.diagnostic.Opts.VirtualLines.current_line and
vim.diagnostic.Opts.VirtualText.current_line cause redraw
on every CursorMoved event that makes the text jump
uncomfortably with rapid cursor movement.
Solution: `current_line` state is applied only on CursorHold,
while still being cleared on CursorMoved making it so that
until the cursor has stopped on a line, its diagnostic
looks like cursor is not on the line preventing flicker.

Problem: Diagnostic virtual lines are hardcoded with "scroll" for
virt_lines_overflow option.
Solution: Add a `overflow` option to `virtual_lines` config
to support "wrap", "scroll", "trunc", and "auto".

Problem:
Diagnostic highlight groups were applied by iterating and calling
`vim.hl.range` for each group individually. That resulted in multiple
extmarks with the same priority being created separately, which does not
allow `DiagnosticUnnecessary` and `DiagnosticDeprecated` with matching
options override `Diagnostic*` styling.
Solution:
Pass the list of hl-groups to `vim.hl.range` so they are applied
together in the correct order.

Problem:
`nvim_create_autocmd` is too verbose and its `callback` requires extra
"nesting".
Solution:
Introduce `nvim_on`. Start using it internally. Then we can get a feel
for how it should look before making it public.

Extract the diagnostic implementation from
runtime/lua/vim/diagnostic.lua into focused internal modules covering
config, display, float rendering, jump/list helpers, namespace and
storage management, severity/shared utilities, and statusline support.
Move the builtin handlers into runtime/lua/vim/diagnostic/handlers/ and
keep runtime/lua/vim/diagnostic.lua as the public facade that lazily
dispatches to the split modules. This preserves the external
vim.diagnostic API while making the implementation easier to navigate
and reason about.
