Forbids empty multiaddr, fixes #6354

feat: improve errors when a path fails to parse

fix vendoring dependencies when building the source tarball

core: Use correct default for connmgr lowWater

Most people weren't affected by this as those values are set in config at init, but for others it would be rather hard to debug.

TMPDIR is a special variable indicating the _system_ temporary directory root.
Unfortunately, go refuses to honor `go.mod` files in this directory to prevent
random `/tmp/go.mod` files from messing with modules cloned into `/tmp`.

The fix is simple: rename TMPDIR to TEMP.

This helps with issues like #4190 by telling the user the path that failed to
parse.

github: turn issue template into a multiple-choice question

This way:

1. Contributors have to click _something_ so they're more likely to read this.
2. Each issue gets correctly labeled.
3. We can customize the template for different types of issues so contributors
don't have to read as much.
