Show the program's name in help output

[jonhadfield]

app.HelpName was set to "-", so help called the command - everywhere:

NAME:
   - - Standard Notes CLI

USAGE:
   - [global options] command [command options]

Subcommands inherited it, so sn add --help read - add - add items. The README tells a new user to run sn --help as their first step, which made this the first thing they saw.

Deleting the line lets urfave/cli default HelpName to app.Name, which is already "sn":

NAME:
   sn - Standard Notes CLI

USAGE:
   sn [global options] command [command options]

and sn add --help now reads sn add - add items.

Nothing referenced HelpName anywhere else. go build, go vet and go test ./... pass; verified by building both versions and comparing their output.

What changed in this PR

Removes an explicit app.HelpName = "-" override so urfave/cli help output uses the application name (app.Name, already set to "sn") rather than displaying - for the program and subcommands.

Changes:

• Deleted the app.HelpName = "-" assignment to allow the default help naming behavior.
• As a result, sn --help and subcommand help (sn add --help, etc.) display the correct program name.

File	Description
cmd/​sncli/​main.go	Removes the HelpName override so help output reflects app.Name (sn).
