#230 data·delete logger double-quotes the data name in log output

The swamp data delete log-mode output emits the data name with doubled quotes (""result"") instead of single quotes ("result").

Reproduction

$ swamp model create command/shell hello-world
$ swamp model method run hello-world execute --input run='echo hi' --skip-reports
$ echo y | swamp data delete hello-world result --log
About to delete 1 version(s) of "result" from hello-world. Proceed? [y/N] y
19:00:25.924 INF data·delete Deleted 1 version(s) of ""result"" for "hello-world" ("command/shell")

The Deleted N version(s) of ""result"" for "hello-world" line wraps result in two pairs of quotes. All other quoted fields in the same line ("hello-world", "command/shell") are quoted normally — only the data name is doubled.

The --version variant is affected the same way:

19:00:21.623 INF data·delete Deleted version 1 of ""result"" for "hello-world" ("command/shell")

Expected

Single quotes around the data name, matching every other quoted identifier in the line:

INF data·delete Deleted 1 version(s) of "result" for "hello-world" ("command/shell")

Notes

• The interactive prompt (About to delete 1 version(s) of "result" from hello-world.) quotes correctly — only the post-delete confirmation line is wrong.
• JSON output (--json) is unaffected.
• Likely a string-formatter call inside the data·delete logger that wraps an already-quoted value (e.g. JSON.stringify on a string that already has quotes, or a %q-equivalent applied to "${name}").
• Caught while writing the swamp-club manual page for swamp data delete — had to choose between documenting the artifact verbatim or normalising it. Cleaner output upstream lets the docs match the CLI exactly.
