Enable standalone nexus operations in devserver, and support delete

[S15]

What changed?

• Enables standalone nexus operations in devserver
• Adds support for temporal nexus operation delete

Checklist

Design

• This feature does not depend on Cloud-only APIs or behavior (it works against an OSS server)
• New commands follow temporal <noun> <verb> structure (e.g. temporal workflow start)
• New flags are named after the API concept, not the implementation mechanism (good: --search-attribute, bad: --index-field)
• New flags don't duplicate an existing flag that serves the same purpose
• New flags do not have short aliases without strong justification
• Experimental features are marked with (Experimental) in commands.yaml

Help text (see style guide at the top of commands.yaml)

• All flags shown in help text and examples are implemented and functional
• Summaries use sentence case and have no trailing period
• Long descriptions end with a period and include at least one example invocation
• Examples use long flags (--namespace, not -n), one flag per line
• Placeholder values use YourXxx form (YourWorkflowId, YourNamespace)

Behavior

• Results go to stdout; errors and warnings go to stderr
• Error messages are lowercase with no trailing punctuation

Tests

• Added functional test(s) (SharedServerSuite)
• Added unit test(s) (func TestXxx) where applicable

I edited the title to that that action is not lost in the next cli release notes, and I changed checkbox from unit test to functional test (SharedServerSuite, I believe, indicates functional test).

It may be useful to include a test to verify that it deletes the latest run if runId is not supplied. I approved, but let me know if you decide to add that. Thanks
