agents: simplify prompts now that # is gone from keys

Remove all the quoting instructions, warnings about shell comments,
and "CRITICAL" blocks about single quotes. Keys are plain dashes now.
Agent tool examples are clean and minimal.

-**CRITICAL: Keys containing `#` MUST be wrapped in single quotes in ALL
-bash commands.** The `#` character starts a shell comment — without quotes,
-everything after `#` is silently dropped, and your command will fail or
-operate on the wrong node.
-
-**Single quotes WORK. Do not give up on them.** If you get an error with
-a `#` key, check your quoting — don't assume the tool can't handle it.
-Example that works: `poc-memory graph link-add 'journal#2026-03-01-foo' 'identity#core'`
