fix(errors): separate informational notes from actionable alternatives in ContextError

[BYK]

Summary

• Adds an optional note parameter to ContextError for diagnostic context, rendered as a separate "Note:" section after the actionable "Or:" alternatives
• Fixes the CLI-VN error where the "Or:" section contained non-actionable DSN resolution info instead of steps the user can take
• Moves DSN diagnostic info from alternatives to note in issue list and project view commands

Before:

Or:
  - Found 2 DSN(s) that could not be resolved
  - You may not have access to these projects, or you can specify the target explicitly

After:

Or:
  - Run from a directory with a Sentry-configured project
  - Set SENTRY_ORG and SENTRY_PROJECT (or SENTRY_DSN) environment variables
  - Run 'sentry org list' to find your organization slug
  - Run 'sentry project list <org>/' to find project slugs

Note: Found 2 DSN(s) that could not be resolved — you may not have access to these projects

Fixes CLI-VN
