fix(cli): remove group navigation from Alexandria list

[developersdigest]

Summary

Alexandria list navigation now walks categories, providers, and individual tools. Remove --groups, --group, and the implicit group lookup after a missing capability. For example, firecrawl alexandria list benzinga lists tools, and firecrawl alexandria list benzinga calendar/ratings opens that tool's contract.

Update help, README, and the bundled beta skill. Preserve exact raw Find Tools request replay for pagination and scoped selectors. Bump the Alexandria beta to 1.23.4-alexandria-beta.10.

Validation

• Build passed.
• All 27 existing Alexandria CLI integration tests passed, including updated checks for removed flags and no group fallback.
• Live discovery returned seven Benzinga tools and expanded the calendar/ratings contract successfully; all discovery receipts were zero credits.

Summary by cubic

Removes group navigation from the Alexandria list command so browsing goes straight from providers to individual tools. The --groups and --group flags and the implicit group fallback after a missing capability are gone; a missing capability now shows no matching tools instead of a group listing.

Breaking changes

• --groups and --group now error as unknown options; use the full capability ID, e.g. list benzinga calendar/ratings.
• Help text, README, and the bundled beta skill drop group examples, and the beta bumps to 1.23.4-alexandria-beta.10.

Shadow auto-approve: would require human review. Removes the Alexandria CLI's --groups/--group flags and implicit group fallback, changing list navigation to go straight from providers to tools. This is a deliberate breaking change to the public CLI contract that a human should approve.
