Comprehensive documentation update for HN launch

[waleedkadous]

Summary

Fixes #558. Systematic documentation audit and update across all user-facing docs in preparation for HN launch.

• Replace all deprecated af dash with af workspace (README, tips, AGENTS.md, CLAUDE.md, MANIFESTO, INSTALL)
• Add required --protocol flag to af spawn examples
• Update stale version references from v1.x to v2.x era
• Modernize Remote Access section (manual SSH → af workspace start --remote)
• Add 4 new FAQ sections: protocol overview, porch, Agent Farm optionality, remote access
• Add ASPIR, BUGFIX protocols and porch CLI to cheatsheet
• Add porch as fourth CLI tool in commands/overview.md
• Add tips for remote access, cross-workspace messaging, porch checks config
• Fix stale SP(IDE)R-SOLO and MCP references in why.md

Files Changed

• README.md — CLI commands, version refs, remote access
• docs/faq.md — New protocol and feature FAQ sections
• docs/tips.md — New tips, fixed commands
• docs/why.md — Fixed stale references
• codev/resources/cheatsheet.md — Added protocols, porch CLI
• codev/resources/commands/overview.md — Added porch
• AGENTS.md / CLAUDE.md — Updated af dash → af workspace (kept in sync)
• MANIFESTO.md / INSTALL.md — Updated commands

Test plan

• Verify no af dash references remain in modified files
• Verify AGENTS.md and CLAUDE.md are byte-identical
• Verify all af spawn examples include --protocol flag
• Review each file for internal link consistency

Architect Review — Requested Changes

Core changes are solid (af dash → af workspace, version updates, protocol/porch additions). Three corrections needed:

1. Remove --remote flag references

af workspace start --remote user@host does not exist. Remote access is now handled by cloud connectivity (af tower connect). Remove the --remote examples from:

• README.md Remote Access section
• docs/faq.md "Can I access Agent Farm remotely?"
• docs/tips.md "Remote Access" section

Replace with a brief mention of cloud access via af tower connect and codevos.ai, or simply remove the remote access sections if they can't be made accurate.

2. Remove cross-workspace messaging syntax

af send marketmaker:architect "..." is not a real syntax. Remove the "Cross-Workspace Messaging" section from tips.md entirely.

3. Fix af tower register → af tower connect

In cheatsheet.md, change af tower register to af tower connect.
