Systematic configuration overhaul: .codev/ directory, pluggable consultations, eliminate codev update #618

Summary

Major configuration overhaul to make codev more systematically configurable, drawing inspiration from Claude Code's .claude/ directory pattern. This covers several related concerns:

1. Unified .codev/ configuration directory

• Mirror Claude Code's pattern: ~/.codev/ (global) and .codev/ (project-level)
• af-config.json moves into .codev/
• Project-level settings override global defaults
• Clean separation between framework files (protocols, templates) and user config

2. Pluggable consultation models

• Users should be able to configure which models porch uses for reviews
• Options: "claude-only", "parent" (delegate to architect session — see feat: parent-delegated consultation mode for porch #614), custom model lists
• Addresses SPIR-SOLO #592 (SPIR-SOLO — users with only one model available)
• Config example: { "porch": { "consultation": ["claude"] } } or "parent"

3. Eliminate codev update

• When a user installs a new version of codev, they should automatically get the latest protocols
• Framework files (protocols, templates, roles) should be read from the installed package at runtime, not copied into the project
• User customizations in .codev/ override the defaults without needing to copy/modify framework files
• codev update becomes unnecessary

4. Remote protocol sources

• Users should be able to specify a remote repo where protocols are defined
• Enables teams to maintain custom protocols in a shared repo
• Config example: { "protocols": { "source": "github:myorg/my-protocols" } }

• SPIR-SOLO #592 — SPIR-SOLO (single model support)

Context

• Current af-config.json structure: shell commands, templates dir, roles dir, porch checks
• codev update currently copies skeleton files into the project
• codev-skeleton/ contains the framework files that get copied
