Make .claw the only user-facing config namespace

Agents, skills, and init output were still surfacing .codex/.claude paths even though the runtime already treats .claw as the canonical config home. This updates help text, reports, skill install defaults, and repo bootstrap output to present a single .claw namespace while keeping legacy discovery fallbacks in place for existing setups.

Constraint: Existing .codex/.claude agent and skill directories still need to load for compatibility
Rejected: Remove legacy discovery entirely | would break existing user setups instead of just cleaning up surfaced output
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep future user-facing config, agent, and skill path copy aligned to .claw and  even when legacy fallbacks remain supported internally
Tested: cargo fmt --all --check; cargo test --workspace --exclude compat-harness
Not-tested: cargo clippy --workspace --all-targets -- -D warnings | fails in pre-existing unrelated runtime files (for example mcp_lifecycle_hardened.rs, mcp_tool_bridge.rs, lsp_client.rs, permission_enforcer.rs, recovery_recipes.rs, stale_branch.rs, task_registry.rs, team_cron_registry.rs, worker_boot.rs)
