Reconciles the "pluginify everything" refactor (moving provider adapters, platform adapters, and terminal backends out of core into plugins/) with 267 commits of main. main had 515 edits across 635 files; our branch moved 98 files into plugins/. The dangerous class was main editing files at OLD paths that we relocated — handled below. STRUCTURAL DECISIONS ai-gateway + vercel_sandbox: honored main's PR #33067 deletion. Dropped our orphaned plugins/terminals/vercel/ dir and all 3 stale vercel refs that survived in pyproject (workspace member, [all] entry, uv source). tools/lazy_deps.py: kept mai...

Move provider adapters (anthropic, bedrock, azure), platform adapters (telegram, slack, discord, feishu, dingtalk, matrix), and terminal backends (modal, daytona) out of core into plugins/ workspace members. Core references them via the plugin registries (get_provider_namespace / get_provider_service / get_tool_provider / get_credential_pool_hook) instead of direct imports. Provider/platform/terminal adapters relocated under plugins/; pyproject extras reference workspace members; nix variants aggregate per-platform extras. Anthropic credential discovery + OAuth-masquerade guard live in the plu...
