feat(launcher): wire the local runtime — codex --oss over ollama

ai --runtime local now launches codex against the machine's ollama (explicit --local-provider=ollama, model from AI_LOCAL_MODEL, default gpt-oss:120b). Verified end to end with a codex exec completion through the local model. The dependency check probes AGENT_BIN now that AGENT_CMD carries flags. This makes codex-over-ollama the de-facto answer to the runtime spec's first-supported-local-CLI blocker.

 *** 2026-07-13 Mon @ 13:34:17 -0500 Hook parity inventoried — only two hooks carry real porting work
 Full mapping in [[file:docs/design/2026-07-13-runtime-portability-inventories.org]]. AskUserQuestion deny is moot off Claude (no popup tool to deny); PostToolUse validators survive via the bundles' git pre-commit hooks; clear-resume folds into the session-plumbing child; session-title is cosmetic. Real gaps: PreCompact priority-save (prose downgrade) and Stop wrap-teardown (Codex notify / manual elsewhere) — decisions in the VERIFY below.
 
+*** 2026-07-13 Mon @ 23:04:21 -0500 Local runtime wired — ai --runtime local runs codex --oss over ollama
+The reserved lane went live the same day: =local= maps to =codex --oss --local-provider=ollama -m $AI_LOCAL_MODEL= (default gpt-oss:120b; qwen3-coder:30b via the env var). Verified end to end: =codex exec --oss --local-provider=ollama -m gpt-oss:120b= returned a correct completion through the local model (~7K tokens). The explicit provider flag avoids config.toml dependence (a root-level =oss_provider= key would also work; appending to the file lands in the last TOML table and silently does nothing — learned live). Dependency check keys on AGENT_BIN (codex) now that AGENT_CMD carries flags. This partially answers the spec's "first supported local editing CLI" blocker: codex-over-ollama is the de-facto v1. The model-floor child's live trial (a takuzu session under =ai --runtime local=) is the next step.

 *** 2026-07-13 Mon @ 16:39:41 -0500 Launcher runtime flag built — ai --runtime claude|codex
 Shipped TDD (new =scripts/tests/ai-launcher-runtime.bats=, 6 tests red→green): =--runtime= flag + =AI_RUNTIME= env on =bin/ai=, runtime→CLI mapping (claude default, codex 1:1 — both take the opening line as a positional prompt), runtime-aware dependency check, =local= reserved with a clear not-wired-yet error (pending the model-floor evaluation), and a =--print-launch= mode as the test seam (prints the pane launch command, no tmux/fzf). Kept small per the 2026-06-24 helper-task caveat — dispatch pre-parse only, no launcher restructure. The Emacs-side equivalent (ai-term multi-LLM) remains .emacs.d's June handoff. Live smoke: correct commands for both runtimes against real projects.
