* fix(#1521): resolve own runtime + worktrees-off for all non-Claude installs
Generalizes the Codex-only #1515/#1519 fix to every non-Claude runtime, and
wires it into the real install path (where it was previously dead-on-arrival).
Root causes:
1. The runtime-default stamping lived only in `_applyRuntimeRewrites`, but the
installer emits `gsd-core/workflows/*.md` via `copyWithPathReplacement`, which
never calls it — so a real `--codex`/`--cursor`/etc. install emitted
`--default claude` and worktrees-on. RUNTIME mis-resolved to claude and the
workflow ran executors unisolated against the main checkout. (#1515/#1519 were
also dead-on-arrival in real installs; this repairs them.)
2. Only `case 'codex'` was stamped; every other non-Claude runtime kept the
Claude default.
Fix:
- New `_stampNonClaudeRuntimeDefaults(content, runtime)` (single shared helper)
stamps `--default <runtime>` + `use_worktrees=false` for every `runtime !=
claude`; called from both `_applyRuntimeRewrites` and, crucially,
`copyWithPathReplacement` in bin/install.js (the real workflow emit path).
- Generalize the fail-closed worktree guard `= codex` -> `!= claude` in
execute-phase/quick/diagnose-issues (worktree isolation is Claude-Code-only).
- Flip manager/autonomous inline-vs-background gating to `codex -> background,
everything-else -> inline` (research: only Codex can background-nest the
pipeline's subagents; all others run inline, which they support).
Worktree-capability determination is research-backed (official docs for all 14
non-Claude runtimes: none honor GSD's isolation="worktree" mechanism, only Codex
background-nests). New end-to-end real-install test asserts the EMITTED workflow
is stamped — the regression guard that would have caught the dead-on-arrival bug.

* fix(#1515): make Codex installs resolve their own runtime and fail closed on worktrees
A Codex install with a runtime-neutral .planning/config.json resolved
RUNTIME=claude and enabled git worktree isolation, which Codex's
spawn_agent cannot honor. Two root causes:
1. Workflows read `config-get runtime` / `config-get workflow.use_worktrees`
without `--raw`, so config-get's JSON-quoted output ("codex") was captured
verbatim into the bash var and broke every `[ "$RUNTIME" = ... ]` check —
the Codex fail-closed guard was dead even when runtime:codex was explicit,
and Claude's own worktree degrade-check was dead too. Add `--raw` to those
reads across execute-phase, autonomous, manager, diagnose-issues, quick.
2. The conversion engine emitted `--default claude` for every runtime. Stamp
the codex-emitted workflows to `--default codex` (runtime) and
`--default false` (use_worktrees) in _applyRuntimeRewrites case 'codex', so
a neutral config on a Codex install resolves runtime=codex / worktrees off.
Also extend the Codex fail-closed worktree guard to quick.md and
diagnose-issues.md (they spawned isolation="worktree" with no runtime guard).
Regression test asserts source<->engine parity across all five workflows
(DEFECT.GENERATIVE-FIX) plus fast-check property coverage of the stamping.
Closes#1515
