docs: Conductor strips canonical API keys (not just "doesn't inherit")

The prior docs framed the GSTACK_* prefix as collision-avoidance:
"Conductor exposes API keys under a GSTACK_ prefix so it never
collides with whatever the host system has set." That understates
the mechanism — Conductor actively strips ANTHROPIC_API_KEY and
OPENAI_API_KEY from every workspace's process env, so setting them
in ~/.zshrc or .env doesn't help. The fix path is to set the
GSTACK_-prefixed forms in Conductor's workspace env config; Conductor
passes those through untouched.

Three docs updated to reflect the strip, not the polite framing:
USING_GBRAIN_WITH_GSTACK.md (Conductor section), CONTRIBUTING.md
(Conductor workspaces paragraph), CHANGELOG.md (release summary).

README.md gains a "Running gstack in Conductor?" callout in the
GBrain section pointing at the canonical doc's anchor, plus a fourth
path entry (remote gbrain MCP / split-engine) that was already
documented in USING_GBRAIN but missing from the README summary.

## **Conductor workspaces wire `GSTACK_*` keys straight into gbrain embeddings and paid evals.**
## **No more sourcing keys from your shell before every paid run.**
Conductor exposes API keys under a `GSTACK_` prefix so it never collides with whatever the host system has set. The trade-off is that gbrain's embedding pipeline and `@anthropic-ai/claude-agent-sdk` read the canonical `OPENAI_API_KEY` / `ANTHROPIC_API_KEY` names. The new `lib/conductor-env-shim.ts` bridges the gap: it promotes the prefixed form to canonical when canonical is empty. Four TS entry points import the shim as a side effect (`gstack-gbrain-sync.ts`, `gstack-model-benchmark`, `preflight-agent-sdk.ts`, `e2e-helpers.ts`). `USING_GBRAIN_WITH_GSTACK.md` and `CONTRIBUTING.md` document the pattern, plus the checklist for adding the import to new entry points.
Conductor explicitly strips `ANTHROPIC_API_KEY` and `OPENAI_API_KEY` from every workspace's process env, so `.env` copies and `~/.zshrc` exports never reach gbrain's embedding pipeline or `@anthropic-ai/claude-agent-sdk`. The fix path is `GSTACK_ANTHROPIC_API_KEY` / `GSTACK_OPENAI_API_KEY` — Conductor passes those through untouched. The new `lib/conductor-env-shim.ts` closes the loop on the gstack side: it promotes the prefixed form to canonical when canonical is empty. Four TS entry points import the shim as a side effect (`gstack-gbrain-sync.ts`, `gstack-model-benchmark`, `preflight-agent-sdk.ts`, `e2e-helpers.ts`). `README.md`, `USING_GBRAIN_WITH_GSTACK.md`, and `CONTRIBUTING.md` document the pattern, plus the checklist for adding the import to new entry points.
