feat(hosts): instruction-only tier — a 2KB committed rules digest any agent host can read

New agents-digest/gstack-AGENTS.md (1,765 bytes, hard 2,048-byte budget):
gstack's ethos one-liners, the reuse ladder, and voice rules for hosts with
no install arm — Zed, Amp, Jules, or any AGENTS.md-reading agent. Generated
by scripts/gen-agents-digest.ts, auto-refreshed by gen:skill-docs, committed
like llms.txt so setup's explainer arms can point at it before any toolchain
exists. First line carries the gstack version as its own staleness nudge.

Delivery is print-path + user-performed copy ONLY: setup never writes or
overwrites a user's AGENTS.md (a test pins this — no cp/ln/mv/redirect into
AGENTS.md anywhere in setup). openclaw and hermes explainer arms print the
path; slate keeps routing to the full Claude install and gbrain ships from
its own repo. HostConfig gains the optional install.instructionTier slot,
declared by both instruction-tier hosts. README host table now matches what
setup actually does.

Inspired by dietrichgebert/ponytail's instruction-tier AGENTS.md fallback —
one generated source, never per-host hand copies.

**Instruction-only tier (any rules-reading agent — Zed, Amp, Jules, side projects):**
copy the 2KB digest at [`agents-digest/gstack-AGENTS.md`](agents-digest/gstack-AGENTS.md)
into a location your agent reads (for example, append it to your project's `AGENTS.md`).
It carries gstack's ethos, reuse ladder, and voice rules — no install required. The
digest's first line shows its gstack version; re-copy it after upgrading.
For Codex, setup reads the top-level `model` from
`${CODEX_HOME:-~/.codex}/config.toml` and generates the matching behavioral
