fix: review pass 2 fixes (floor reader bounds, cso start is resumed not retried)

The floor reader reads only the first 64 KiB, takes the first occurrence of the field (the top-level one) and names a non-version string truthfully; /cso resumes a start whose ID never printed instead of retrying it (a run may already exist). Found by /ship pass 2 (Claude adversarial, Codex adversarial + structured).

 - **WARN rows print their action as given** (`_dc_row`): `owner action: ...` for the Capy skill copy, `fix: ...` for the floor, a skipped upgrade and a Node pin, so a lane knows which WARNs it can clear itself.
 - **A Drive copy below the wrapper minimum is a WARN in a direct run too** (`bin/gstack-doctor-check.sh`): with no bootstrapper provenance (`bin/gstack-upgrade`'s installer run, a direct `gstack-doctor --check`), every Drive copy at a bootstrapper revision below `GSTACK_CAPY_MIN_WRAPPER` is `WARN wrapper — every Capy skill copy is below the minimum wrapper 3 (it still works): ...` with the owner action and an ok trailer; only a pre-bootstrapper copy (no `GSTACK_CAPY_WRAPPER=` line) still fails. Found by /ship's red team: raising the minimum to 3 would otherwise have failed every direct run on a machine whose Drive copy is the deployed wrapper 2 until the owner recopied the skill.
 - **A `--for none` session never self-upgrades** (`bin/gstack-capy-session`): an older bootstrapper (wrapper 1 or 2) hands `--for none` to the session in install mode; the session now treats it like `--check` (reports `behind=`, moves nothing) before the installer prints `ok not-needed`; the old bootstrapper's own clone or fast-forward of a below-minimum checkout, before the handover, is unchanged. Wrapper 3 answers `--for none` before the session. The session's header comment describes the `WARN behind` outcome (it said `fail behind`).
-- **/cso** (`cso/SKILL.md.tmpl`): the always-loaded startup block gains two rules. Environment hygiene: prerequisite checks read a variable as set or unset only, and `env`, `printenv`, `set -x`, a bare `set` or `export`, `export $(...)` and `echo "$NAME"` never appear in a tool fence. Tooling errors fail loudly: a non-zero exit with no helper status is retried at most twice (5 s, 30 s) and then ends **not assessed** for whatever the helper never recorded, quoting the command, exit code and stderr tail; never a quiet partial, never another review offered as the missing coverage.

 - **Capy skill and docs** (`capy/skill/gstack/SKILL.md`, `docs/capy-install.md`): the session-start steps cover `--for none`, `floor=`, `behind=` as informational, the Node WARN and the in-place review-voice upgrade; run directories and scratch on Capy live under `~/.capy/work/<name>`, never `/tmp`, which Capy wipes when a machine sleeps.
 - **Result codes** (`lib/result-codes-capy.ts`): `PROJECT_FLOOR_UNMET`, `PROJECT_NODE_PIN_UNMET` and `UPGRADE_SKIPPED`, each with a `docs/troubleshooting.md` anchor.
 - **The trailer's `fix:` after a skipped upgrade is one runnable command** (`bin/gstack-capy-install`): the session's rerun or `bin/gstack-upgrade` (which prints its own refusal), never the refusal's prose; that prose, with its `GSTACK_UPGRADE_FORCE=1` escape hatch for a live lease, stays on the `WARN behind` row (found by /ship's adversarial review: an agent told to run the `fix:` command was being handed prose with the note separator in it).
-- **The floor reader is whitespace-insensitive** (`bin/gstack-doctor-check.sh`): `min_gstack_version` on one line and its value on the next, which `lib/ship-policy.ts` accepts, is read; a present value that is not a dotted version SKIPs as such instead of as "null or absent" (found by Codex in /ship's adversarial review).
+- **The floor reader is whitespace-insensitive** (`bin/gstack-doctor-check.sh`): `min_gstack_version` on one line and its value on the next, which `lib/ship-policy.ts` accepts, is read, the first occurrence (the top-level field) wins, only the first 64 KiB of the file are read, and a present string value that is not a plain dotted version SKIPs as such instead of as "null or absent" (found by Codex and the adversarial pass in /ship's review).
 
 ### Tests
 - `test/gstack-doctor.test.ts`: the `floor` row's four outcomes (absent file, null key, met, unmet with the wrapper fix and without it) and the Node-only WARN beside a Bun-plus-Node FAIL; every required-row list gains `floor`.
