feat(kernel): MINT-ZUSE, a word of the lone node (request 2) (#92, 4.6) [skip ci]

Browse Source 
word_count 317 -> 318; no POST case (it waits for a stick and YES, as BYE has none).

- [x] 4.3 `gpt_write_one()` in `kernel/src/gpt.c` (one partition, protective MBR, both headers): builds clean on three ISAs; checked on the host (a throwaway harness, not in the tree) -- 600 MiB and 32 MiB blank images and the pair's used Zuse stick each give one identity partition, `gpt_read` reads it back, `sfdisk --verify` clean. Not yet called.
- [x] 4.4 `sk_v4_identity_offer_wait()` / `sk_v4_identity_recheck_offered()`: a stick offered, not attached, while a mint waits (`g_mint_waiting`, `g_offered` in `sk_v4_identity.c`; any stick not this system's and readable -- blank, foreign or a bad table; ends on a stick, a key, or the system stick leaving). Builds on three ISAs; not yet called.
- [x] 4.5 `sk_v4_mint.c`: the flow -- plug-in line, size line, `YES`, GPT, zeroed, minted, read back, marker. Builds on three ISAs; not yet called. The gate gained a **spare**: the last stick turned away as not this system's (or handed back by a refused mint) is offered first by the next mint (for `mint_zuse_refuse`: "a second `MINT-ZUSE` is offered again"); and accessors `sk_v4_identity_stick_in/offered_present/release_offered/marker/set_marker`.
- [ ] 4.6 `MINT-ZUSE` in `sk_v4_words[]` (request 2): word_count 317 -> 318
- [x] 4.6 `MINT-ZUSE` in `sk_v4_words[]` (request 2): word_count 317 -> 318. Builds; `mint_zuse` running on amd64 (build/t4/mint-46.txt).
- [ ] 4.7 the real Zuse stick recognised and attached after the system stick; her session
- [ ] 4.8 `mint_zuse` passes on amd64; then the other tests: `mint_zuse_refuse`, `mint_pull_system`, `zuse_stick_first`, `mint_small`, the pair's stick offered
- [ ] 4.9 regressions, full acceptance on three ISAs (new dict_hash, equal), FABRIC entry, commit
