Robert Allan JamesandClaude Opus 5 668e36bb17 §H.12 step 1: add Session struct (type only)
include/starkernel/session.h: vm_id (VMUuid), pinned (int, authoritative
over Stadium's STADIUM_FLAG_PIN per H.10), parent (VMUuid), name (fixed
64-byte buffer), identity (embedded VMIdentity, reusing the existing
type rather than inventing a new one). No logic yet, no callers -- next
step wires the session-slot array and register/find functions.

Verified 3-arch boot to ok> (amd64/aarch64/riscv64).

/**
* session.h - Per-VM session (FABRIC-3.md §H, decided 2026-09-02/03)
*
* A session is a Stadium patron (FABRIC-3.md §H.1) -- registering a session
* IS admitting a patron to the Stadium, not a new parallel bookkeeping
* structure. This struct is the piece that sits ALONGSIDE the patron,
* referencing it by VMUuid rather than being indexed by Stadium cell index
* or grown as inline fields on StadiumPatronHeader/struct VM (deliberately
* its own header, mirroring VMUuid's/VMIdentity's own precedent -- standing
* instruction: give real-shaped data its own header and integrate as a
* field, don't grow existing structs ad hoc).
*
* Fields (FABRIC-3.md §H.2, all five confirmed 2026-09-02/03):
* vm_id -- the patron this session references.
* pinned -- session is AUTHORITATIVE over Stadium's STADIUM_FLAG_PIN
* bit (§H.10): the sole read/write path for pin state is
* session_set_pinned()/session_is_pinned() below, nothing
* else (including existing Stadium code) may touch
* STADIUM_FLAG_PIN directly.
* parent -- who birthed this session (Hera -> Hermes/Artemis, etc).
* name -- canonical human-readable name; feeds console.c's
* g_active_vm_name prefix, does not replace the
* console-binding mechanism itself.
* identity -- embedded VMIdentity (FABRIC-3.md §H.4's VM card is
* effectively VMIdentity's existing ownership check; reused
* directly here, not reinvented).
*
* Explicit user framing (2026-09-02), still true: "we're gonna be
* revisiting this part of it around and around for a while" -- treat this
* shape as a live working draft, not permanently locked.
