vocab: email (0x0B05, IAM domain, OGIT ogit:Email) + SpearPort 0x000A; drop count fuses

[AdaWorldAPI]

What

email = 0x0B05

• In the Auth/IAM domain (0x0B), the next id above auth_ory_keto (0x0B04).
• Source: OGIT ogit:Email (SGO entities/Email.ttl).
• Builder email() registered in ogar-class-view.

SpearPort, app prefix 0x000A

• Aliases:
  • Email/Message → email
  • Document/DriveItem → the existing document (0x080B)
• So SpearPort::class_id("Email") gives 0x0B05_000A.

Global count fuses removed, per HOTPLUG-MIGRATION-GUIDE.md:

• count_fuse_matches_lance_graph_ogar_mirror (ogar-vocab).
• The class_ids::ALL.len() pin in capability_registry.rs.
• Drift is now caught two ways: per plug (MirrorDrift on bind), and by the lance-graph mirror parity test. A global count no longer does it.

Docs: docs/APP-CLASS-CODEBOOK-LAYOUT.md gets a row for 0x000A Spear.

Earlier pushes on this branch

The first push minted a new Mail domain (0x05XX) with invented mailbox/mail_message concepts and bumped the count pins in lockstep. That broke the hot-plug pattern, and the concepts had no OGIT source. It is all gone: there is no new domain, 0x05XX is unassigned again, and the one concept is OGIT-backed and sits in IAM.

The ordering check in the test is now a const assert, after clippy assertions_on_constants failed downstream.

Verification

• CI is green: cargo check + test, clippy -D warnings, fmt --check.
• Locally:
  • cargo clippy --workspace --all-targets -- -D warnings is clean.
  • ogar-vocab (167 tests), ogar-class-view, ogar-rbac and the adapters pass.
• The lance-graph mirror parity passes against this branch.

Merge order

• The paired mirror row, lance-graph #1419, is already merged. lance-graph-ogar builds against OGAR main, so until this PR merges, lance-graph's mirror has an email row that OGAR main lacks. Merging this closes that gap.
• Spear Coordination: OGAR cross-session stance + 3 open decisions + Sprint 7 grill-#9 correction #6 goes after this PR.

📝 Walkthrough

Walkthrough

The vocabulary assigns domain 0x05XX to Mail and adds the canonical email concept. Spear aliases map mail and document names to canonical IDs. The class-view registry includes email.

Changes

Email vocabulary

Layer / File(s)	Summary
Define the Mail domain and email concept crates/ogar-vocab/src/lib.rs	The 0x05XX range maps to Mail. The public EMAIL constant and email() builder are added, with tests for domain mapping, ID resolution, and the unchanged 0x06XX assignment.
Map Spear aliases and document the allocation crates/ogar-vocab/src/ports.rs, docs/APP-CLASS-CODEBOOK-LAYOUT.md	SpearPort maps mail aliases to EMAIL and document aliases to DOCUMENT. Its test checks the composed render ID. The allocation table records Spear's prefix and core domain.
Register email as a canonical class crates/ogar-class-view/src/lib.rs, crates/ogar-vocab/src/capability_registry.rs	The class-view registry includes email(). The capability registry test expects 99 class IDs.
