Import Pass 30 native Locus64 source

[FreshSoftware4]

What changed

• Replaces the previous 22-package compatibility-era workspace with the eleven-package dependency-free native Locus64 workspace from Pass 30.
• Establishes canonical L64R1 RNA and L64D DNA as the only authority surfaces.
• Adds proof-producing equality, context-relative closure, direct execution and derivation, ordered L64B transport, native release construction, golden portability fixtures, and source-bound portability receipt infrastructure.
• Removes the legacy theorem, campaign, research, registry, tower, cache, policy, administration, and compatibility execution island.
• Preserves the previous repository state at tag pre-pass30-source-import-2026-07-28.

Why

The returned Pass 30 source is a completed native successor rather than an incremental patch. Importing it as one lineage-preserving replacement keeps the old implementation recoverable while preventing deleted authority mechanisms from remaining live through partial merges.

Validation

• cargo fmt --all --check
• cargo test --workspace --locked --offline
• cargo clippy --workspace --all-targets --locked --offline -- -D warnings
• legacy authority island deletion gate
• native carrier gate
• CLI hardening gate
• process contract gate
• native scale gate
• documentation coherence gate
• golden portability gate
• portability receipt contract self-test
• byte-for-byte comparison against all 191 files in the supplied source archive

The shell gate executable bits were restored after Windows ZIP extraction so Linux CI can execute them.
