Dobromir Popov ad66f7a4d8 feat: pin runtime identity to the exact llama.cpp patch stack (DGR-025)

Derive the recipe's runtime_version axis from the DGR-027 lock manifest
(exact upstream commit + ordered patch-stack byte digest) in new
meshnet_node.runtime_pin, failing closed on any lock/series/SHA256SUMS/
patch disagreement, and enforce pin discipline on runtime_version in both
the node and tracker identity implementations.

Also repair pre-existing backlog consistency: add missing DGR-022/DGR-027
completionNotes, regenerate the DGR-022/025/027 issue projections, and
relocate three pre-DGR legacy GLM issue files to issues/legacy/. Mark
DGR-025 passes=true with evidence at evidence/DGR-025/README.md.

DGR-027: Add exact llama.cpp provenance manifest and fetch workspace

Status / triage: completed; passes: true
Execution mode: AFK
Milestone: M1
Dependencies: DGR-017
Blocks (derived): DGR-028, DGR-029, DGR-044
Labels: area:upstream, area:build, type:provenance, priority:p0, ready-for-agent
Evidence class: model-free
Hardware: none
Model: generic
Upstream: yes

Objective / description

Fresh Ralph session: read .scratch/distributed-gguf-runtime/RALPH-CONTEXT.md, source issue .scratch/distributed-gguf-runtime/issues/027-add-exact-llama-cpp-provenance-manifest-and-fetch-workspace.md, and evidence READMEs for dependencies (DGR-017) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Pin llama.cpp exactly through an in-repo manifest while fetching source only into an ignored build workspace.

Acceptance criteria

Manifest records upstream URL, exact commit, expected source archive/tree hash, license, and retrieval method.
Fetch tooling verifies identity before use and refuses an unpinned branch/tag.
Source is fetched into an ignored build workspace; no submodule, vendored source tree, or permanent fork is introduced.
Offline reuse is supported only after the cached tree’s exact identity is verified.
Applicable shared quality gates in prd.json pass, and the evidence handoff records exact commands/results, changed files, limitations, and dependency handoff.

Shared quality gates

Targeted deterministic tests pass; Python changes also pass python -m compileall packages tests.
git diff --check passes.
Default tests are model-download-free, API-credit-free, and GPU-free.
Evidence README records exact changed files, commands/results, limitations, and dependency handoff; no fabricated evidence or inherited completion credit.
Native changes pass focused out-of-tree CMake build and CTest; patch changes verify clean apply/check/reverse against the exact llama.cpp pin.
Runs are opt-in and record exact artifact/split hashes, runtime/upstream pin, backend/driver, hardware, network, commands, and raw metrics. Model artifacts use configured mounted-drive storage and never /home.
Preserve existing Transformers behavior and backend-agnostic Tracker routing/load balancing/billing/relay semantics unless an explicit versioned contract says otherwise. One scoped story commit is expected during execution, but this specification-materialization change is not committed.

Evidence handoff

Verified evidence: .scratch/distributed-gguf-runtime/evidence/DGR-027/README.md. Legacy evidence remains provenance only and grants no implementation completion credit.
