docs: align public surface with shipped interfaces

[localai-org-maint-bot]

Summary

• fix the README quickstart to invoke the shipped vllm-server binary
• update README and usage docs from ABI v10 to the current ABI v17 surface
• document the conditional embeddings and audio-transcription routes
• distinguish 35 registered architectures from the 27 correctness-gated text-generation architectures
• scope the passing Qwen3.6-27B throughput claim and badge to unsloth revision 890bdef7, while keeping NVIDIA ModelOpt 27B and current 35B gaps visible
• add the durable positioning rule that public claims, including badges, distinguish registered from gated support and name the exact benchmark checkpoint/workload

Closes #342.

Source anchors

• examples/CMakeLists.txt: target server has OUTPUT_NAME vllm-server
• include/vllm.h: VLLM_ABI_VERSION 17 and the v11-v17 additions
• src/vllm/entrypoints/openai/api_server.cpp: conditional embeddings/transcription route registration
• docs/FEATURES.md plus scripts/check-supported-models.py: 35 registered architectures and the gated distinctions
• docs/BENCHMARKS.md: passing unsloth@890bdef7 grid vs speed-pending ModelOpt/current 35B grids

Verification

Passed on immutable head e91fb3fa372bbf38c645252af7f57b83bd77b4da:

• python3 scripts/check-readme-structure.py
• python3 scripts/check-public-doc-tables.py
• python3 scripts/check-supported-models.py
• python3 scripts/check-surface-coverage.py
• python3 scripts/check-doc-checkpoint.py --base 5812b8b6 --head HEAD
• git diff 5812b8b6..HEAD --check
• focused stale-claim scan, including scratch mutation and byte-identical restoration
• independent fresh review: PASS after one badge-scoping finding was fixed and re-reviewed

The box has no CMake executable, so the CPU configure/build and vllm-server --help execution from the spike could not run; no installation or download was attempted. The binary name is instead verified directly from CMake's OUTPUT_NAME and its registered test_server_help command. Repository-wide readiness also retains two unchanged baseline failures: CMake-dependent check-test-registration, and unrelated audit-live-rows debt.

This branch conflicts with main because #364 and #374 removed three shared record surfaces. It is a one-time cost for every branch that was in flight, and the resolution is mechanical — nothing this PR measured or decided needs revisiting. I can't push to your fork, so here is the exact recipe:

git fetch origin main && git merge origin/main

Then, per conflicted file:

File	Resolution	Why
scripts/check-public-doc-tables.py	git checkout origin/main -- scripts/check-public-doc-tables.py	The STATUS_RATCHET["chars"] key is gone. It was a byte count of docs/STATUS.md stored in the checker, so every PR that touched STATUS had to re-pin it. Your re-pin only existed to pay for your own STATUS edit; dropping it loses nothing.
.agents/NOW.md	git checkout origin/main -- .agents/NOW.md	The per-row live-claims table is gone. The live position is derived now — run scripts/now.py. Your row's next step belongs in your row's own spec under a ## Now heading, which has one writer and cannot conflict.
.agents/coordination.md	keep both sides	New claims go in .agents/claims/CLAIM-<ID>.md, one file per claim. The legacy table still parses, so an existing row there is still valid.
.agents/roadmap_v1.md	keep both sides' rows	The issue table is now sorted by row ID. Union both sides and re-sort; do not drop anyone's row.
.agents/benchmark-record.md	union both sides	Append-only log — taking either side alone silently drops a measurement.
tests/scripts/test_check_public_doc_tables.py	git checkout origin/main -- <path>	Follows the checker above.

Anything under src/, include/ or tests/*.cpp is not part of this and is a real conflict worth reading.

Sorry for the churn — removing a shared surface makes every in-flight branch pay once. After this merge your PR stops competing with other PRs for these files entirely, which is the point.
