Historical benchmark compatibility adds maintenance work ahead of v0.5.1. This change requires both release labels in new measurements to be v0.5.0 or newer and rejects older releases before fetching sources or creating worktrees.

• Remove legacy Rust API/layout adapters and missing-baseline-row exceptions. Keep the scientific input gates and require the complete selected benchmark inventory.
• Retire just performance-github-assets and the assets subcommand. Retained runs remain available for offline rendering when they satisfy the supported benchmark contract; archived artifacts are unchanged.
• Generalize the release guide beyond v0.5.0 and update the required uv version to 0.13.3.

The remaining Python script migration is tracked in acgetchell/research-repo-tools#115; this PR completes the historical-compatibility cleanup that precedes it.

Validation: just ci passed on macOS arm64, including 163 Python tests, Rust tests and doctests, linting, static analysis, benchmark builds, and examples. Regression coverage includes rejection of older releases on either side before measurement side effects, missing required benchmark rows, and offline replay of a retained v0.5.0/v0.4.6 run.

Summary by CodeRabbit

• Performance Tooling

  • New performance measurements require la-stack v0.5.0 or newer.
  • Release comparisons now require complete benchmark data and validated release pairs.
  • Retained compatible benchmark runs can still be rendered offline.

• Documentation

  • Updated benchmarking, release, and performance-tooling guidance to reflect current policies and workflows.

• Breaking Changes

  • Removed legacy API compatibility options and historical benchmark filters.
  • Removed the archive-based performance comparison command and related workflow.

📝 Walkthrough

The changes remove historical la_stack API compatibility branches from Rust benchmarks and performance tooling. Measurement planning now enforces a v0.5.0 minimum and complete selected-row coverage. The archive-assets comparison command was removed. Benchmarking and release documentation, workflow tests, and the required uv version were updated.

Changes: Benchmark and Performance Tooling

Layer / File(s)	Summary
Use current APIs in benchmarks Cargo.toml, benches/common/*, benches/comparison/tests/vs_linalg_inputs.rs, benches/exact.rs, benches/vs_linalg.rs, tests/exact_bench_config.rs	Benchmark code now calls norm methods directly and uses the rational-result wrapper accessor. Historical API configuration guards and norm adapters were removed. Exact benchmark modules, registrations, and related tests are unconditional within their parent feature gates.
Enforce measurement eligibility and coverage tooling/performance-policy.toml, scripts/performance_runs.py, scripts/tests/test_performance_workflow.py	The minimum release is v0.5.0. Measurement planning validates release pairs, uses a captured environment for both phases, and requires selected rows in both inventories. Tests cover the revised policy, planner, and retained-run behavior.
Remove release-asset comparison workflow scripts/archive_performance.py, scripts/tests/test_performance_workflow.py, justfile	The asset comparison command and recipe were removed. Local and release commands share measurement and save behavior; only release promotes saved evidence.
Update performance tooling documentation docs/BENCHMARKING.md, docs/code_organization.md, docs/dev/performance-tooling-adoption.md, scripts/README.md	Documentation now describes the release floor, complete-row requirements, retained-run handling, and revised tooling responsibilities. References to the retired asset comparison command and compatibility adapters were removed.

Release and Toolchain Maintenance

Layer / File(s)	Summary
Revise release tracking guidance docs/RELEASING.md	Release guidance now asks each release to record current publication and consumer-verification status, publisher identity, and relevant policy evidence.
Update required uv version pyproject.toml	The required uv version changed from 0.13.2 to 0.13.3.

v0.5.0 minimum unconditional: state that new measurements require v0.5.0 or
newer on both sides, and revise the later reference that currently says “before
v0.5.0” to match this policy.
