fix(evolution): align repository overview and refresh state

[jhinpan]

Summary

• align README, skill guidance, citation, and repository metadata with the active gfx942/gfx950 scope and maintainer-controlled workflow
• distinguish complete baseline harvests from rolling per-source discovery and preserve conservative watermarks after successful empty scans
• allowlist the canonical AMDGPU guide path so future updates are discovered, with regression coverage and refreshed manifest provenance
• document actual file/line budgets, Draft creation behavior, CI triggers, administrator bypasses, and freshness ownership

Test plan

• python3 -m pytest tests (57 passed)
• python3 scripts/validate.py (0 errors)
• retrieval and answer evaluations
• artifact provenance and corpus manifest checks

Merge contract

• Every branch commit is authored and committed by Jin Pan <jin.pan@amd.com> with no co-author trailers.
• Use rebase merge so the exact author identity is preserved on main.

Reviewer's Guide

Aligns documentation, evolution tooling, and source registry with the active CDNA scope and maintainer-controlled workflow, tightens CI/quality contracts, and updates discovery state handling for empty initial scans and allowlisted AMDGPU guide paths.

File-Level Changes

Change	Details	Files
Clarify corpus freshness, evolution workflow, and maintainer-controlled boundaries in top-level docs and skill metadata.	Reworked README and SKILL.md corpus freshness sections to distinguish baseline harvest cutoffs, per-source incremental discovery, and manifest inventory. Documented that automation creates a single rolling Draft evolution PR from a disposable clone, with maintainers responsible for acceptance and merges. Expanded maintenance tooling description to mention sources.yaml as the canonical registry, file/line budgets, MI355 evaluation behavior, and CI trigger conditions including admin bypasses. Updated citation title to match the AMD CDNA-only scope and refreshed wording around self-evolution and untrusted upstream data.	README.md SKILL.md ops/evolution/README.md VERIFICATION.md CITATION.bib
Adjust evolution discovery behavior to persist conservative watermarks on empty initial scans and align sources/manifest state.	Modified run_discovery to write a durable evolution-state watermark when the first successful scan finds no changes but has a caller-provided since bound. Extended evolution-state.yaml with initial safe-since entries for rocm-triton and rocm-flash-attention. Updated corpus-manifest.yaml source_registry_sha256 to match the new sources registry contents.	scripts/evolve/discover.py data/evolution-state.yaml data/corpus-manifest.yaml
Allowlist the canonical AMDGPU optimization guide path in the sources registry and add regression coverage for path-based decisions.	Added docs/amdgpu_kernel_optimization_guide.md to the include_paths for the amdgpu-optimization-guide source in sources.yaml. Introduced a test ensuring that changes to the canonical AMDGPU guide path produce a deferred candidate decision with an allowlisted-path relevance reason.	data/sources.yaml tests/test_evolution.py
Tighten evolution tooling semantics and PR review contracts.	Updated the evolve package docstring to emphasize maintainer-controlled evolution tooling. Relaxed draft_pr.py wording so the rolling PR is described as created as Draft and explicitly assigns acceptance and merge decisions to maintainers, while treating generated checks as preconditions for maintainer acceptance. Clarified daily evolution service README to state it never pushes to main or performs approvals/merges, and that maintainers own those decisions.	scripts/evolve/__init__.py scripts/evolve/draft_pr.py ops/evolution/README.md
