Stabilize awesome-lint CI and reduce README lint noise to actionable checks

[Copilot]

awesome-lint in CI was failing on README.md with a high-volume error set, obscuring actionable issues and blocking the workflow. This PR makes lint behavior deterministic and narrows suppressions to expected false-positive categories for this repository’s matrix-style README.

• CI reproducibility

  • Pin the workflow command in .github/workflows/awesome-lint.yml from floating npx awesome-lint to a fixed version (2.3.0) to prevent behavior drift across releases.

• README lint policy tightening (not blanket suppression)

  • Replace broad/global suppression with a targeted top-level disable for high-noise rules only:
    • table-pipe-alignment, table-cell-padding, double-link, awesome-spell-check
  • Add an inline rationale for these remaining suppressions (dense tables, repeated canonical links, acronym/proper-noun-heavy content).

• Structural/content fixes to keep wider rule coverage active

  • Convert non-resource bullet prose into paragraph text where needed.
  • Remove heading punctuation that violates lint rules.
  • Normalize heading levels to avoid multiple top-level heading violations.
  • Fix bracketed text that was parsed as an undefined reference.
  • Scope awesome-license suppression to the License block only.
