Fixes #737

Per-item summary of the acceptance checklist:

• docs/deployment.md:391-403 generate --app-path — confirmed against src/azure_functions_openapi/cli.py: there is no --app-path. Replaced both snippets with --app function_app:app. Executed both (JSON and YAML) against examples/report_jobs; the JSON run emits all three /api/reports* paths.
• llms.txt / llms-full.txt version — nothing in the repo syncs this field, so bumping 0.27.0 to 0.29.0 would just re-stale next release. Replaced the hard-coded version with a pointer to PyPI.
• docs/assets/screenshots.yml — labeled historical rather than faking a recapture: a manifest header documenting that all nine captures are from 0.21.2 (2026-08-15), plus status: historical on each entry. scripts/check_screenshots.py --strict still passes.
• SUPPORT.md — "3.11 and above" is now 3.11-3.14 (>=3.11,<3.15), matching requires-python.
• docs/development.md, docs/contributing.md — removed Black (ruff does formatting and linting); replaced the duplicated tool-version tables with a pointer to .pre-commit-config.yaml and pyproject.toml (the two pins disagreed with each other and with the docs); corrected both Makefile tables against the real targets; documented the enforced 95% gate (fail_under = 95) in place of the stale 85% target, including docs/testing.md; and corrected the review claim — branch protection has required_approving_review_count: 0, so the CI checks are the merge gate, not an approval.
• docs/usage.md — dedented the "Non-standard HTTP methods (OpenAPI 3.2)" heading and its first paragraph so it renders as ### instead of a code block.
• ecosystem links — azure-functions-{langgraph,validation,logging,doctor,scaffold} (no -python) only redirect rather than resolve directly; repointed to the canonical *-python repos in docs/architecture.md, docs/deployment.md, and DESIGN.md. The README tables were already correct. azure-functions-durable-graph-python and azure-functions-knowledge-python are marked retired upstream and are correctly absent.
• CONTRIBUTING.md CISA link — confirmed 404; replaced with the GitHub advisory for CVE-2025-30066 (GHSA-mrrh-fwg8-r2c3, 200).
• docs/installation.md — explained that 4-python3.12 is an example and listed the supported tags; verified 4-python3.11 through 4-python3.14 all exist in the MCR tag list.

docs/architecture.md was touched for ecosystem links only, leaving the decorator-order content for #736.

Verification

• mkdocs build --strict — clean
• scripts/check_screenshots.py --strict, scripts/lint_mermaid.py, tools/lint_hatch_matrix.py, tools/lint_release_workflows.py, tools/lint_workflow_pins.py — all pass
• pytest — 1021 passed, 29 skipped
• every changed external URL curled: all 2xx
• no Python source changed, so ruff had nothing to check
