kevinveenbirkenbachandClaude Opus 5.5 5142d56503 perf(lint): lint only files changed since origin/main and run ansible-lint once
Local lint runs hand the container the files changed since the merge-base with INFINITO_LINT_DIFF_BASE; a changed tool config or shared lint script, CI, or a missing base fall back to the full run. autoformat records a content stamp after a clean ansible-lint --fix, so lint-ansible skips the second pass on an unchanged tree. shellcheck and sqlfluff check in parallel.

# Param lint_diff_active <ansible|javascript|markdown|mermaid|shellcheck|sql>: succeeds when LINT_DIFF_FILES names a list and none of its files is configuration of that tool or a shared lint script.
# Param lint_diff_files <regex>: prints the listed files matching <regex> that still exist, one per line.
