Adds DENO_CACHE_MAX_SIZE to the special-environment-variables table. Notes the LRU-by-mtime trim behavior, the supported size suffixes (B/K/KB/M/MB/G/GB/T/TB, case-insensitive, fractional), and which subcommands trigger the trim. Refs denoland/deno#32932

There was a problem hiding this comment.
Single-row addition to the env-variables table. Description matches the upstream PR linked in the body — mtime-based trimming after cache-writing subcommands, suffix grammar (B/K/KB/M/MB/G/GB/T/TB, case-insensitive, fractional) reads correctly.
No check-runs reported on this head SHA — looks like CI doesn't auto-fire on PRs targeting the 2.8 release branch. Holding approval until CI is green.

#3081addsNODE_EXTRA_CA_CERTSto the same table a few rows up; whichever lands second will need a trivial rebase.
