Remove `< /dev/null` workaround once min altimate-code version includes stdin-wedge fix

[sahrizvi]

Context

The altimate-code skill's documented invocations are about to be patched (in the companion PR) to append < /dev/null to every altimate-code run call:

altimate-code run "<task>" --yolo --output /tmp/altimate-result.md --dir "$(pwd)" < /dev/null

This is a transitional workaround for an upstream bug: altimate-code run wedges silently on inherited stdin when invoked as a subprocess (Claude Code's Bash tool, CI, Python subprocess.run(..., stdin=None)). Bun.stdin.text() waits forever for an EOF that never arrives. Full repro: AltimateAI/altimate-code#934.

The proper fix is the source-side guard in AltimateAI/altimate-code#935 — once that PR is merged and a release ships, the < /dev/null workaround is no longer needed for users on that release or later.

Action when #935 ships

Once a tagged altimate-code release containing the fix is available:

1. Identify the release version (e.g. v0.8.8 or v0.9.0, whatever ends up shipping it).
2. Replace the < /dev/null redirect in each altimate-code run invocation in skills/altimate-code/SKILL.md with a min-version prereq check in the existing "Prerequisite Check" section. Sketch:

   altimate-code --version | <semver-ge X.Y.Z check> || {
     echo "altimate-code >= X.Y.Z required (older versions wedge on inherited stdin)"; exit 1;
   }

3. Remove the HTML comments next to each invocation (they point back here).
4. Close this issue with a link to the cleanup PR.

Why not skip the band-aid and only do the min-version bump?

Until the release ships and most users have upgraded, the band-aid protects every existing user from the silent wedge. Costs ~10 characters of token tax per invocation; saves real users from a hang that takes ~5 minutes to diagnose.
