- Around line 23-36: Add "hook-not-found" to the AUTO_UPDATE_SKIP_COMMANDS list
so automatic update eligibility skips this shell integration command, preserving
the existing behavior for all other commands.

Instruction countsNothing was compared, and so nothing was gated. No series appears on both sides: either the base has no measurements recorded, or the two were measured on different runner classes, which are deliberately not comparable — counts shift between machine types by more than a real regression does. New, nothing to compare against: Only instruction counts gate. Wall clock is shown for context — on identical hardware it moves 4-20% run to run. Measured by tak — instruction-counted CLI benchmarks, stored in this repository's git notes.

- Around line 19-21: Update the Homebrew comparison in the installation
documentation to either add a credible source and methodology defining the
measured speed and size scope, or replace the exact “20–30% slower” and “about
40% larger” claims with appropriately qualified, non-quantified wording.

Note
Medium Risk
Touches CLI startup and binary replacement (self-update + re-exec), which can affect every command if enabled. Risk is moderated by default-off, global-only settings, and multiple skip conditions (CI, offline, non-interactive, ineligible commands).
Overview
Adds opt-in automatic self-updates so mise can replace itself before eligible interactive commands, then re-run the original invocation with the new binary.
New global-only settings:
auto_update(default off) andauto_update_check_duration(default7d). Updates skip plugins, are throttled and lock-serialized, and are gated off in CI, offline/prefer-offline, non-interactive sessions, packager-disabled installs, and shell-integration commands (hook-env,activate,version, etc.). Failures are non-fatal.mise version/--versionandself-updatenow hint users toward auto-update or the official optimized binary (including Homebrew vs mise.run). Docs and schema are updated to match.Reviewed by Cursor Bugbot for commit dc55546. Bugbot is set up for automated code reviews on this repo. Configure here.
