Walkthrough

Updated help text in restic/commands.json for six forget options to clarify default value behaviour and add a docs link; adjusted wording in docs/content/configuration/sleep.md to specify that prevent-sleep applies while running commands. No behavioural or API changes.

Changes

Cohort / File(s)	Summary of Changes
Option description updates restic/commands.json	Amended description text for forget options keep-daily, keep-hourly, keep-last, keep-monthly, keep-weekly, keep-yearly to note that the default value of 0 removes no snapshots and to add a documentation link.
Documentation wording tweak docs/content/configuration/sleep.md	Clarified that prevent-sleep applies "while running commands" rather than generally; no other content changes.

Hey! Thank you for the clarification.

This file commands.json is actually generated from the restic documentation itself (after running restic generate --man).

It's going to be a bit move involved to add this message: in the documentation parser, we need to add it to the existing description from the manual.
