Greptile Summary

This PR introduces a per-tool install_before option in mise.toml, allowing users to override the global install_before setting on a per-tool basis. The precedence is: --before CLI flag > per-tool install_before > global install_before setting.

Key changes:

• ToolRequest::resolve() now owns the full three-tier precedence logic. The global Settings::get().install_before fallback was moved here from each CLI command, and the new per-tool lookup (self.options().get("install_before")) is inserted between the CLI and global tiers.
• CLI commands (install, upgrade, use) each have their get_before_date() trimmed to return only the CLI --before flag value; the settings fallback is no longer duplicated across all three.
• EPHEMERAL_OPT_KEYS gains "install_before" so the option is not persisted to the lockfile/manifest, which is consistent with it affecting only version resolution and not tool identity.
• E2e tests cover all three tiers of the precedence chain using jq as the test tool.
• Documentation in both tips-and-tricks.md and settings.toml is updated with an example and precedence note.

The refactor is clean and the logic is easy to follow. As an implicit side-effect, any caller of ToolRequest::resolve() that previously did not go through a CLI get_before_date() (e.g. is_installed()) will now also apply per-tool and global install_before settings. This is semantically correct — if a user has configured a date window for a tool, "is this tool installed?" should resolve with the same window — but it is worth noting as a behaviour change beyond the pure CLI paths.

Confidence Score: 5/5

• Safe to merge; no P0/P1 issues found and prior review concerns have all been addressed or are tracked in existing threads.
• All remaining observations are P2 (style/cleanup) and have already been captured in prior review threads. The core logic is correct, the precedence chain is well-tested, and the refactor properly centralises the settings fallback in ToolRequest::resolve() without introducing regressions.
• No files require special attention. The minor missing rm -f mise.toml cleanup in e2e/cli/test_install_before is already tracked in a prior thread.
