fix(cli): skip telemetry ping and hook reminder in rtk rewrite - #4619

Summary

Skip core::telemetry::maybe_ping() and hooks::hook_check::maybe_warn() when rtk is invoked as rtk rewrite, matching the existing exclusion for rtk hook.

Closes #4615

Context & Problem

In src/lib.rs, run_cli() skips the daily telemetry ping (pings_telemetry) and the once-a-day missing/outdated hook check (hooks::hook_check::maybe_warn()) for Commands::Hook { .. }, but still runs both for Commands::Rewrite { .. }.

Shell hooks and plugin adapters invoke rtk rewrite "$CMD" 2>/dev/null before every command on the hot path. Because Commands::Rewrite is not excluded:

1. When the daily hook reminder is due, rtk rewrite prints the warning to stderr (where the hook wrapper redirects it to /dev/null or captures it in hook plumbing) and touches .hook_warn_last, silencing the reminder for the actual user-visible command that runs next.
2. rtk rewrite runs the daily telemetry check and spawns a background ping thread on a short-lived process that exits immediately after printing the rewritten command.

Solution

• Add Commands::Rewrite { .. } to pings_telemetry() in src/lib.rs.
• Add Commands::Rewrite { .. } to the !matches!(cli.command, ...) guard before hooks::hook_check::maybe_warn() in src/lib.rs.
• Extend hook_commands_skip_the_telemetry_ping in src/lib.rs and hook_entry_leaves_startup_warning_for_a_normal_command in tests/hook_warning_scope_test.rs to cover rtk rewrite.

How to Test

Verified by static code inspection of src/lib.rs, src/hooks/hook_check.rs, and tests/hook_warning_scope_test.rs; execution is delegated to the PR CI matrix:

cargo test --lib hook_commands_skip_the_telemetry_ping
cargo test --test hook_warning_scope_test
