feat(cli): add alarm suggest to recommend thresholds from meat profiles

[jongio]

What

Adds thermoworks alarm suggest <meat>, a one-shot command that recommends alarm thresholds for a cut of meat from the built-in meat profiles.

• Meat-probe high alarm is set to the profile's pull temperature.
• Pit band is centered on the profile's reference pit temperature, plus or minus --pit-band degrees (default 25).
• By-feel cuts like ribs have no numeric pull temp, so only a pit-band suggestion is shown.

The command is offline (no login or network) and suggestion-only. It never writes to a device. It prints ready-to-edit alarm set commands, and --serial, --meat-channel, and --pit-channel fill those commands in with real values.

Why

The SDK already ships the meat profiles used by doneness and plan, but there was no quick way to turn a cut into concrete alarm thresholds. This closes that gap: pick a meat, get the numbers plus the exact commands to arm them.

Usage

thermoworks alarm suggest brisket
thermoworks alarm suggest brisket --pit-band 30
thermoworks alarm suggest brisket --serial ABC123 --meat-channel 1 --pit-channel 2
thermoworks alarm suggest ribs --json

Testing

• pnpm --dir packages/cli typecheck - clean
• pnpm --dir packages/cli test - 890 passing (14 new)
• pnpm lint - clean

New tests cover the pure buildAlarmSuggestion helper (pit band math, pull-temp alarm, by-feel cuts, custom band, placeholders vs filled commands) and the alarmSuggest command (human output, aliases, JSON, flag parsing, error paths).

Closes #274
