feat(LeaguesToolkit): add Toci's Gem Cutter

[mdp18]

Summary

Adds a Toci's Gem Cutter section to the Leagues Toolkit plugin.

What it does:

• Walks to Toci in Aldarin (Varlamore)
• Opens the shop and mass-clicks "Buy 1" on the selected uncut gem at 100-250ms random intervals until the inventory is full or the shop runs out (breaks on 2 consecutive misses)
• Closes the shop, uses chisel on an uncut gem, presses SPACE to select "All" in the "how many to cut?" dialog, waits until cutting finishes (via `!isGainingExp || !hasItem(uncut)`)
• Reopens the shop and rapid-sells each cut gem from the bottom inventory slot at 100-250ms intervals
• Shop stays open across sell→buy transitions to eliminate wasted UI cycles
• Auto-banks for coins when below a configurable minimum (supports Bank Heist briefcase for Leagues)

Config (new "Toci's Gem Cutter" section, collapsed by default):

• Enable toggle
• Gem dropdown: Sapphire (20 Crafting), Emerald (27), Ruby (34)
• Min coins to keep (default 10,000) — auto-banks below this
• Use Bank Heist briefcase toggle

Plugin version bumped to 1.1.0.

Test plan

• Stand next to Toci with chisel + coins, enable gem cutter, verify buy → cut → sell loop runs smoothly
• Verify buying stops when inventory fills without trying extra clicks
• Verify cutting waits for all gems to finish before moving to sell
• Verify shop stays open when transitioning from selling back to buying
• Deplete coins below min, verify it walks to bank (or uses briefcase) and withdraws
• Verify stop conditions: low Crafting, no chisel, no coins in bank
