feat: add Trading Bot API group

[troycdc]

Summary

Adds the new Trading Bot API division as a first-class bot CLI group and MCP service, enabling automated bot management through the existing schema-driven architecture.

New commands

cdcx bot create <bot_type> --notify-on-bot-change --settings '{...}'
cdcx bot terminate <bot_id> --bot-type <type>
cdcx bot update <bot_id> --bot-type <type> [--settings '{...}']
cdcx bot pause <bot_id> --bot-type <type>
cdcx bot resume <bot_id> --bot-type <type>
cdcx bot list --bot-types DCA,GRID --state RUNNING
cdcx bot executions <bot_id>

What's wired up

Layer	Change
Parser	"Trading Bot API" tag → "bot" group, private/bot/ prefix stripping, command name derivation
Safety	terminate = Dangerous, create/update/pause/resume = Mutate, get-* = SensitiveRead
Overlay	schemas/apis/bot.toml — renames (create, list, executions), positional args (bot_type, bot_id)
MCP	"bot" service group registered, included in "all"
Config	("bot", "Trading bot management") in MCP_SERVICE_GROUPS
Tests	Unit tests for tag mapping, command derivation, safety tiers, MCP tool generation; fixture endpoints added

Bot types supported

DCA · TWAP · GRID · FUNDING_ARBITRAGE

Complex settings objects are passed via --json '{"settings": {...}}'.

How it activates

The production OpenAPI spec at exchange-developer.crypto.com does not yet include these endpoints. Once published, running cdcx schema update (or waiting for the 24h auto-refresh) will pull the spec and the bot group appears automatically — no binary update needed.

For testing now: CDC_OPENAPI_URL=https://exchange-developer-dev.x.3ona.co/exchange/v1/openapi/ points to the dev spec which already has the 7 bot endpoints.

Test plan

• cargo build — compiles clean
• cargo test — 328 tests pass (new bot-specific tests included)
• cargo clippy — no warnings
• cdcx bot --help shows all 7 subcommands with correct descriptions
• cdcx bot list --bot-types DCA --state RUNNING --dry-run dispatches correctly
• cdcx bot terminate 123 --bot-type GRID --dry-run dispatches with Dangerous tier
• MCP tool names: cdcx_bot_create, cdcx_bot_terminate, cdcx_bot_list, etc.
