chore(copilot): remove the training controls feature

[waleedlatif1]

Summary

• Remove the "Training controls" toggle from general settings, along with its showTrainingControls handler
• Remove the "Train Sim" button from the terminal and the output panel (it was already inert — isTraining was hardcoded false and both callbacks were no-ops)
• Drop useShowTrainingControls, the showTrainingControls field from GeneralSettings, the user settings contracts, and the server-side settings read
• Delete /api/copilot/training and /api/copilot/training/examples plus their contracts and body schemas — nothing in the app called them
• Drop the NEXT_PUBLIC_COPILOT_TRAINING_ENABLED env var

packages/db/schema.ts is deliberately untouched — the settings.show_training_controls column stays for a follow-up contract migration, same as the scheduled-tasks removal.

Type of Change

• Chore (code removal)

Testing

tsc --noEmit, bun run lint, check:api-validation, and check:react-query all pass. Related vitest suites pass (the 3 failures in hooks/queries are a pre-existing tailwind/postcss config error on an emcn CSS module, unrelated to this diff).

Checklist

• Tests added/updated and passing

PR Summary

Low Risk
Dead-feature removal with no remaining in-app callers; user settings may still store the old column until a later migration, which is low risk.

Overview
Removes the copilot training controls feature end-to-end: internal API routes that forwarded examples and operations to the agent indexer, Zod contracts for those bodies, and the NEXT_PUBLIC_COPILOT_TRAINING_ENABLED env flag.

Settings and API surface: showTrainingControls is dropped from general settings hooks, user settings schemas, update payloads, and server-side user settings reads/defaults. The Training controls switch in workspace general settings is removed.

Terminal UI: The inert Train Sim control (database/pause icons) is removed from the workflow terminal and output panel, along with related props, env gating, and stub training handlers.

The DB column settings.show_training_controls is intentionally left in schema for a follow-up migration.

Greptile Summary

The PR consistently removes the inactive Copilot training-controls feature while deliberately retaining its database column for a later migration.

• Removes the training toggle and inert terminal/output-panel controls.
• Deletes the two training proxy routes and their request contracts.
• Removes the setting from client/server contracts, queries, and defaults.
• Removes the associated public environment variable.

Confidence Score: 5/5

The PR appears safe to merge; the retired feature is removed consistently across its UI, contracts, routes, settings flow, and environment configuration.

No concrete reachable failure remains: repository callers of the deleted routes and flag were absent, and the retained database field is safely ignored and preserved by unrelated settings updates.
