Summary

• Permission prompts abandoned with Esc record an abandoned decision instead of a synthetic deny; the action is still denied
• permission_prompt events carry the approval mode (interactive) from the approval log
• Unknown slash commands emit one bucketed slash_command event instead of none

Verification

• bun run lint passes; targeted suites pass: telemetry-product-events (24), permission gate/queue plus approval-resume/check-gate plus command registry (139)
• bun run typecheck reports one pre-existing vendor error (semver types missing from the install); check:dead-exports cannot run (ts-prune binary absent)
• Seven existing overlay-level assertions still expect Esc to resolve a synthetic deny and need updating to the abandoned contract in a follow-up

Fixes CL-9013

Closing as telemetry-only: does not improve operator-facing output, and the PR is not CI-green + trivial after the 0333 merge wave. Reopen if product telemetry is prioritized separately.
