refactor!: remove dead packages with no importers

Delete 30 packages that nothing imports, are not referenced by CI or
scripts, and are not documented as active seams:

deps, engine/async, engine/code, engine/prompt, engine/trajectory,
fastcopy, feature/ide, feature/voice, hunktracker, localize, magicdocs,
observability/{alerts,conformance,logfield}, preset, profile,
system/{bus,retention,shutdown}, task, tools, container, bench, tui/diff,
filestate, gitsnapshot, lockutil, intelligence/harness, system/cron, and
the unused root context/resilience/system files.

Kept: context/repomap (used by cmd/options.go), resilience/{health,retry,
ratelimit} (used by engine + verify-milestone.sh), and testaudit (CI
package-boundary guard).

Drop the README adopted-capabilities rows and doc references for the
removed packages.
