* chore: remove code unreachable on every supported platform

The Security and code health job's advisory deadcode step reports 152
unreachable functions on main. Running the same check under GOOS=linux,
windows, and darwin shows 13 of those are false positives whose callers
live in windows build-tagged files, so only functions unreachable on all
three platforms are touched.

Functions with no references anywhere are deleted, including the
internal/reasoning package, which nothing imports. Functions that only
tests reference move into per-package export_test.go files so tests keep
their seams while the production binary sheds the code. Test call sites
of deleted convenience wrappers are ported to the live APIs (scoped tool
constructors, tools.DeferredSource, FinishReason checks).

Kept despite the report: cron.Store.Runs (only reader of runs.jsonl,
which production writes), and agenteval.TraceEventKeys and
MissingTraceEvents (used across packages by the trace contract test).

* docs(config): correct ValidateFile's errors.As claim

Message is a flattened string (.Error() already called on the parse
error), not a wrapped error, so callers can't recover the concrete
json error type via errors.As. Fix the comment to match.

* chore(trace,skills): drop obsolete Sink adapters and fix stale doc references

The dead-code pass removed the Emit methods but left Sink, NDJSONSink, and
TextSink exported with a contract nothing implements; remove the types with
their contract. Also remove the stray blank line at EOF of trace.go flagged
by gofmt, and update skills package docs and HOW_ZERO_WORKS.md to stop
directing callers to DiscoveryRoots/Duplicates, which are now test seams.

* chore: clean up remaining review nits on dead code removal

Replace a pointless fmt.Errorf(...%w...).Error() with fmt.Sprintf
using %v, since the wrapped error was discarded immediately anyway.
Remove a comment block that was duplicated verbatim.

* docs(skills): drop remaining references to test-only List/Get

Load and MergedSkills comments still named List/Get as production
entry points after they moved to export_test.go. Point callers at
Load and ListFromRoots instead.

* chore: remove now-unreferenced export_test.go seams

execSessionManager.len() and likelySandboxDenied/sandboxDenialKind had
no remaining callers after the sandbox unify-command-execution rebase;
the production code they wrapped for tests no longer exists.
