fix(tui): surface verbose tool details (#30225)

* fix(tui): surface verbose tool details

Emit redacted structured verbose args/results to the TUI so /verbose verbose can show full tool detail without reopening stdout, and fail closed if redaction is unavailable.

Salvages #29011.

* fix(tui): address verbose detail review

Label verbose tool failures as errors, cover forced verbose reasoning, and avoid new diff type warnings from the redaction regression tests.

* fix(tui): bound verbose tool payloads

Cap verbose tool detail text before emitting JSON-RPC events and preserve verbose results on inline diff completions.

* fix(tui): align termux argv test with gc flag

Update the stale TUI launch expectation so the Termux freshness path matches the current direct Node argv.
