When a tool returns nothing useful, the row should be silent — the title
("Search Files", etc.) already tells the user what happened. Counting the
fields in an opaque payload is engineer-noise.
`formatToolResultSummary` and `minimalValueSummary` now return '' for
empty arrays / records / unrecognized values; tool-fallback already hides
the detail section when its body is empty.
- chat-messages: match tool rows by overlapping query/context/preview values
so preview-first `tool.progress` rows reliably adopt later stable-id
`tool.start` payloads instead of spawning ghost rows or mis-merging
parallel same-name calls; preserve prior args/result across phases.
- tui_gateway: emit full args + parsed result on `tool.start` / `tool.complete`,
drop redundant `tool.started` re-emit from `tool.progress`.
- electron/main: prefer SOURCE_REPO_ROOT before PATH `hermes` in dev so
local backend edits actually run; split hardening helpers into
`electron/hardening.cjs` with tests.
- thread/tool UI: one-shot enter animation keyed by stable ids, braille
spinner for running rows, Cursor-like disclosure rows, drill-down +
duration/count formatting via new tool-fallback-model.
- composer: extract `text-utils`, drop liquid-glass overrides.
- right-rail: split preview-pane into preview-console / preview-file.
- runtime: incremental external-store runtime + runtime-readiness gate;
onboarding store + tests; route-resume hook test.
- regression tests for live tool reconciliation (parallel tools, id-less
progress, preview-first rows, structured args/results).
