onType used to fire complete.slash only for an argless `/command`, and Tab
replaced the whole line. Now:
- planCompletion(text) (pure, in slash.ts) routes: a `/command [args]` line →
complete.slash (the gateway completes names AND args, e.g. /details section
names); a trailing path-like word (@…, ~/…, ./…, /…, or anything with /) →
complete.path for file/dir tagging; else nothing.
- the accepted item splices ONLY its token: store tracks completionFrom (gateway
replace_from via readReplaceFrom, or the path-token start), and the composer's
Tab handler keeps the text before `from` and appends the candidate.
Tests: planCompletion (slash/path/prose/multiline) + readReplaceFrom. 69 pass.
Live-smoked: `/details ` → section dropdown (hidden/collapsed/.../activity), Tab
→ `/details hidden` (arg-only splice); `tui_gateway/` → its .py files;
`@hermes_cli/m` → m-prefixed files.
