Rename the tool-presentation transport from code-mode to ptc everywhere
that is not written into session logs: the mode config value becomes 'ptc',
the preset directory/id becomes ptc, the demo becomes demo:ptc, the
dispatch waterfall becomes tools/ptc-dispatch-log (types PtcDispatch*), the
prompt rule becomes tools:ptc-only, source/test files become ptc.ts etc.,
and prose says PTC mode / PTC 模式. The session-persistent vocabulary
(durable events tool/code-dispatch*, logged plugin name tools-code-mode,
sub-call id segment :code:) intentionally stays and moves in the stacked
persistence PR, which is blocked until the SESSION_FORMAT_VERSION v0→v1
migration lands with it. run_code, its code parameter, CodeSdkLanguage,
CodeRunFailedError, the dsh-code-runtime family, third-party codex names,
and frozen archived notes keep their names.
Candidate rows lead with domain icons instead of localized text
prefixes; pointer and keyboard share one reducer-owned highlight (last
input wins); drillable folder rows reveal a localized Browse-folder +
Tab keycap hint with the library chevron; pending sources render
skeleton bars; the menu spans the composer card. The editable @dir/
text decorates color-only — the domain icon now belongs exclusively to
the settled reference chip. Composer placeholders advertise / and @,
and the zh copy for commands is unified to 指令.
