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.
Move the shared module-reload policy into dsh-base by inserting its HMR row disabled, then remove the redundant disabled overrides from Web, headless, SDK, and ACP. No shipped profile enables server module reload; live profile patch watching continues through the launcher-owned config-only fallback, and browser client HMR remains a separate mechanism.
A later profile layer can opt into source-module reload explicitly with disabled: false while retaining the base root configuration. Composition tests cover every shipped mode and the explicit enable path, and the bundle references plus launcher Agent Notes document the resulting ownership and safety rationale.
