Pull request overview
This PR forward-resyncs the Chinese translation of mccall_model.md to match the current upstream lecture, including the newer JAX-based implementation and the added “Volatility” section, and records the sync state metadata.
Changes:
- Resynced
lectures/mccall_model.mdto the upstream structure/content (JAX-based code path, updated sections/exercises, GPU admonition, volatility analysis). - Added translation sync state file
.translate/state/mccall_model.md.ymlwith source SHA and sync metadata.

The resynced file keeps Chinese plot labels but reverted the import cell to the source's exact form, losing the Source Han Serif setup - Chinese in figures would render as missing glyphs.

Forward Resync: mccall_model.md
Source: QuantEcon/lecture-python.myst — lectures/mccall_model.md
Source commit:
0bfcac8This PR resyncs the translation to match the current source document.
Reason: The target is based on an entirely older version of this lecture (using Numba/jitclass instead of JAX, different code structure, older exercise sets). It contains substantial content not in source: full 'Exercise 2' with continuous distribution solution using jitclass, additional explanatory text, different exercise parameters, etc. Meanwhile it's missing major sections present in source: the entire 'Volatility' section (mean-preserving spread, lifetime value and volatility analysis), the JAX-based implementation details, comparative statics with jitted functions, and updated GPU admonition include. Since target has unique content not in source, TARGET_HAS_ADDITIONS takes priority, though there are also many CONTENT_CHANGES (missing volatility section, different library/approach, different exercise solutions).
Changes
Whole-file resync applied. The entire document was resynced in a single pass.
