simulator.post_advance always even if no diag dump was made

📝 Walkthrough

Walkthrough

The hierarchy now raises and exports TimeNotFoundError for missing diagnostic times. Simulator.advance invokes post_advance independently of automatic dumping. Diagnostic callbacks stop cleanly when data for the requested time is unavailable.

Changes

Diagnostic time handling

Layer / File(s)	Summary
Missing-time exception and hierarchy lookups pyphare/pyphare/pharesee/hierarchy/...	TimeNotFoundError is defined and exported. Hierarchy and HDF5 lookups raise it when the requested time is unavailable.
Post-advance callback execution pyphare/pyphare/simulator/simulator.py	Simulator.advance runs _auto_dump() independently from the post_advance callback.
Callback handling for unavailable diagnostics tests/functional/tdtagged/td1dtagged.py, tests/simulator/refinement/*	Callbacks catch TimeNotFoundError and return without processing unavailable diagnostic data.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 51b36

Post-advance callbacks now run after every successful advance, including without automatic diagnostic dumps. The behavior lacks a focused auto_dump=False regression test, creating a bounded risk of future callback-execution regressions.

Explanation

The changes satisfy issue #1291 by invoking post_advance after every advance(), including when no diagnostic dump occurs or auto_dump is disabled. The diagnostic callback updates prevent expected missing-time errors.

Add a regression test for the auto_dump=False callback path.

Configure Simulator with auto_dump=False and a post_advance callback. Assert that the callback runs once after each successful advance(). This prevents the callback from becoming gated by _auto_dump() again.
