merge: recover Gitea state - HQ docs, cluster setup, isogrid work
...
Merge recovery/gitea-before-force-push to restore:
- hq/ directory (cluster setup, docker-compose, configs)
- docs/hq/ (12+ HQ planning docs)
- docs/guides/ (documentation boundaries, PKM standard)
- docs/plans/ (model introspection master plan)
- Isogrid extraction work
- Hydrotech-beam: keep local DOE results, remove Syncthing conflicts

Fix mass extraction + db close order + nan handling
...
- Journal now extracts p173 mass expression and writes _temp_mass.txt
- history.get_study_summary() called before history.close()
- Optuna nan rejection: fallback to INFEASIBLE_MASS penalty
- pyNastran warning 'nx 2512 not supported' is harmless (reads fine)

Add persistent trial history DB (append-only, survives --clean)
...
- history.db: SQLite append-only, never deleted by --clean
- history.csv: Auto-exported after each trial (live updates)
- Logs: DVs, results, feasibility, status, solve time, iter path
- Cross-study queries: full lineage across all runs/phases
- --clean only resets Optuna DB, history preserved

Fix: FEM part lookup (exclude _i.prt), hole_count unit (Constant not mm), add file logging
...
- solve_simulation.py: FEM finder now excludes idealized parts, falls back to loading .fem
- solve_simulation.py: hole_count written as [Constant] not [MilliMeter] in .exp
- run_doe.py: dual logging to console + results/doe_run.log

Refactor: nx_interface uses optimization_engine (NXSolver + pyNastran extractors)
...
- AtomizerNXSolver wraps existing NXSolver + extractors from SAT3 pipeline
- HEEDS-style iteration folders with fresh model copies per trial
- Expression .exp file generation with correct unit mapping
- pyNastran OP2 extraction: displacement, von Mises (kPa→MPa), mass
- StubSolver improved with beam-theory approximations
- Reuses proven journal pipeline (solve_simulation.py)

Fix: SQLite duplicate study (load_if_exists), sampling crash with n<11, add --clean flag

feat(hydrotech-beam): Phase 1 LHS DoE study code
...
Implements the optimization study code for Phase 1 (LHS DoE) of the
Hydrotech Beam structural optimization.
Files added:
- run_doe.py: Main entry point — Optuna study with SQLite persistence,
Deb's feasibility rules, CSV/JSON export, Phase 1→2 gate check
- sampling.py: 50-point LHS via scipy.stats.qmc with stratified integer
sampling ensuring all 11 hole_count levels (5-15) are covered
- geometric_checks.py: Pre-flight feasibility filter — hole overlap
(corrected formula: span/(n-1) - d ≥ 30mm) and web clearance checks
- nx_interface.py: NX automation module with stub solver for development
and NXOpen template for Windows/dalidou integration
- requirements.txt: optuna, scipy, numpy, pandas
Key design decisions:
- Baseline enqueued as Trial 0 (LAC lesson)
- All 4 DV expression names from binary introspection (exact spelling)
- Pre-flight geometric filter saves compute and prevents NX crashes
- No surrogates (LAC lesson: direct FEA via TPE beats surrogate+L-BFGS)
- SQLite persistence enables resume after interruption
Tested end-to-end with stub solver: 51 trials, 12 geometric rejects,
39 solved, correct CSV/JSON output.
