feat(datapack): sort transfer links and transfer rules in ascending duration order (#783)

[AquilaXk]

Related issue

Related #783

Summary

• Problem: RAPTOR transfer relaxation in 2026 early pruning relies on walking duration monotonicity across footpaths. Transfer links and rules were previously serialized in arbitrary input order.
• Outcome: `outOfStationTransferLinks` and `transferRules` are serialized into SQLite in ascending duration order (`durationSeconds` / `minTransferSeconds`), with deterministic tie-breaking via `codepointCompare`.

Changes

• `tools/datapack/build-datapack.mjs`: Sort `outOfStationTransferLinks` by `durationSeconds` ascending and `transferRules` by `minTransferSeconds` ascending before SQLite batch insertion.
• `tools/datapack/build-out-of-station-transfer-asymmetry.test.mjs`: Added deterministic unit test verifying duration-ascending serialization.

Scope

Included

• Duration-ascending sort for `outOfStationTransferLinks` and `transferRules` during SQLite packaging.

Excluded

• Schema changes or catalog version bump.

Verification

Check	Result / Evidence
Focused test	`node --test tools/datapack/build-out-of-station-transfer-asymmetry.test.mjs` (5/5 pass)
Required CI	`npm test` (198/198 pass), `npm run check:fragment` (Preflight Gate PASSED)
Live / release operation	Not required — reason: data build logic enhancement

Not run

• Check: None
• Reason: N/A
• Rerun owner / condition: N/A

Risk

• Level: Low
• Main risk: None, order-preserving sort with fallback to ID.
• Data / artifact / provenance impact: None
• Failure behavior: Standard Node.js error handling

Rollback / Recovery

• Rollback or recovery: Revert commit
• Existing artifact / schema compatibility: Compatible
