fix(architecture): add missing operational mechanics phase documentation

[TrueAlpha-spiral]

This PR adds the missing architecture/operational-mechanics.mdx file, formalizing Phase 3 (The Metabolism & The Courtroom) as defined in the TAS Architectural Manifest. It also updates the mint.json configuration to include the file in the sidebar navigation, resolving the broken link that prevented PR #16 from merging.

Code Review

This pull request introduces the 'Operational Mechanics' documentation for Phase 3 of the TrueAlphaSpiral architecture and updates the navigation configuration in mint.json. Feedback includes a recommendation to add a 'Core Artifacts' section and use numbered headings in the new documentation for consistency with previous phases, as well as a request to add a trailing newline to mint.json.

[gemini-code-assist]

To maintain consistency with the documentation structure of Phase 1 and Phase 2, please include the 'Core Artifacts' section and use numbered headings for the main operational mechanics as defined in the Architectural Manifest.

## Core Artifacts

*   `RECURSIVE_CONTEXT.md`
*   `mnist_test.csv`
*   `Fusion Reactor Safety and Truth Architecture`

## 1. The Phoenix Protocol

The Phoenix Protocol ensures architectural continuity and enforces the P2 Hard Rollback across a 4-tiered SLA. It provides the mechanism for the system to recover gracefully from stress events while maintaining the strict cryptographic invariants defined in Phase 2.

## 2. The Triadic Knowledge Engine

The Triadic Knowledge Engine integrates the DecisionStrainGauge to evaluate truth pathways under dynamic load. This mechanism measures the tension between operational efficiency and epistemic certainty, ensuring that knowledge claims do not exceed the structural capacity of the system to prove them.

## 3. The Falsification Surface

The core proving ground where lineage-preserving accuracy is tested. The MNIST Torsion Bench serves as the courtroom for empirical falsification, systematically applying stress to knowledge claims to eliminate scaled ambiguity.

[gemini-code-assist]

The file is missing a trailing newline. It is a best practice to include a newline at the end of files to ensure compatibility with POSIX tools and to avoid 'No newline at end of file' warnings in version control systems.
