Complete NomadNet navigation and canonical Micron rendering

[torlando-tech]

Summary

• add complete NomadNet rngit request-link navigation with canonical var_ request semantics while excluding user-entered field_ values from reusable addresses
• preserve complete destination/path/variable addresses across copy, share, reopen, refresh, and browser history
• align Micron rendering with canonical NomadNet behavior for true colors, resets, section palettes, arbitrary nesting, bilateral margins, link color inheritance, and block reclassification
• recursively load partials and forms with first-wins defaults, cycle protection, active viewport/font metrics, and zero-width divider fallback
• make the first cold NomadNet request wait boundedly for path resolution instead of requiring a manual retry

Authority and development approach

Behavior is aligned with canonical NomadNet request and Micron semantics. The feature was developed through red/green regression coverage spanning parser, rendering, request framing, address round trips, recursive document loading, viewport geometry, and cold-path resolution.

Verification

• static contracts on the exact head: 226 passed, 1 skipped
• focused cold-path regression on the exact head: 100/100 deterministic passes
• full iOS suite on the production-source parent: 264/264; the exact head differs only by additional Python static assertions
• earlier exact Micron feature head: 264/264
• exact production and test-hardening reviews: approved
• physical signed-device verification confirmed that the first cold request succeeds

Physical verification used a local integration artifact that also contained the separate accepted composer fix from PR #147. This PR excludes PR #147 and contains only the complete NomadNet feature stack described above.

Risk and rollback

Primary risk is behavioral compatibility across complex Micron nesting/render modes and NomadNet address/request edge cases. Regression coverage exercises canonical colors, reset behavior, recursive partials, history/reopen semantics, request payload ownership, and cold resolution. Rollback is a normal revert of this feature branch; there are no data migrations or generated artifacts.

Greptile Summary

This PR completes NomadNet request-link navigation and substantially expands canonical Micron parsing and rendering.

• Preserves request variables through navigation history, refresh, copy, share, and reopen while excluding entered form values.
• Sends canonical field_ and var_ request maps directly through the RNS request framing layer.
• Adds bounded cold-path resolution before opening a NomadNet link.
• Adds true-color formatting, section palettes, nested layout, recursive partial rendering, form-default merging, and viewport-aware geometry.
• Extends regression coverage across parsing, request payloads, navigation round trips, partials, and rendered UI behavior.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete changed-code defect established.

Request navigation, bridge framing, parsing, rendering, recursive partial loading, and shared-address handling remain internally consistent and are covered by focused regression tests.
