refactor(native): split the ~3.6k-line DirectModeInterceptor into route modules

[hessius]

Problem

apps/web/src/services/interceptor/DirectModeInterceptor.ts is ~3,658 lines in a single file. It is the native/Capacitor runtime's reimplementation of the entire server API (profiles, shots, analysis, recommendations, machine I/O) and is the #1 maintenance and dual-runtime parity risk in the codebase: nearly every feature change has to touch it, diffs are hard to review, and it repeatedly churns thousands of lines when helpers move around (e.g. the recent computeRichLocalAnalysis extraction).

Goal

Break DirectModeInterceptor into focused, independently testable modules without changing behavior, so future feature work and parity mirroring become surgical.

Proposed decomposition (by route family)

• interceptor/routes/profiles.ts — profile CRUD, import/export, catalogue cache
• interceptor/routes/shots.ts — shot listing/data/annotation
• interceptor/routes/analysis.ts — local analysis, ShotFacts, analyze-llm, recommendations
• interceptor/routes/machine.ts — machine status, run-shot, live
• interceptor/lib/ — already-extracted pure helpers (analyzeLlmPrompt, shotFacts, compassRules, dynamics resolvers, meanDynamicsTarget, formatters)
• A thin DirectModeInterceptor.ts that only wires the router/dispatch table to the handlers.

Constraints

• Pure refactor — no functional change; each step should be a byte-for-byte behavior move verifiable by the existing *.direct.test.tsx suites.
• Preserve dual-runtime parity with the Python server (apps/server/); keep the module boundaries roughly aligned with the server's route/service split.
• Land incrementally (one route family per PR) to keep diffs reviewable.
• No change to the insecure-context / crypto guards or Capacitor thenable-proxy handling already in place.

Definition of done

• No single interceptor file > ~800 lines.
• All existing native direct-mode tests + tsc/eslint green.
• A short module map documented in apps/web/src/services/interceptor/README.md.

Deferred from 2.7.0 into the 3.0.0 epic. This refactor is subsumed by Phase 2 (core extraction) of the unified TS core + Bun server plan: DirectModeInterceptor decomposes into packages/core/handler.ts + per-route modules consumed by both the browser interceptor and the Bun server. Doing it standalone in 2.7.0 would be throwaway work, so it moves here to be done once with core-aligned module boundaries.

Done in the v3.0.0 line (PR #561). The ~3.6k-line DirectModeInterceptor was fully removed and its logic reimplemented once in @metic/core (packages/core), split into the core handler plus route families (profiles CRUD, shot history/analysis, dial-in, annotations, pour-over, recommendations, profile generation, image-proxy, system meta, settings), consumed by both the browser/native app and the Bun server. Parity covered by the core contract-test suite.
