[Frontend][Telemetry] appVersion is hardcoded to '0.1.0' in telemetry payloads — wire it from build config

[Chris0Jeky]

What

frontend/taskdeck-web/src/store/telemetryStore.ts:158 hardcodes appVersion: '0.1.0', // Will be set from build config in future in every telemetry event payload. Nothing in the UI renders it, and the backend-reported product version (Taskdeck.Application.Common.ProductVersion → /health/live, /health/ready, CLI version) is tag-derived and correct — but a v0.2.0 build still self-reports 0.1.0 in telemetry traces, and every future release will drift the same way.

Found by the 2026-08-29 v0.2.0 release-readiness audit (finding F-8). Not tag-blocking, not user-visible.

Acceptance

• appVersion comes from build configuration (e.g. a Vite define fed by the release workflow's tag-derived version, with the same 0.0.0-dev fallback the backend uses) instead of a literal; do not hand-bump the literal to 0.2.0.
• telemetryApi contract/spec updated to assert the injected value.
• docs/platform/CONFIGURATION_REFERENCE.md or the release workflow comment records where the frontend version comes from.

Implemented in PR #2535: https://github.com/Chris0Jeky/Taskdeck/pull/2535\n\nThe frontend telemetry payload now reads VITE_APP_VERSION at Vite build time and falls back to 0.0.0-dev. Release Desktop and Release Container pass their normalized tag-derived version; Docker defaults and configuration reference are documented. Verified: telemetry/API tests 25/25, typecheck, scoped ESLint, production build, explicit injected bundle check, release-cache contract 28/28, targeted release-version assertions 4/4, docs governance, golden principles, and diff check. Full release-desktop contract remains 70 pass / 6 baseline Windows/WSL validator failures on both primary and worktree; hosted CI/workflow lint remains the final gate.

SC-10 progress (coordinator, 2026-09-06). PR #2535 merged as f6ec8f9c0 at head f743786d8 after update-branch, a fresh-context re-review against the moved base (SHIP; LOWs recorded on the PR) and a green hosted run. The frontend telemetry appVersion is now the build-stamped version in release images and desktop builds, 0.0.0-dev elsewhere.
