Introduce render gate and chart caching

Browse Source 
Replace UI DispatcherTimer polling with a StudySnapshotRenderGate across multiple widgets to queue and apply only the latest analytics snapshot; components updated include StudyDeductionReasonsWidget, StudyEnvironmentWidget, StudyInterruptDensityWidget, StudyNoiseCurveWidget. Add StudySnapshotRenderGate implementation to coordinate rendering and monitoring leases and update subscription/lease lifecycle handling (subscribe/unsubscribe, Acquire/Dispose leases, Clear/Dispose gate). Rewrite chart controls (StudyNoiseCurveChartControl and StudyNoiseDistributionScatterChartControl) to use stable logical-time origins, split series into static vs dynamic tails, add geometry/sample caching, stable jitter/coordinate mapping helpers, and expose internal helpers & counts for testing. Add unit tests (StudyComponentRenderingTests) covering the render gate and chart behaviors (layer counts, logical X mapping, stable jitter, cache rebuild). These changes improve rendering correctness and performance by avoiding redundant renders and enabling deterministic chart layout.

# Checklist
- [ ] `release.yml` includes PDCC publish flow and does not invoke Velopack.
- [ ] `release.yml` uploads app payload artifacts for PDCC.
- [ ] S3 output path is rooted at `lanmountain/update/` (no system version prefix).
- [ ] S3 has `repo/`, `meta/`, and `installers/` outputs after a release run.
- [ ] Host update source default is `stcn` and old `pdc` values are auto-normalized.
- [ ] Host can persist PDC payload into launcher incoming directory.
- [ ] Launcher can apply PDC FileMap payload with signature/hash verification.
- [ ] Legacy signed `files.json + update.zip` path still works as compatibility fallback.
- [x] `release.yml` does not invoke Velopack.
- [x] `plonds-build.yml` uploads app payload artifacts and generates PloNDS delta/static outputs.
- [x] S3 output path is rooted at `lanmountain/update/` (no system version prefix).
- [x] CI workflow expects `repo/`, `meta/`, `manifests/`, and `installers/` outputs after a release run.
- [x] Host update source keeps compatibility (`pdc`/`stcn` normalize to active PloNDS source).
- [x] Host can persist PloNDS payload into launcher incoming directory.
- [x] Launcher can apply PloNDS FileMap payload with signature/hash verification.
- [x] Legacy signed `files.json + update.zip` path still works as compatibility fallback.
- [x] Launcher keeps rollback-capable deployments after successful update.
- [x] Manual rollback returns a structured failure when the snapshot source directory is missing.
- [ ] CI run attached proving all release matrix jobs pass.
- [ ] N-1 -> N incremental update verified on Windows x64/x86 and Linux x64.
- [ ] Rollback verification report attached.
- [x] N-1 -> N incremental update verified locally on Windows x64.
- [ ] N-1 -> N incremental update verified on Windows x86 and Linux x64.
- [x] Rollback regression tests attached in `LanMountainDesktop.Tests`.

## Stage 2 (Current Implementation Target)
- Move release publishing to PDCC + `phainon.yml` (ClassIsland-style).
- Promote PDC-distributed FileMap/object-repo as the primary incremental path.
- Use GitHub Actions PloNDS static publishing as the active incremental path.
- Keep `phainon.yml` for future PDCC parity, but do not rely on PDCC for the current release flow.
- Promote PloNDS-distributed FileMap/object-repo as the primary incremental path.
- Keep GitHub Release installers and metadata as parallel distribution.
- Keep Launcher state machine ownership (`.current/.partial/.destroy` + snapshots).
- Update source defaults to `stcn` (S3/PDC), with GitHub fallback.
- Check updates in order: NS3/PloNDS static source, GitHub Release PloNDS assets, then GitHub full installer.
- S3 object root is fixed to `lanmountain/update/` with no update-system version prefix.
- Public object URLs come from `S3_PUBLIC_BASE_URL`; do not infer them from `S3_ENDPOINT` and `S3_BUCKET`.
Expected S3 layout:
- `lanmountain/update/repo/<hash-prefix>/<hash-object>`
- `lanmountain/update/meta/channels/<channel>/<subchannel>/latest.json`
- `lanmountain/update/meta/distributions/<distributionId>/*.json`
- `lanmountain/update/installers/<platform>/<arch>/*`
- `lanmountain/update/repo/sha256/<hash-prefix>/<hash-object>`
- `lanmountain/update/meta/channels/<channel>/<platform>/latest.json`
- `lanmountain/update/meta/distributions/<distributionId>.json`
- `lanmountain/update/manifests/<distributionId>/plonds-filemap.json`
- `lanmountain/update/manifests/<distributionId>/plonds-filemap.json.sig`
- `lanmountain/update/installers/<platform>/<version>/*`
## Acceptance
- `release.yml` includes PDCC publish steps and no Velopack steps.
- `release.yml` contains no Velopack steps; PloNDS static publishing is handled by `plonds-build.yml` and `ddss-publish.yml`.
- Release jobs keep building installers for Windows x64/x86, Linux x64, and macOS.
- PDC metadata + FileMap + object repo are published under `lanmountain/update/`.
- Host can consume PDC payload (`stcn` source) and fallback to GitHub when unavailable.
- PloNDS metadata + FileMap + object repo are published under `lanmountain/update/`.
- Host can consume the NS3/PloNDS static payload and fallback to GitHub when unavailable.
- Launcher can apply both:
- legacy signed `files.json + update.zip`
- PDC FileMap object-repo payload.
- Rollback semantics remain unchanged.
- PloNDS FileMap object-repo payload.
- Rollback semantics keep both automatic failure rollback and manual rollback after a successful update.
