feat: v0.2.5 — redeploy via build_stream (proper DSM image pull)

Browse Source 
Replace the delete-before-start workaround with the real mechanism:
SYNO.Docker.Project/build_stream is what the DSM "Erstellen" button calls
(confirmed via DevTools). It pulls updated images and starts the project.

DsmClient.trigger_build_stream(project_id): fires a streaming GET to
build_stream, reads the first SSE chunk to confirm DSM accepted the
request, then closes. ReadTimeout is swallowed (build running server-side).
Immediate JSON error responses are parsed and raised as SynologyError.

redeploy_project simplified from 4 steps to 3:
  1. Stop (skip for STOPPED, suppress for BUILD_FAILED)
  2. trigger_build_stream — DSM pulls images + starts project
  3. Poll for RUNNING (timeout raised from 30s → 5min for large pulls)
build_stream errors are now fatal (abort with clear message).

Removes _read_compose_images_for_project, _try_delete_image and their
json/yaml/re imports — no longer needed.

## [0.2.5] - 2026-04-21
### Changed
- `redeploy_project`: Replaced the delete-before-start image workaround with
`SYNO.Docker.Project/build_stream` — the programmatic equivalent of the DSM
"Erstellen" (Build) button, confirmed via browser DevTools capture.
New 3-step flow for all project states:
1. Stop (skipped for STOPPED; error-suppressed for BUILD_FAILED)
2. `build_stream` — DSM pulls updated images and starts the project via SSE
3. Poll for RUNNING (timeout raised from 30 s to 5 min to accommodate image pulls)
`build_stream` errors are now fatal (abort the redeploy with a clear message).
### Added
- `DsmClient.trigger_build_stream(project_id)` — fires a streaming GET to
`SYNO.Docker.Project/build_stream`, reads the first SSE chunk to confirm DSM
accepted the request, then closes the connection. The build continues
server-side. Handles immediate JSON error responses; swallows `ReadTimeout`
(stream still open = build running).
## [0.2.4] - 2026-04-21
