* ✨ Add media-processor service for image and font processing
Externalizes ImageMagick and FontForge subprocess invocations into a
separate Node.js HTTP service (media-processor/). Backend dispatches
via feature flag :use-remote-media-processing.
Key changes:
- media-processor module (TypeScript, Express 5, Sharp, FontForge/woff)
- POST /api/image/info, /api/image/thumbnail, /api/font/generate
- Resource limits: 128MP rejection, prlimit (512MB + 30s CPU)
- Streaming multipart via SequenceInputStream
- app.media split into validation (leaf), local (shell impls), remote (HTTP)
- Schema enforcement: :upload and :input schemas in validation namespace
- Configurable timeout (PENPOT_MEDIA_PROCESSING_SERVICE_TIMEOUT)
- 78 tests across 4 files (image, font, middleware, config)
- FontForge path escaping for command injection prevention
- Parallel font variant conversions with Promise.all

cleanup middleware that removes temp files on response finish/close
- Wrap sharp metadata/decoding errors as 400 validation errors instead
of 500 internal errors

* 🐛 Fix code review issues in media-processor (round 4)
- Add Zod validation constraints for config values (int, positive, min)
- Fix auth middleware to compare Buffer byte lengths instead of string lengths
- Validate requested output dimensions in generateThumbnail (crop mode)

* 🐛 Close HTTP response streams in backend media remote
- Wrap stream consumption in try/finally with .close() calls
- Add tests to verify stream closure for info, font-convert, and thumbnail

* 🐛 Fix queue slot leak on upload failures
Make releaseQueue idempotent and attach fallback listener to release
slot when response finishes. This covers Multer errors that bypass
the route handler's finally block, preventing permanent queue stall.

* 🐛 Cancel processing on timeout
Create AbortController in timeout middleware and abort signal when
timeout fires. Pass signal to Sharp and FontForge to cancel ongoing
processing and release resources when request is cancelled.
AI-assisted-by: qwen3.7-plus
* 🐛 Fix code review issues in media-processor (round 6)
- Error handler: check headersSent before writing response to prevent
ERR_HTTP_HEADERS_SENT when timeout already sent 504
- Timeout config: increase default requestTimeout from 60s to 180s to
match font processing timeout (120s) and backend request timeout
- Image processing: check abort signal before starting Sharp operations
to cancel processing when timeout fires
- Queue lifecycle: remove res.on('close', release) fallback to hold
queue slot until processing completes, preventing concurrency limit
violation when client disconnects

* 🐛 Close HTTP response stream in download-image
Wrap response body in with-open to ensure stream is closed after
writing to temp file, preventing HTTP connection leaks on repeated
URL imports.
AI-assisted-by: qwen3.7-plus
* 🐛 Close HTTP response stream on validation errors in download-image
Move with-open to wrap the entire validation and processing block,
ensuring the response body stream is closed even when validation fails
(non-2xx status, missing size, invalid media type). This prevents
HTTP connection leaks on repeated failed downloads.
Add test to verify stream closure on validation errors.

* 🐛 Pass abort signal to Sharp toBuffer for timeout cancellation
Wrap Sharp's toBuffer() with Promise.race to check abort signal during
processing. This ensures large thumbnails stop processing when the
request times out, preventing wasted CPU/memory and queue capacity.
Add test to verify abort during toBuffer operation.

* 🐛 Hold queue slot until Sharp completes and handle client disconnect
- Remove Promise.race from generateThumbnail — Sharp processing now
completes fully before queue slot is released, preventing concurrency
limit violations under timeout conditions
- Remove res.on("finish", release) fallback from queue middleware —
error handler now explicitly calls releaseQueue in all error paths
- Add res.on("close") handler in timeout middleware to abort signal
when client disconnects, ensuring processing stops early
- Add tests for client disconnect handling and queue slot lifecycle

ProcessingError on resource limit kills instead of returning null
- Validate font signatures for same-format conversions to prevent
arbitrary files from being persisted as valid fonts
- Fix concurrent mkdtemp race in upload-storage by using shared
initialization promise

* 🐛 Remove Content-Length header from multipart requests
The JDK's HttpClient rejects Content-Length as a restricted header,
causing IllegalArgumentException when sending multipart requests to the
media-processor. Remove the explicit Content-Length header and let the
JDK use chunked transfer encoding. The media-processor will use disk
storage for all multipart requests (safe default behavior).
Remove unused size computations (file-size, header-bytes, footer-bytes,
total-size) that were only used for Content-Length.
Update test to verify Content-Length is not present in request headers.

* 🐛 Fix pino ESM bundling for media-processor

avoid bundling issues with worker thread modules that reference
__dirname (not available in ES modules).

Skip storage objects touched less than 2 hours ago, matching the pattern
used by upload-session-gc. Update all affected tests to advance the clock
past the threshold using ct/*clock* bindings.
This simplifes the mental model on how it works and simplifies testing
of the related code.
This also normalizes storage object deletion in the same way as the
rest of objects in penpot (now future deletion date on storage object
also means storage object to be deleted).
This upgrade also includes complete elimination of use spec
from the backend codebase, completing the long running migration
to fully use malli for validation and decoding.
The main objective is prevent deletion of objects that can leave
unreachable orphan objects which we are unable to correctly track.
Additionally, this commit includes:
1. Properly implement safe cascade deletion of all participating
tables on soft deletion in the objects-gc task;
2. Make the file thumbnail related tables also participate in the
touch/refcount mechanism applyign to the same safety checks;
3. Add helper for db query lazy iteration using PostgreSQL support
for server side cursors;
4. Fix efficiency issues on gc related task using server side
cursors instead of custom chunked iteration for processing data.
The problem resided when a large chunk of rows that has identical
value on the deleted_at column and the chunk size is small (the
default); when the custom chunked iteration only reads a first N
items and skip the rest of the set to the next run.
This has caused many objects to remain pending to be eliminated,
taking up space for longer than expected. The server side cursor
based iteration does not has this problem and iterates correctly
over all objects.
5. Fix refcount issues on font variant deletion RPC methods
