* Add prompt_id to progress_text binary WS messages
Add supports_progress_text_metadata feature flag and extend
send_progress_text() to accept optional prompt_id param. When
prompt_id is provided and the client supports the new format,
the binary wire format includes a length-prefixed prompt_id field:
[4B event_type][4B prompt_id_len][prompt_id][4B node_id_len][node_id][text]
Legacy format preserved for clients without the flag.
Both callers (nodes_images.py, client.py) updated to pass prompt_id
from get_executing_context().
Part of COM-12671: parallel workflow execution support.

* refactor: add prompt_id as hidden type, fix imports, add docstrings
- Add PROMPT_ID as a new hidden type in the Hidden enum, HiddenHolder,
HiddenInputTypeDict, and execution engine resolution (both V3 and legacy)
- Refactor GetImageSize to use cls.hidden.prompt_id instead of manually
calling get_executing_context() — addresses reviewer feedback
- Remove lazy import of get_executing_context from nodes_images.py
- Add docstrings to send_progress_text, _display_text, HiddenHolder,
and HiddenHolder.from_dict

* fix: send_progress_text unicasts to client_id instead of broadcasting
- Default sid to self.client_id when not explicitly provided, matching
every other WS message dispatch (executing, executed, progress_state, etc.)
- Previously sid=None caused broadcast to all connected clients
- Format signature per ruff, remove redundant comments
- Add unit tests for routing, legacy format, and new prompt_id format

* remove send_progress_text stub tests
Copy-paste stub tests don't verify the real implementation and add
maintenance burden without meaningful coverage.

* fix: always send new binary format when client supports feature flag
When prompt_id is None, encode as zero-length string instead of falling
back to old format. Prevents binary parse corruption on the frontend.
