feat(agent-core): announce image compression and keep originals readable (#1304)
* feat(agent-core): announce image compression and keep originals readable

Every image ingestion point (ReadMediaFile, MCP tool results, clipboard
paste, REST upload/inline base64, ACP) now places a <system> caption next
to a compressed image stating the original vs. delivered dimensions, byte
size, and format, so downsampling is never silent to the model.

Originals stay readable: file uploads point at the stored blob, and
in-memory images are persisted into the session's media-originals dir
(content-addressed, size-capped, removed with the session; temp-dir
fallback when no session is known).

ReadMediaFile gains region (crop in original-image pixel coordinates,
delivered at full fidelity) and full_resolution (skip downscaling, with
an explicit error over the per-image byte limit), so the model can zoom
into fine detail instead of silently degrading on large images.

* fix(agent-core): exempt compression captions from the MCP text budget

The caption announcing an image's compression was inserted before the
shared 100K text budget was applied, so a chatty MCP result (page text +
screenshot) consumed the budget first and the caption was evicted — or
sliced mid-string into an unclosed <system> fragment — while the
downsampled image survived, silently reintroducing the exact degradation
the caption exists to report, and orphaning the persisted original.

Split the size-limit pass in two and reorder the pipeline: the text
budget now runs on the tool's own text BEFORE compression inserts
captions (exempt by construction), and the per-part binary cap still
runs after compression so compressible screenshots are kept.

* fix(agent-core): harden crop error reporting and document readback semantics

- cropImageForModel rejects non-finite region coordinates with a clean
  message instead of surfacing the codec's internal validation dump
- the full_resolution and cropped-region over-budget errors now include
  exact byte counts alongside the rounded sizes, so a file a hair over
  budget no longer reads "is 3.8 MB, over the 3.8 MB limit"
- read-media.md notes that re-reading a file without region or
  full_resolution reproduces the same downsampled image
