fix: get_thumbnail size limits, default=small, quality quirk docs (v0.3.5)
- Default size changed large → small (avoids MCP buffer overflows)
- Hard limit: return Error: when thumbnail exceeds ~2 MB base64 (1.5 MB raw)
- Soft limit: add "warning" field to JSON when thumbnail exceeds ~500 KB base64
(375 KB raw), advising to use size='small'
- Constants _THUMB_ABORT_BYTES / _THUMB_WARN_BYTES moved to module level
- 6 new tests for size cap/warning/default/DSM-error paths (113 total)
- SPEC.md: document quality-ignored quirk, size ranges, soft+hard limits
- CLAUDE.md: DSM Quirks entry for Thumb quality/size behaviour
