Teknium 4920c5940f feat: auto-detect local file paths in gateway responses for native media delivery (#1640) ...

Small models (7B-14B) can't reliably use MEDIA: or IMAGE: syntax. This
adds extract_local_files() to BasePlatformAdapter that regex-detects
bare local file paths ending in image/video extensions, validates them
with os.path.isfile(), and delivers them as native platform attachments.

Hardened over the original PR:
- Code-block exclusion: paths inside fenced blocks and inline code are
  skipped so code samples are never mutilated
- URL rejection: negative lookbehind prevents matching path segments
  inside HTTP URLs
- Relative path rejection: ./foo.png no longer matches
- Tilde path cleanup: raw ~/... form is removed from response text
- Deduplication by expanded path
- Added .webm to _VIDEO_EXTS
- Fallback to send_document for unrecognized media extensions
