What

Adds media/file/image downloads to the CLI, and stops messages from silently dropping media-only messages.

• teams media <chat> [id] — downloads the newest (or a given) voice note / media / image message. The playable/viewable object URL is fetched with the ic3 token; the output extension is derived from the response content type (webm/mp4/jpg/png).
• teams file <chat> [match] — downloads file attachments by file-name substring or message id, riding the pre-authed tempauth link (botFileProperties.url, SharePoint objectUrl fallback). A 403 gets an explicit hint that tempauth links expire shortly after sending and the file needs re-sharing.
• messages marker rows — media/file/image-only messages previously produced empty stripHtml content and were dropped from the output entirely (an image-only message was invisible in the conversation read). They now render [voice note 28s — media id …], [file: report.pdf — file id …], [image 800w — img id …], and captioned images get an inline [image …] marker appended to the text.
• The extractors (extractMedia / extractImage / extractFile) are exported from formatting.ts and unit-tested against real message payloads.

Where the URLs come from

• Voice notes/media: properties.cards JSON → content.media[0].url (…/v1/objects/<ref>/views/audio), duration parsed from the PT..S string.
• Images: the raw HTML <img src="…/v1/objects/<ref>/views/imgo"> inside the message content (with & unescaped, width captured when present).
• Files: properties.files JSON.

Validation

Tested against live Teams traffic: voice-note downloads come back byte-identical to the browser blob, and image downloads come back byte-identical to a manual object-URL fetch with the same bearer token. 14 new unit tests (106 total, all green); biome check clean; tsup build clean.

Notes

• Media downloads hit the object host directly (not the chatsvc base URL) and therefore need the raw ic3 token — the PR uses the existing getToken("ic3") accessor.
• Image marker rows include the width when the <img> tag carries one ([image 800w …], else ?).

Friendly ping — happy to rebase this onto current main if anything has drifted. I'm also sending a few follow-up PRs (#30–#32: --json output, HTML send, file attachments) built on this line of work; no rush, just letting you know they're coming.
