feat: media:list command and skill guidance to reuse uploaded media

[giladresisi]

Adds CLI + skill support for the media listing from gitroomhq/postiz-app#1926:

• src/api.ts: listMedia(page, search) calling GET /public/v1/media
• postiz media:list [-s|--search] [-p|--page] (in src/commands/upload.ts, wired in src/index.ts)
• SKILL.md (Rule 2 note, examples, Media Upload section), QUICK_START.md, FEATURES.md, CHANGELOG.md: tell agents to look for an already-uploaded file with media:list and reuse its path instead of uploading again

Do not merge before gitroomhq/postiz-app#1926 is deployed, otherwise media:list hits a non-existent endpoint.

Companion: gitroomhq/postiz-docs#239.

Tested: npm run build passes; media:list, --search and --page 2 return the expected JSON against a backend with the new endpoint; a separate agent followed SKILL.md end to end (help text, listing, search, pagination) and created a draft post using a path returned by media:list, confirmed via posts:list.

📝 Walkthrough

Walkthrough

The CLI adds media:list to retrieve uploaded media with optional filename search and pagination. The implementation calls the media library API, prints JSON results, and documents reuse of returned media paths.

Changes

Media listing

Layer / File(s)	Summary
Media API and command execution src/api.ts, src/commands/upload.ts	PostizAPI.listMedia sends optional page and search parameters to /public/v1/media. The command prints and returns the JSON result and handles failures.
CLI command wiring src/index.ts	The CLI registers media:list with --search/-s and --page/-p options.
Media reuse documentation CHANGELOG.md, FEATURES.md, QUICK_START.md, SKILL.md	Documentation describes media listing, pagination, filename search, and reuse of returned .path values.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to dd3de

The new media listing command supports search and pagination, but invalid page inputs can be accepted and page 0 can silently fall back to an unpaginated request, creating a bounded CLI correctness risk. The PR is mergeable with explicit owner awareness or follow-up.

74-83: 🩺 Stability & Availability | 🔵 Trivial

Verify the backend prerequisite before merge.

This method calls the new /public/v1/media endpoint. Keep the merge gated on gitroomhq/postiz-app#1926 being deployed in every target environment. Without that deployment, media:list will fail with an API error.

In `@SKILL.md`:
- Line 174: After assigning EXISTING from media:list, validate that it is
neither null nor empty before invoking posts:create; print a clear error and
exit when no matching media is found, while preserving the existing posting flow
for valid paths.

In `@src/index.ts`:
- Around line 402-407: Update the page option configuration near the page option
definition to add validation requiring the supplied value to be an integer
greater than or equal to 1, while preserving its existing alias, type,
description, and default.

Apply the same fix in `@SKILL.md` at line 45.
