v0.1.0

Added

• stm: find the app on localhost, discover pages (sitemap, then links), full-page screenshots into screenshots/<app>_<timestamp>/, every file named <page>_<timestamp>.png, plus a fold/ viewport image per page.
• Change detection against the previous snapshot (sha256), with changed, new and removed lists.
• --json for agents: absolute paths, one line on stdout, printed even when pages failed.
• stm list, stm open, stm skill, --mobile, --max, --out, --url.
• Agent skill (skills/stm/SKILL.md) installable with npx skills add mdsohaib/screenshot-time-machine, and a Claude Code plugin marketplace file.
• Browser bootstrap: cached Playwright build, then Chrome, then Edge, then a one-time headless-shell download.
• Dev toolbars hidden, dev error overlays flagged; animations frozen; lazy images loaded; incremental manifest; graceful SIGINT/SIGTERM.
• Paths in the summary and in --json always use forward slashes, on every platform.
