jot v1.6.0

This release makes the document viewer substantially more useful for real developer files instead of idealized demos.

What's new

Markdown preview now handles tables, nested lists, task checkboxes, strikethrough, nested blockquotes, preserved line breaks, continuation paragraphs, fenced code blocks inside list items, pipe-heavy tables, and internal section links.
The local viewer now supports YAML, YML, TOML, CSV, .env and .env.*, TXT, LOG, and JSONL files in addition to the existing PDF, Markdown, JSON, and XML support.
YAML and TOML render through the same structured tree viewer as JSON, so nested config files can be explored instead of dumped as raw text.
CSV files now open in a themed table view, and env files render as key/value rows with values masked before they ever reach the page.
Added root-level sample fixtures for every supported viewer format to make smoke testing and manual QA faster.

The markdown renderer no longer breaks common README and GitHub-export formatting patterns that used to fall back to raw text or malformed structure.
Plain-text style files now preserve exact line structure in the viewer instead of flattening formatting.

GitHub Actions release jobs are currently disabled, so the v1.6.0 binaries and checksums were built locally and uploaded manually.
