fix: pass actual file creation date to frontmatter generation

Previously used current date instead of file.stat.ctime for the created
field, causing incorrect timestamps in generated frontmatter. Also add
file metadata (created, modified, size) to template application context.

 - tags: a small set of specific, reusable tags. Use lowercase with no spaces and no # prefix. Prefer hierarchical tags using forward-slash notation (e.g. "type/person", "projects/active") over flat generic tags. Reuse the vault's existing tags (listed below) whenever one genuinely fits the note — this keeps the vault's tagging consistent. Only coin a new tag when none of the existing tags describes an important topic of the note.
