lua/td.lua wraps the `td` CLI (from setup_env dotfiles/bin/td) and
adds auto-tid generation: <leader>ts on a todo line appends
^tid-YYYYMMDD-HHMMSS, writes the buffer, then starts the timer.
<leader>tp stops, <leader>tr shows a floating-window report.
Also exposes :TdStart/:TdStop/:TdReport user commands.
Vault root is detected by walking up from the buffer file looking
for time.csv or .obsidian/, so the CSV is written at the vault
root regardless of the buffer's depth.
