Aligns with the two-argument calling convention used elsewhere in the
script, where the bold label and the highlighted value are passed as
separate arguments. Also moves the preset name out of the error string
in load_preset for the same reason.

Previously only output_pixel_format was mentioned. All three variables
(input_codec, input_pixel_format, output_pixel_format) are now listed
with descriptions in the script header comment, the README, and the
man page.

Both the README and the man page now explain that the script always
passes -map 0, -map_metadata 0, -map_chapters 0, and -c copy to
ffmpeg before appending the preset's ffargs array. This context is
important for preset authors, who only need to override the streams
they intend to re-encode.
Also fix a minor blockquote rendering issue in the README (missing
blank line before the fenced code block in the PATH note).

Batch transcode helper for media files using ffmpeg. Encoding parameters
are supplied by user-defined preset files (shell snippets that set an
`ffargs` array) stored under
${XDG_CONFIG_HOME:-$HOME/.config}/transcode.sh/presets/.
Key capabilities:
- Probes input codec and pixel format via ffprobe; derives an output
pixel format that preserves chroma subsampling and bit depth.
- Per-user and per-invocation codec skip lists to leave already-encoded
files untouched.
- Atomic in-place replacement: encodes to a temp file in the same
directory, then renames on success.
- --only-if-smaller: discard the result if it is larger than the
original.
- --saving: append filename, original/new sizes and percentage saved to
a log file after each successful encode.
- --dry-run, --verbose, --quiet, --nice and --continue flags.
- Respects the NO_COLOR standard.
- Script hardening: strict PATH, safe IFS, errtrace, nounset, pipefail.
Also included:
- Man page (transcode.sh.1)
- Bash completion script (transcode.sh.bash-completion)
- README.md
- .gitmessage commit message template
