* feat(ps): add craft-ps with an EPS reader (read feature)
The reading half of craft-ps (#115): a clean-room PostScript interpreter
that runs an EPS and returns what it paints as a one-page vector PDF of
its bounding box, colours kept, so apps can draw and export EPS as a
placed PDF. Moved from DesignCraft (storytold/designcraft, where it was
written for placed EPS), with its app-specific names made neutral.
Written from the PostScript Language Reference (3rd ed.), the EPS
specification, the Type 1 Font Format and Adobe TN 5012/5176/5177.
Covers the language, paths, clipping, strokepath, device/Separation/
DeviceN/Indexed/ICCBased/Lab colour, images with lazily decoded filters,
shadings 1-7 and patterns, and Type 1/3/42/CFF/CID text through CMaps,
horizontal and vertical.
Bounded: each operator charges work proportional to its operands
against the step limit as it goes, every byte read or decoded counts,
copies count against the memory cap; defaults 50 M steps / 1 GiB, and
20 M / 256 MiB on wasm32. No panics (deny lints, fuzzed in debug
builds). 34 tests, the Type 42 one on a TrueType font built in the
test. No new external crates: pdf-writer, miniz_oxide, weezl, skrifa
and kurbo are already locked at these versions.

- `Encoder::with_application` checks the channel count before clamping
the bitrate, so 86 channels or more return `Error::Channels` instead
of panicking in `clamp`. Tested with 86 and 255.
- The ffmpeg oracle test skips a missing `opus`/`libopus` decoder
through the testkit's `skip`, so `CRAFT_MEDIA_REQUIRE_ORACLES=1` fails
it.
- README: the encode example pads at least the pre-skip after the audio
before rounding up to a frame, so the encoder delay is flushed; the
MP4 note says an explicit edit replaces the `media_start` edit and
gives its fields.

EffectCraft's `effectcraft-opusenc` as `opus::encoder` (and
`opus::Encoder`) behind `opus-encode`: SILK, hybrid and CELT, 48 kHz,
20 ms frames, mono or stereo. The constructors and `encode_float`
return `Result` instead of panicking. `Bandwidth` is one type for the
decoder and the encoder, and the two `Mode` enums convert into each
other. `encode` now turns on `opus-encode`.
The encoder tests (modes, ffmpeg's two Opus decoders as oracles) and
`TrackDecoder` on Opus without an `OpusHead` come with it.
