Vendor the ASN.1 modules the codecs are verified against; untrack IDE churn

asn1/
Three tests assert exact bytes - CamEncodeGoldenTest, DenmAirReceiveTest and
SpatemUperCodecTest - and their expected values came from asn1tools compiled
against ETSI modules that existed only as an untracked working copy on one
machine. A golden-byte fixture nobody else can regenerate is a fixture nobody
can safely touch, so the modules are now in the repo.

Only the seven .asn files those tests need are copied, 576 KB of a 4.2 MB
checkout; the upstream Rust parser is not used by this project at all. Verified
sufficient in isolation: copied into an empty directory, all three specs compile
and reproduce the committed golden CAM bytes byte-identically.

Source is consider it GmbH's C-ITS-Parser (github.com/consider-it/C-ITS-Parser)
at f457426, MIT licensed - LICENSE is retained alongside as that requires. The
schemas themselves are ETSI's standard definitions; upstream's contribution is
assembling them into a compilable set. asn1/README.md records the provenance,
which module pairs with which message, and the rule that matters: never
regenerate a golden fixture from this project's own encoder, because sharing a
mistake between encoder and decoder is exactly the failure these files exist to
catch.

Doc references in the codecs and tests now point at asn1/ instead of the
untracked checkout, and C-ITS-Parser/ is gitignored so the working copy beside
the project is never picked up.

Untracked local state
- .idea/deploymentTargetSelector.xml rewrites itself on every deploy, so it has
  been showing as modified in essentially every commit. Along with
  deviceManager.xml, appInsightsSettings.xml and studiobot.xml it is per-machine
  state, not project configuration.
- obu-firmware/sdkconfig.old is ESP-IDF build output - it is the previous
  sdkconfig, rewritten on every build. sdkconfig.defaults remains tracked, since
  that is the configuration actually chosen.

All five stay on disk; only the tracking is removed. Also ignores
.claude/settings.local.json, which is per-machine, while leaving the skills
beside it committable as project knowledge.

# ETSI ASN.1 modules
The ASN.1 schemas this project's UPER codecs are validated against. **Schemas only** — no parser
code. Nothing in the app or the firmware reads these files at build or run time; they exist so the
hand-written codecs in `app/src/main/java/.../domain/asn1/` can be checked against an independent
implementation.
## Why this is here rather than just documented
Three of this project's tests assert exact bytes:
- `CamEncodeGoldenTest` — the CAM this app transmits, byte for byte
- `DenmAirReceiveTest`, `SpatemUperCodecTest` — real captured frames with field values
Those expected values were produced by decoding with `asn1tools` compiled from these modules. Without
them the fixtures cannot be regenerated or re-verified, and a golden-byte test you cannot regenerate
is a test nobody can safely touch.
This matters because the project has shipped the same class of bug three times: a field encoded with
the wrong number of bits, which this codebase then read back with the *same* wrong number. Phone and
ESP32 agree perfectly with each other and with nothing else, so every internal round-trip test passes
while the frames on air are malformed (`CurvatureCalculationMode`, the GeoNetworking reserved bytes,
`yawRateConfidence`). Only a second, independent implementation catches that — which is what these
modules provide.
## Provenance
Taken from consider it GmbH's C-ITS-Parser:
- <https://github.com/consider-it/C-ITS-Parser>
- commit `f457426efc2486fac49a02fc9a1c8c7762d160e9`
- MIT licensed — see `LICENSE`, retained here as the licence requires
Only the seven `.asn` files below are copied, out of a 4.2 MB checkout. The upstream Rust parser is
not used by this project in any way. The schemas themselves are ETSI's standard definitions; the
upstream repo's contribution is assembling them into a compilable set.
| file | used for |
|---|---|
| `cam_1_4_1.asn` + `cdd_1_3_1_1.asn` | CAM encode/decode |
| `denm_1_3_1.asn` + `cdd_1_3_1_1.asn` | DENM decode |
| `spatem_2_2_1.asn`, `mapem_2_2_1.asn`, `dsrc_2_2_1.asn`, `cdd_2_2_1.asn` | SPATEM/MAPEM decode |
Note CAM/DENM use the release-1 common dictionary (`cdd_1_3_1_1`) while SPATEM/MAPEM use release 2
(`cdd_2_2_1`). Both are needed; they are not interchangeable.
These seven were verified sufficient on their own: copied into an empty directory, all three specs
compile and reproduce the committed golden bytes.
## Regenerating a fixture
Requires Python with `asn1tools` (verified with 0.167.0):
```python
import asn1tools
spec = asn1tools.compile_files(["asn1/cam_1_4_1.asn", "asn1/cdd_1_3_1_1.asn"], "uper")
spec.decode("CAM", raw_uper_bytes)
```
For SPATEM, compile `spatem_2_2_1.asn`, `mapem_2_2_1.asn`, `dsrc_2_2_1.asn`, `cdd_2_2_1.asn`
together and decode `"SPATEM"`.
**Never regenerate a golden fixture from this project's own encoder output** — that is precisely the
mistake these files exist to catch. Regenerate through `asn1tools`, or the test is worthless.
## Updating
Re-pin deliberately, not casually. If a newer ETSI release is adopted, copy the new modules, then
re-run the golden-byte tests and confirm any change in expected bytes is explained by the spec
change rather than by a decoder regression.
