## Summary
`Pipeline.Run` already accepts an `override_params` map (keyed by
`cpnID`, override-wins) that is merged into each component's params at
compile time via `canvas.WithOverrideParams`. `PatchDSL` performed a
byte-for-byte equivalent merge by baking `ParserConfig` into the DSL
text before compilation, so `runPipelineWithDSL` applied the same
`Doc.ParserConfig` twice with no effect.
## Change
- Delete the now-dead `PatchDSL` function
(`internal/ingestion/pipeline/pipeline.go`); it had a single call site.
- In `runPipelineWithDSL`, compile the DSL unchanged and pass the
extracted component params to `Run` as `override_params`.
## Behavioral note (important)
Previously `PatchDSL` was also the channel that delivered the tenant LLM
id into Extractor components: it baked `parserConfig` — after
`common.InjectExtractorLLMID(parserConfig, Tenant.LLMID)` had injected
`llm_id` — into the DSL. The old `Run` override_params re-cast
`Doc.ParserConfig` (which intentionally omits `llm_id`). So removing
`PatchDSL` while keeping that re-cast would have silently dropped LLM id
injection. This change passes the local `parserConfig` (the
LLMID-injected copy) to `Run`, preserving the prior behavior.
The DSL string returned by `runPipelineWithDSL` is only consumed by
`recordPipelineLog` (structure storage) and `ExtractPayload` (which
reads the terminal structure, not params), so returning the original DSL
is equivalent.
## Test plan
- `bash build.sh --test ./internal/ingestion/task/...
./internal/ingestion/pipeline/...` — both packages pass.
- `gofmt` clean; pre-commit hooks pass.

### Summary
1. list and get by id API for builtin DSL
2. add DSL default component param values validation
3. remove all hard code keys for parser config
