fix(workplans): adopt ADR-007 derived identifiers for unregistered records
These workplans exist only in the retired local hub. Their random pre-ADR-007
identifiers are refused by C-06 as stale references, so they cannot be
registered. Deriving from the canonical record id takes no identity from
anything: central does not hold them and the old ids die with the cache.

Records central already holds were deliberately left untouched.

# ESRC-WP-0002 — HTML and Markdown source representations
The PDF slice (ESRC-WP-0001) established the ingest boundary and contract shape.
This workplan extends ingest to HTML and Markdown sources, producing the same
`{ document, representation }` pair over engine-owned contracts.
## Decisions (ADR-0003)
- HTML maps to `representationType: "html-dom"`; Markdown to
`"markdown-rendered"`.
- Pageless formats omit `pageMap`; `offsetMap` is a single synthetic page-1
range covering `[0, canonicalText.length)`.
- Inline fixtures owned by this repo (no PII); PDF corpus rules unchanged.
## Sketch
```task
id: ESRC-WP-0002-T01
status: done
priority: medium
state_hub_task_id: "f875c025-2c08-56d7-bbde-60e0643a7b9c"
```
Define the HTML/MD representation contract with `citation-engine`; agree
`representationType` and any offset/page semantics for pageless formats.
```task

state_hub_task_id: "e7936d67-188d-50f3-8dc8-684c9f03fb4a"
```
Implement `ingestHtml` / `ingestMarkdown` in `src/html/` and `src/markdown/`,
reusing `fingerprintBytes` and the canonical-text normalizer.
```task

```
Add fixture-driven contract tests mirroring the PDF suite; decide fixture
ownership per ADR-0002.
