VALIDATION_REJECT_CODES and PARSE_REJECTED to distinguish accepted-code sets
from wording contracts: describe VALIDATION_REJECT_CODES as an accepted set, and
list PARSE_REJECTED separately as a regular-expression/device-wording contract.
Avoid implying both symbols are interchangeable contract shapes.

Learning: For the `explain` command documentation, `commands/explain/examples.md` specifies the finished target contract, not the current implementation phase. `commands/explain/README.md` contains the phase inventory and must map omitted phase fields to the issues and examples that will make them green. Future phase gaps must add fields without changing the finished example contract.

Pull request overview
Adds the B2 “value” token fill for explain --tokens, claiming leaf value-byte spans (including array-literal member leaves) from data.values.occurrences on the residual partition before operator scanning, and updates the token census/docs accordingly.
Changes:
- Introduces
src/explain/value-tokens.tswithvalueSpans()to claim leaf value spans (quotes-included) on residual ranges and integrates it intoexplainCommand()fill order (spans → arg → value → operator). - Adds unit coverage for the new value fill and updates the token census fixture +
commands/explain/README.mdto reflect new classified bytes/tokens. - Expands test/integration guidance docs around device-dependent expectation contracts and long-term verification.

Third B2 fill after spans + arg. Claims argument value bytes and
leaf array-literal members on the residual left by those fills,
before the operator scanner sees it. Source is
data.values.occurrences (prefix-safe, carries array interiors via
parent references), not Argument.valueSpan — which is why
:local a {1;2;3} yields three leaves even though lexArguments
refuses the statement wholesale (a variable value).
Leaves only via Set<parent> so a container containing its members
is not a self-overlap throw in buildTokens. Span is
quotes-INCLUDED by contract; the quotes/escapes fill is a separate
staging row and must not double-claim. ~1,720 bytes already held
by variable-* spans are clipped to residual — same shape as
arg-tokens.ts — with the overlap throw as the safety net.
Vocabulary is provisional until #264 B5: one value class
(class value, ev e9) regardless of shape/observed/schema type.
The three #225 facts stay in data.values[], joined by offset.
Fill order is now spans -> arg -> value -> operator, whose
ordering retires the glued-dot operator residue noted in
operator-tokens.ts.
Census ritual: 34.89% -> 47.55% (180,826 value bytes net,
19,128 value tokens) over the 948-script pinned corpus.
Operator shrinks by 176 bytes — the glued-dot paths the operator
fill read as concatenation because no fill owned value bytes yet
(name=router.lan, www.mikrotik.com, options=dsv.remap).
Update the fixtures/README via explain:token-census ritual.
Evidence: operator shrink measured on corpus; partition invariant
holds on fixtures and corpus; overlap/clipping verified via
direct buildTokens + residual tests.
Fixes #295
