Subject: [PATCH] Cut RS-L: the leaf gains Title, moves to epoch v2, and two
 grammar doors

Q-RS1 ruled B: a new bounded text type, Title (1-200 bytes, never empty),
replaces Short on all four leaf titles -- campaign, cut spec, and the two
new fields on question and ruling. The epoch moves anyway in this cut, so
tightening the two existing titles now avoids a second epoch bump later
just to make a title required.

PIPELINE_SCHEMA_EPOCH and all thirteen type ids move to .v2. The thirteen
schema files are renamed and regenerated, and index.json/README.md follow.

Two public doors join Slug::validate_slug on the same pattern:
OrgRepo::validate_org_repo and Label::validate_label, each delegating to
the grammar its own document field is already held to. RS-3 will read the
organ's repo and cut aliases through these.

Tests: the_org_repo_and_label_doors_are_the_grammar and
question_and_ruling_carry_a_title (37 total, up from 35). Mutation suite
tools/eureka-readside-leaf-mutations.psd1 (L1/L1L, L2/L2L, L3/L3L) verified
killed against M0.

No other consumer in this workspace depends on epiphany-pipeline as a
Cargo dependency; epiphany-core's runtime_spine stand-in hardcodes a
pipeline-shaped type id deliberately (RS-L's negative grep excludes it) and
is unaffected since its test only checks the "epiphany.pipeline." prefix.
