chore/Bump-mthds-0.15.0 · L-260922-5f7eeb — the exact mthds pin outlived its reason

[lchoquel]

Moves the exact mthds pin from 0.14.0 to 0.15.0. pipelex has pinned mthds==0.15.0 exactly since 0.60.0, so the two packages could not be installed together; this restores that. Nothing in the client changed with the move, and the local method-files codec stays beside mthds.protocol.method_files until PipelineRequestError's base class is settled upstream, which docs/architecture.md now records.

Closes L-260922-5f7eeb

Summary by cubic

Moves the exact mthds pin from 0.14.0 to 0.15.0 so pipelex and pipelex-sdk can be installed together again: pipelex has pinned mthds==0.15.0 exactly since 0.60.0, and two exact pins on different versions left the pair unresolvable. Nothing in the client changed with the move.

Breaking changes in 0.15.0 — none of them affect this SDK:

• The one breaking cut (ConceptAbstract reduced to a name, StuffAbstract dumping its concept as the ref string) sits in protocol models this SDK does not build on.
• The base client's run-source guard now rejects a protocol arg smuggled through extra before building the body, which this client's own guard already did.
• The canonical method-files pair ships as mthds.protocol.method_files; this package keeps its own parse_method_files / serialize_method_files until PipelineRequestError's base class is settled upstream, and docs/architecture.md now records the reason.

Closes L-260922-5f7eeb.
