v0.5.4 — seven MCP/ADT seam bug fixes

Seven bugs surfaced in one real-world ABAP refactor session against a ~147 KB class (/FGLR/CL_FLEET_TRANSFER) on on-prem E4D. All sat at the MCP↔ADT seam and were invisible to the pure-unit-test suite.

Full write-up: docs/bugfix-2026-05-15.md

Added

• adt_set_source_chunked — multi-call write protocol for class bodies that don't fit in one MCP call (10-min TTL buffer, 4 MB cap, strict ordering, partial-source guard at commit).
• adt_get_source.firstLine / lastLine / onlyMethod — pagination + method-scope slicing with totalLines / totalBytes / scope / truncated metadata.
• adt_set_source.acknowledgePartial — explicit bypass for the new partial-write guard.
• adt_activate.processRedoneOOSourceVersionOnly / preauditRequested — recover from "Object components locked in request and separate task" 403s.
• adt_lock.transport — forwarded as corrNr=<TR>. adt_set_source and adt_delete_object now forward transport to the LOCK call as well.

Fixed

• adt_set_source partial-write guard — detectPartialSource() rejects input whose first non-comment line is not a recognised top-level ABAP keyword. PUT on ADT is atomic; previously a chunk sent as a "diff" silently deleted the rest of the include.
• parseAdtError no longer drops CTS diagnostics — LONGTEXT and T100KEY-V1..V4 are extracted from both <entry key="…"> and <property name="…"> shapes, surfaced as error.properties.longText and error.properties.t100.

Investigated

• Method-scope class URI does not exist server-side — ADT Eclipse fetches the full implementations include and slices client-side. adt_get_source.onlyMethod is the practical equivalent.
