docs(planning): drop GitHub repo rename from v0.1.5 scope

The CR §9.2 decision to rename ayhammouda/python-docs-mcp-server to
python-stdlib-mcp was reversed on 2026-05-14. The repo and the PyPI
package both keep their existing name.

This commit goes with the previous one (revert of PR #26) — together
they undo every in-repo URL rename and restore the v0.1.5 scope to
the four remaining workstreams (positioning, PyPI publish, benchmark
harness, launch post).

The positioning anchor ("canonical Python stdlib oracle / always free,
always MIT / token-frugal") and the phase 9/10/11 backlog are kept
unchanged — neither depends on the rename.

 ## Current
 
 - **v0.1.4** — shipped (pre-PyPI; installed via `uvx --from git+…`)
-- **v0.1.5** — in progress. Five coordinated workstreams: positioning lockdown ("canonical Python stdlib oracle for AI coding agents — always free, always MIT, token-frugal"); first PyPI publish via Trusted Publishing; GitHub repo rename to `python-stdlib-mcp` (PyPI package name stays `python-docs-mcp-server`); benchmark harness against competing docs MCPs; coordinated launch post on a personal blog, dev.to, and Show HN.
