docs(wiki): correct the install story now that all three packages are on PyPI Six pages still described the #66 breakage as current, three weeks after it was fixed. Verified against a clean virtualenv on 2026-08-10. - Installing: the PyPI path is recommended again; the git+https workaround is demoted to 'development tip' with an explicit warning that it pins a commit. Added the server install path. Corrected the Python 3.13 claim. - Troubleshooting: the unrecognized-arguments entry is now an upgrade instruction, not a workaround. The stale-MIT entry says it is fixed on PyPI and points at the two metadata defects that are still open (#56, #74). - Home: the warning banner inverted. - vs-Alternatives: 'installation is currently rough' replaced with the real remaining gap (fewer install channels), which is still honest but true. - Glossary + Your-First-Contribution: four gates -> nine required checks, six of which run locally; a green make setup no longer implies a green PR. - Your-First-Contribution: the walkthrough targeted #12, which is fixed and closed. Retargeted at #74. Removed the 'first human response within 3 working days' promise, which cited TRIAGE.md for a commitment TRIAGE.md has never made.
