Jakub Zych 6cfa0c55d2 refactor: drop 12 runtimes, keep Claude, Codex, OpenCode, Cursor, ZCode, Antigravity
Removes kilo, kimi, kimi-code, copilot, windsurf, augment, trae, qwen, hermes,
cline, codebuddy and pi end to end: capability descriptors, installer branches
and converters (bin/install.js 14.9k -> 11.2k lines), TypeScript converters,
hook surfaces and runtime homes, review lanes qwen/kimi-code, the two pi
migrations, Kimi payload normalization in the hook guards, dead hostBehaviors
vocabulary, launcher home probes, fixtures, runtime-specific tests and the
prose that presented them as supported.

Installer output for the six kept runtimes is byte-identical to before the
prune. The Kimi tool-vocabulary tests in workflow-guard, read-guard and
read-injection-scanner are left in place pending a decision.

/**
* Drift-guard + collapse: getGlobalConfigHomeFragment must be the SINGLE source
* of truth for the runtime → global config-home path-fragment mapping used by
* `getConfigDirFromHome` in bin/install.js for hook path.join() codegen.
*
* Collapses the prior branch `if (runtime === 'x') return "'...'"` chain
* (install.js ~514-543) into one table — ADR-1239 Phase B / #1679, AC2 slice 2.
*
* Invariants pinned here:
* 1. Each table runtime returns its exact verbatim source fragment
* (byte-identical to the prior chain — golden install parity asserts the
* generated hook output is unchanged).
* 2. claude + unknown + empty fall back to the default "'.claude'" fragment.
* 3. antigravity is intentionally NOT in the table (handled dynamically by the
* caller via resolveAntigravityGlobalDir).
* 4. Drift guard: every registry runtime EXCEPT {claude, antigravity} has a
* table entry — so adding a runtime forces a deliberate fragment decision
* here (the add-a-host tax this collapse removes).
*
* ADR-1239 Phase B (#1679). Behavioral tests only.
