fix(copilot): mirror transactional Node hooks

 Cline CLI 3 and Cline IDE use separate file-hook loaders. SDK adapters target CLI 3, write only `$CLINE_DIR/hooks`, preserve its hybrid `tool_call`/`preToolUse` and `tool_result`/`postToolUse` payload, and emit pure JSON cancellation controls. The IDE variant discovers runtime `--hooks-dir`, Documents, and `.clinerules/hooks` roots; Windows selects exact `.ps1` files and macOS/Linux select executable extensionless files. Both runtimes continue after hook crashes, timeouts, and invalid controls while recording the failure.
 
-GitHub Copilot command `preToolUse` hooks deny on crashes and every non-zero exit. Command timeouts continue through the normal permission flow, so `timeout_failure_mode` records that explicit exception when it differs from `failure_mode`.
+GitHub Copilot CLI loads user hook files from `$COPILOT_HOME/hooks` or `~/.copilot/hooks` and combines them with policy, repository, inline settings, cross-tool Claude, and plugin sources. Elydora owns one user file with exact `preToolUse`, `postToolUse`, and `postToolUseFailure` handlers and preserves native camelCase fields, including `toolResult` and `error`. Effective settings precedence controls `disableAllHooks`; each managed file also retains its independent disable flag. Command crashes and non-zero exits deny pre-tool execution, while command timeouts continue through the normal permission flow.
 
 Cursor uses the same `preToolUse` and `postToolUse` contract across its CLI and IDE. User, project, and enterprise hook sources merge by documented priority; command exit code `2` denies an action, while per-script `failClosed` controls crash, timeout, and invalid-output behavior.
