docs: fix AGENTS.md accuracy — add trigger-e2e to ado-script tree and export-fact-catalog to CLI index

## Agent Documentation Update

### Findings

| Area | Issue | File(s) |
|------|-------|---------|
| Architecture tree | `trigger-e2e/` directory missing from `scripts/ado-script/src/` listing | `AGENTS.md` |
| CLI documentation index | Only `export-gate-schema` listed as a hidden build-time tool; `export-fact-catalog` omitted | `AGENTS.md` |

### Applied Fixes

- [x] Added `trigger-e2e/` entry to the `scripts/ado-script/src/` architecture tree, with description matching `docs/ado-script.md`
- [x] Updated the `docs/cli.md` index entry to list both `export-gate-schema` and `export-fact-catalog` as hidden build-time tools

### Notes

Verified against:
- `scripts/ado-script/src/` directory listing confirms `trigger-e2e/` exists alongside `executor-e2e/`, `prepare-pr-base/`, `shared/`, etc.
- `src/main.rs` `Commands` enum confirms both `ExportGateSchema` and `ExportFactCatalog` are `#[command(hide = true)]` variants
- `docs/ado-script.md` lines 109 and 568 already document `trigger-e2e/` correctly — this brings `AGENTS.md` into sync
- `docs/cli.md` lines 186–192 already documents both hidden tools correctly — this brings `AGENTS.md` into sync

Review AGENTS.md, then compare its scripts/ado-script/src/ tree with the directory listing and check src/main.rs for the hidden Commands variants. Use docs/ado-script.md and docs/cli.md as the existing references; done means AGENTS.md accurately lists trigger-e2e and both hidden build-time CLI tools, with the documentation changes verified.
