Jakub Piasecki d4a712c401 refactor(gesture): rename the momentum-free flag to momentum (#732)
`settle: true` collided with the runner's other `settle` — waiting for
the tree to quiesce — which is the very thing a swipe step does after
every dispatch, whichever way the flag is set. One sentence of the flow
skill used both senses at once.

This names the physics instead: `momentum: false` is the momentum-free
gesture, and the natural fling is the default the prose already
described.

### Renamed

| surface | before | after |
| --- | --- | --- |
| `swipe` flow directive | `settle: true` | `momentum: false` |
| `gesture-swipe` param | `settle` | `momentum` |
| `gesture-drag` param | `settle` | `momentum` |

The directive passes the flag straight through to the tools, so all
three move together. `momentum: true` is the default and normalizes to
absent, mirroring what `settle: false` did — parse/serialize stay exact
inverses.

### Also

- Recording summary label `(settle)` → `(momentum-free)`
- Internal constants → `MOMENTUM_FREE_EASE_EXPONENT`,
`MOMENTUM_FREE_MIN_STEPS`
- `flow-run` tool description and `argent-create-flow` skill updated

### Testing

`tsc -b`, eslint (`--max-warnings 0`) and prettier clean; `test/flows` +
`test/tools` pass 671/671, including a new case covering the
legacy-spelling rejection.
