v0.5.0

9154c1b: Rename intent handle methods to a clearer claim vocabulary; add AbloProvider bootstrapMode.

BREAKING — on the model intent handle (ablo.<model>.intent(id)): acquire→claim, acquireOrAwait→claimOrWait, settled→whenFree, release→finish, revoke→cancel. The lower-level IntentHandle / IntentLeaseHandle (ablo.intents.*) are unchanged.

Also: AbloProvider gains a bootstrapMode prop ('full' | 'none') to skip the baseline pull on read-light pages; StaleContextConflict gains an optional conflictingFields; README + JSDoc clarity pass and a new HTTP API section.
