htmxr 0.2.0

Breaking changes

htmxr_is_htmx() renamed to hx_is_htmx() to follow the hx_ prefix convention applied to all exported functions.
hx_button() parameter order changed: id is now first and required (was label). Update calls like hx_button("Click me") to hx_button("my-btn", label = "Click me").
hx_table() parameter id renamed to tbody_id to clarify that the id is applied to the <tbody>, not the <table>.

hx_trigger() — adds an HX-Trigger response header to a plumber2 response, causing htmx to fire a client-side event immediately after the response.
hx_trigger_after_swap() — same, but fires after htmx swaps the new content into the DOM (HX-Trigger-After-Swap).
hx_trigger_after_settle() — same, but fires after htmx settles (HX-Trigger-After-Settle).
The event argument accepts a character vector (multiple events) or a named list (events with JSON detail payloads), serialised without external dependencies.

Fix invalid 'plumber2' URL in vignette (was pointing to a non-existent GitHub repository, now points to https://plumber2.posit.co/).
Quote technical terms in DESCRIPTION to comply with CRAN spell check conventions.
Add Depends: R (>= 4.1.0) for native pipe |> compatibility.
