Tab completion used a generated table (pm3line_vocabulary.h, refreshed by
hand via `make commands`) that drifted from the real command tables: new
commands were missing (e.g. `hw bwm*`), removed ones lingered, and the
"offline" flag depended on the platform of whoever regenerated it
(IfPm5() returns true offline on PM5 builds).
Build the vocabulary at startup instead:
- cmdparser: add walkCommandsRecursive(), a tree walk using a fourth
internal sentinel (XX_internal_command_walk_XX) next to the dump ones.
It hands each leaf to a visitor as its command_t chain (ancestors +
leaf). A dispatch counter detects entries shown like a category but
with their own parser (reveng) and reports them as leaves.
- pm3line_vocabulary: dynamic vocabulary holding the IsAvailable()
predicates of every command and its ancestor categories, so completion
applies exactly the rule CmdsHelp() uses, live, for both offline and
connected devices. Script entries ("script run <relpath>") come from
the same directories `script list` scans, sorted, including
subdirectories with the path `script run` needs.
- pm3line: readline and linenoise completers consume the live vocabulary.
The walk runs with output disabled so category handlers stay silent.
- Drop pm3_help2list.py and the header regeneration from `make commands`.
Behaviour change: entries whose category is hidden by `help` (e.g. `mem`,
`usart` offline) are no longer offered, matching `help`; when connected,
commands the device does not support are no longer offered either.
