feat(bus): the bus host runs an explicit Claude Code binary (#1561, row 68)

Browse Source 
MOSAIC_CLAUDE_BIN names the claude binary by absolute path instead of
finding it on PATH. scripts/bus-service.sh render|install --claude PATH
writes it into the unit (default: command -v claude in the installing
shell); the claude adapter, the launcher's version read and the seat
session environment all use it. Mos's Q18 ask: the unit's PATH found
/usr/bin/claude 2.1.259, which refuses claude-opus-5-5.

Candidate: round 2 manifest 21c1ab05, round 1 (a2008d8b) rebased onto
f2f2861b after row 55 changed docs/TOOLS.md and packages/cli/README.md;
the changed lines are byte-identical. Approved by Filbert (27349, 27374)
and Dewey (27350, 27375). Sage's gate on f2f2861b plus the patch: cli
112, seat 27, harness 57, nine scripts/test-*.sh 0 failed, Docker on.
