* fix(#2645): emit [[agents]] array-of-tables in Codex config.toml
Codex ≥0.116 rejects `[agents.<name>]` map tables with `invalid type:
map, expected a sequence`. Switch generateCodexConfigBlock to emit
`[[agents]]` array-of-tables with an explicit `name` field per entry.
Strip + merge paths now self-heal on reinstall — both the legacy
`[agents.gsd-*]` map shape (pre-#2645 configs) and the new
`[[agents]]` with `name = "gsd-*"` shape are recognized and replaced,
while user-authored `[[agents]]` entries are preserved.
Fixes#2645
* fix(#2645): use TOML-aware parser to strip managed [[agents]] sections
CodeRabbit flagged that the prior regex-based stripper for [[agents]]
array-of-tables only matched headers at column 0 and stopped at any line
beginning with `[`. An indented [[agents]] header would not terminate the
preceding match, so a managed `gsd-*` block could absorb a following
user-authored agent and silently delete it.
Replace the ad-hoc regex with the existing TOML-aware section parser
(getTomlTableSections + removeContentRanges) so section boundaries are
authoritative regardless of indentation. Same logic applies to legacy
[agents.gsd-*] map sections.
Add a comprehensive mixed-shape test covering multiple GSD entries (both
legacy map and new array-of-tables, double- and single-quoted names)
interleaved with multiple user-authored agents in both shapes — verifies
all GSD entries are stripped and every user entry is preserved.
